I have found the best way to increase your mpg is to not go up hill. LoL
I hate it when your rolling along coming to a hill and some jerk in front of you slows you down becouse they want to keep to 10 mph below the speed limit 😡
@@markdunbar8219 Some trucks can't go faster... like mega carrier trucks. They are governed and have reduced torque. My company turns our trucks down considerably and it sucks!
Mark Dunbar that’s me lol. I’m ungoverned but the sweet spot for my rig is 65mph.
thats funny.. i found the best way to get better mileage is to drive down hill!
@@dmbworks8094 And get pulled/pushed by the air ;)
The most important thing for fuel economy is the weight ofthe drivers right foot. If to heavy it causes excessive fuel consumption and increases general wear and tear on the vehicle.
I just bought a Toyota Hilux 1996 and these are things I am thinking, as well as to preserve the turbo where possible..
BINGO!!!!
I use cruise control on the highway. My right foot means nothing . Fuel quality and aerodynamics are the most important.
Just be safe and speed up in a timely fashion on an on ramp
Highway speeds make the biggest difference in my fuel economy. Driving 55 vs 65 changes MPG for big 7.3 IDI engine from 17 to 21.5
Yes, squared law applies on speed related drag, so 10% speed reduction means only 81% of the drag. The man is generally right and yes, miracle magnets or other snake-oil fuel products do nothing for calorific value. Sadly, tailgating has a huge beneficial impact on fuel consumption, but promotes collisions!
Wonder what kind of fuel economy you'd get with an electronic 7.3 IDI.
By "electronic 7.3 IDI" I mean a 7.3 IDI with an injection pump but controlled by an ECM and solenoids instead of a mechanical rack, governor, and check valves.
@@electric7487 I've thought about this before, but one of the beauties of the IDI is it's simple and mechanical, and therefore incredibly reliable. Still I'd love to see one with modern injection and pumps, an ECM and modern features like injector shut-off on deceleration. Probably bump those numbers up to 23-24 mpg. Pretty incredible for a 40 year old diesel engine displacing 7.3 liters. It's funny, my buddy's with their modern 7.3 powerstrokes average 15 mpg, albeit more power.
@@Taydrum I just found out that Caterpillar are using those distributor-style common rail fuel pumps on their C7.1 and C9.3 off-highway engines. Seeing as to how the IDI's fuel pump is also a distributor-style pump, I think a common rail system would be better for a new IDI as it makes everything much more compact. Also, I'd like to see spherical swirl chambers like the ones shown in chris.chemidl.in/wp-content/uploads/2014/09/1.005.jpg
@@electric7487 Definitely a good place to start, however I know these things get complicated fast. Probably runs a different fuel pressure range, and the IDI stock injectors pop at a pretty low pressure. Would need newer injectors, and that would probably affect the timing. I believe those are also 6 cylinder injector pumps.
I love that your actually discussing engine efficiency.. no one is dissecting this anymore
slowing down is what I do to save with heavy loads, usually when I pay for fuel. Brakes dragging could be a reason for a sudden drop in fuel economy. All excellent and complete methods.
I think driving speed is a significant factor due to drag. The first time I had driven through Utah and Nevada in our diesel pusher, several semi trucks passed us on I-80 driving over 70mph. Since I live in California, observing these trucks flying past us was shocking since the speed limit in CA for vehicles with over 3 axles is 55mph. Needless to say, the fastest I usually drive our 34' diesel pusher is 65mph.
Just found this video and I have to say this is solid good information without any bullshit. I’m just driving a 2002 7.3 liter diesel in my F250, but I’m sure a lot of the tips translate. Thanks for the info and I’m definitely subscribing to your channel!
Another superb video, Josh. I would imagine all your followers would gladly watch the 40 minute version.
Your math is just fine, but 5 mpg to 6 mpg is NOT a "small improvement." It's 20%. That's a huge improvement.
True, but easily achievable just through driving habits
I really like your information on the cat motor. I bought a 2003 model c-15 and really like it, and I enjoy the education I get from your shows.
The bicycle question delivery gave me a good chuckle.
No free lunch anywhere. I have run 60 mph everywhere, minimum idling, back off on the hills, little throttle on acceleration and made top fuel economy in a small fleet of 200 trucks. I didn't really try for this. The data sheets came in and that was the result. I did this more than a few times but mainly did it because of fuel cost.
Kenworth T600, Cat 425, 18 speed with tall rubber(24.5).
Thanks for covering the DPF part
Excelente información!!! keep up the good work my friend over 35 years trucking and I’m still learning something new THANK YOU!!!
Great information. I have a 1981 Mercedes 240d. The has answered many questions. I use Amsoil synthetic diesel oil for Classic diesels.
Find out how much the timing can be advanced on those. I think it’s 24 or 26 degrees max. That really helps fuel economy from what I hear.
+Adept Ape Love the videos and the information as always. Thank you very much.
Great videos, busting a lot of the myths around engine maintenance and mechanics.
Biggest fuel savings I’ve ever had was disabling the stupid 4-cyl mode in my V8 Silverado 1500, and having it tuned. Plus it drives a hell of a lot better. Anyways I think for OTR diesel applications driving style/ speed, and not idling for long periods of time are the biggest fuel savers!
You're the man. Keep up the great videos
Great advice as always thanks for sharing your knowledge
My (local/hourly) quad axle dump, 2006 KW with CAT C13 ACERT with 4:10 gear ratio.
I shift @ 1500 RPM and I use my Jake always.
My MAX speed is 60 MPH @ 1500 RPM.
I keep up on my tire pressure weekly.
Very good video, always think you do great job describing things!
Maintain proper tire pressures.
And convert to super singles.
Chad Jessup never, if I ran local I would consider it but they are still to hard to find in rural areas if something happens.
Chad Jessup however I do run Alcoa ultra one rims with Bridgestone M710 drives and Michelin xline energy steers to maximize fuel economy the best I can. I also run the lightweight steel drums, it's not cheep to run efficiently but I was getting 6.8mpg pulling a reefer with my 96 international coe so imo it's well worth it.
That is pretty decent fuel mileage.
That's an Obama/ Biden philosophy.
Great video, no B.S., and very informative, I couldn't disagree with anything, absolutely first rate.👌👌👍👍
Thank you for your great videos!!!
In my experience the biggest factors in reducing fuel consumption are, reduce speed, less acceleration, correct tyre pressure, aero improvement, keep to maintenance schedule and anticipation to minimise speed changes etc. Reducing speed and how fast you accelerate have the added benefit of prolonging engine and transmission life, and time between overhauls. If you thrash it you trash it.
Great graph. Very legit looking
Efing good advices bro. Thanks!!
aero dynamic wereout for me unless I was running empty pulled an rgn 7 axle setup most of the time the difference between 65 and 70 was half mile to a gallon Lucas fuel additive after running 90 with and 90 days without worked out to 2/10 a mile gallon better with proper tire pressure makes a difference. also tires last longer and have less tire problems it all counts in the end
you and buddy have a good day
THE GRUMPY BUS
Higher compression means better fuel economy, and this means changing oil, making sure the rings are not worn out. etc.
Lots of interesting information.
Really appreciate your knowledge ! 👍🏽
Thank you very much! Very informative!
Thank you. You make everything look so easy. I'll apply all the advice to my C-15 engine.
By the way excellent program today super fantastic commentary,,,gentlemen let's also not forget just in case you have a dragging brake make sure the rear ends full of grease driveline is greased front wheel bearings are greased ...tire pressure of course
My son has a KW T800 C13CAT 475 it has 1.500 million miles and still running good no blow by no oil leaks hardly uses any oil after 15.000 oil change. Great fuel mileage my son takes good care of his truck he uses Mystick oil and lucas additive in his oil and fuel
Great video! Thank your!
I really enjoyed the 7th injector part.
I have a FL70 Freightliner and regularly got 10mpgs...one of the things I do is to always take my foot of the throttle if I see a red light down the road...just coast...saves brakes, clutch and fuel. Sometimes you don't even have to stop and start...you just keep moving...
@AlzWorld57
Yup. That’s one of the biggest inefficiencies you avoid there. Stop/starts are a killer. My car gets 60mpg but traffic lights put it down to 36 average.
One fuel additive that does what it says is Enerburn which reduces soot and increases my regen interval a lot. There is a similar new product called BetterDiesel FBC that does the same and includes injector cleaner. My regen interval was about 350 miles and is now about 500 miles.
We have a stretch here in Tx (SH10) and the speed limit is 85. Drove through there once and it was strange feeling my silverado bounce off the rev limiter every few minutes with that stupid 96mph or whatever limiter GM has or had?.. Anyway good stuff man, keep em coming!
I remember learning to run the engine down to peak torque in an old series 60 class back in 2000. If you've never ran out under load that low of rpms you may think it is breaking your engine because it sounds bad, but it does bring the fuel mileage up and didn't seem to hurt the longevity of the engine. Great video, thanks for the content!
Excellent info. Don't worry about the length, when it's worthwhile people will watch. 👍👍
Took a minute to figure out what you meant. I didn't even think about the video being kinda long, I suppose. It's kinda a complicates subject, so obviously deserves the extra time and explanation. Basically common sense, but then again that ain't so common these days.lol
Great video Josh. Stay safe and healthy Sir.
Well explained Josh. A formula 1 motor is a good example of high RPM in a small displacement engine giving high horse power. They have low torque hence need lots of gears and lots of skill from the driver to keep the car in the power range. They are also very high tech and have a short and expensive life. Horses for courses. Jeff
thanks great job
Good video
Drive at a steady speed, and in the the correct gear, lightish throttle loads,will make a difference with
Economy.
Big things on a 425b, valve set (not cat spec) advance injection timing and smaller exhaust manifold to get you turbo boost up higher, and propane injection we have two doing consistent around 7.5-8 mpg loaded
Cool! Does the propane replace diesel use 1:1, meaning you save a gallon of diesel and burn a gallon of propane? Or is the propane more, or less efficient?
Hear anything about water injection? I’ve heard good stuff about that.
you so humble and smart man thank you
Aerodynamic resistance is the the speed squared ie double your speed and you burn 4 times the fuel. Also tyre pressure makes a big difference and the make of tyres. Tyres in the UK have a energy rating, wet weather breaking and noise markings on them to help you choose.
I got two words for you, preventative maintenance.
Hey there. Totally diggin all your knowledge! Thanks for sharing! You have zero idea how much YOU help people like me learning diesel (CAT)! I am running dual CATS 3116’s in a marine environment (Knotty Hattitude). I did not see anything about cold condensed air via intake to increase fuel efficacy increase. Obviously I’m knew to diesel and have zero clue, lol. Wondering if I can get better engine “room” circulation will this increase efficiency in anyway? I guess Im asking if colder condensed air makes a difference in fuel economy for Diesel engines? Btw SW Florida here. Engine room is not sealed, but no forced air mechanism in place just KnN intake filters on engines.
Hhhh he
So good. Hello from Russia🖐🏼
Hail the Ape with immeasurable knowledge....Respect.
I figured some of this on a 40’ motor coach. I drove for two years at 60-62 mph. I improved mpg by bumping speed up to 66 which put that engine in max torque range.
I did a thermostat to raise engine temperature in my 1997 F-250 with the 7.3 L turbo
Also you can play with the ratios of the truck, like double overdrive.. (inverted gears) and lower the axel ratio, like from 411 to 355. I'm talking because own experiences. Mine a 1995 wia volvo m11 reg 10 speed and 411 rears. Switch the transmission to a 9 inverted and 355 rears, went from 6 mpg to 8.5 mpg. At 72 mph im at 1200 rpms.
Few Ideas I had watching this
- You mention jake brakes. They would increase fuel economy if not using air?
- Alignment of the wheels.
- Mirrors. Are cameras legal to use?
- Drain on electrical, lighting, accessories, does it make a good difference?
- Are there upgraded turbos that would be more efficient?
- Misadjusted brakes or bad wheel bearings.
Well done! , Got anything for my Gen 5 , Cummins 6.7?
well, using the jake brake does technically increase MPG, since you literally do not burn any fuel for the distance travelling with the jake brake on, plus it reduces brake rotor and pad wear
Dropping from 65 mph to 55 mph is huge.
I agree it's very huge, but I find I can't run 55, even though I'd like to, because of time limit, and traffic jams.unforseen setbacks that will make you miss appointment times.
Aaron Garcia my Freightliner got close to 3/4 gallon better at 68 than 55. Gearing has a lot to do with it. Fleet trucks are specked incorrectly. Cheap cookie cutter trucks.
Well at 75+ mph my 95 powerstroke drops rpms, 4th gear. Below that it's 3rd and 2400rpm
BINGO!!!!!
Seems to me manufacturers could install gearvendor type units on the 1 ton and under trucks and we could all save a ton on fuel costs. But that would cut into CEO salaries and we can't have that now can we.
More hp and torque with a taller gear can be more fuel efficacious. Depending on your mode of operation
Scania 16.4 liter diesel produces full 740 horsepower at 1300 rpm and holds it to 1900 rpm. With max torque around 2700 foot pounds at 1,000 and holds it across as well. Sounds like a great city/highway engine to me.
Yes, but, and there is always a but. A lot of roads in Scandinavia, do not have 100 kph limit, so your not getting into the aerodynamic wall (air resistance going up with the square or cube of speed over 55 mph/90 kph, at which point it overtakes rolling resistance). Those engines are mostly spec'd for their heavy haul.
Hey Adept Ape. I just came across your channel. What do you think about this new fuel additive from Diesel Force and their DPF cleaning system?
Here's your automatic thumbs up.
Automatic, I thought I earned those thumbs. I'll take them either way though.
Adept Ape INDEED. You did earn it...automatic 'cause I still haven't found one of your videos to be a waste of time out of the many you already have.
I think a lot of people will gloss over the fan concept and the amount of power they can kill. First off yes I know the demo is on a gas engine but remember the equation for HP doesn't change (=[RPM x Torque]/5252). Watch Engine Masters episodes 20 (fan) and 35 (accessories) on motor trend, since they removed them from RUclips.
Thank you for making these videos, I'm learning a ton.
Yes. Torque is the real number, hp is calculated.
I knew two guys that ran together, same truck, same engine, same loads in all kinds of terrain, souped up 350 Cummins and 5x4s. Only difference was one had higher speed rear ends so he could cruise in 5 direct instead of over. With the power going straight through the transmissions in direct instead of the counter shaft in over he saved 10 to 12 gallons a day over his partner. These were bull wagons on mostly local hauls, so they were not driving high mileage. For a long haul trucker on mostly flat ground, I would expect more difference.
No this is another very important thing an old truck driver taught me there's a magic spot on the accelerator pedal and any less pressure on the accelerator you slow up the tiniest bit more pressure on the accelerator you maintain speed but beyond that,,,, any more pressure on the accelerator with no gain of speed is wasted fuel so always calibrate your foot to the speed mean and don't have your foot just stomped on the floorboard going the same miles per hour back to foot on out of the accelerator,,, and match it to the exact speed and load
Thats interesting
Do you have any experience with Archoil products? I've had good luck with their oil additive improving injector function on HEUI setups especially on cold start.
Good info !
Damn good video.
Damn good.
From the stock tune. I had my 1998 detroit 60 turned to 700hp and I seen gaines up to 1.6 mpg better😁👍
Good video thnks
Where did you get that awesome hat? Great video, thank you.
Thank you for all the advice I just bought a cat C15 acert twin turbo 2006 are they known to be good engines are there any problems I should be looking for
Biggest improvement to a CAT is a GOOD aftermarket tune. All the CAT tunes are now low NOx tunes ...which reduces the injection timing. Years ago I drove an 01 Classic XL with a 13 double over and 6NZ that had new injectors done by CAT but they also flashed the computer for free since it had never had a reflash since new. With 4 new injectors it went from 5.9-6.2mpg to 4.8 to 5.5mpg and had the most unhappy sounding 550hp ever. The owner got frustrated with the truck and sold it for an ISX Volvo auto. I wish I knew then what I know now and purchased it from him.
Yes, you know this and I know this, but most people don’t.
EPA makes you waste fuel.
All these “experts” speak their THEORY that “more power means more fuel”. They need to stop talking since they don’t know.
The fact is like you say, proper timing and fuel delivery for EFFICIENCY, not for EMISSIONS.
I'm an Old Farm Boy and we ran Fleet 1540 in all the fleet from the Ford Ranger to the 350 horse Cummins do the D7 cat,,,,,,,, and I never shut engines down I always let them idle,,,, now in the Ford Ranger I discovered when I went from sleep 1540 to synthetic 5w 30 I gained two and a half miles to the gallon,,,,, all my equipment has very high hours and miles on them so running thick oil really made me feel good,,,, but recently I found out on the smaller engines going to 5 W 30 synthetic I've wasted thousands and thousands of dollars in fuel over my 30 years of being a driver operator,,,, I don't want to even think about how much money I wasted I never had an engine go bad but I wasted a lot of money on fuel and gas,,,,, so now I am trying to run lighter oils and smaller engines,,,,, and since I've never had an engine go bad now I'm shutting them down whenever I can so they ain't idling,,,,, just my observation thank you
Well as an engineer compression ratios are critical to running an efficient engine along with preventing friction losses and energy into heat loss prevention. Gear is critical to, but namely for diesels 14:1 -22:1 is the sweet spot for compression ratios depending on fuel delivery.
You've got some interesting videos mate
Hey Josh. I'm a fellow Cat truck technician here too! Nice video and full of good information. Lately we have been getting dinged on warranty from Cat for owners having aftermarket software and "hopped up fuel injector codes". Perhaps you can use your channel to spread the word about the subject on changing software and Caterpillar's reaction to it. We are a relatively small shop in the big scope of things and Cat has been really cracking down on warranty claims using the warranty report information against us and I feel that we need to get the word out to the owners that this is happening. We have been denied four times for a total of about 10K worth of parts and labor that we are now having to have the hard conversations with customers about, so any way to spread the word around about another danger of "hot software" would be a good subject to talk about. Really enjoy your channel! Keep up the good work!!!
Not sure if I'll make a video on it, but yeah you have to watch for any sort of fiddling with the fuel system at all. Cat is bad about training their mechanics and warranty people in general from what I've seen.
I run a 74 A model kw with a 400 hp big cam set up at 525 to rear wheel hp. Prefco 212 injectors, 12 button, purple spring with A ported Pulse Manifold and a Holset 4 series turbo. 13 speed with 370 rears. Absolute ground pounder at 48 lbs of boost. Averages 5.7-6. Driving responsibly. Our new petes aerodynamic trucks are getting 5.2-5.5. With 40 plus years of technology I’d say we’re not that far ahead honestly.
Actually we are “farther ahead”. Just the agenda has changed. We are farther ahead in reducing NOX gasses and couldn’t give a damn about fuel economy or power.
on my 2.5L TDI Van when the conditions are good it gets 25km per liter
I drive conservatively, accelerate slow and I press the throttle as less as possible when I'm at top gear
my top speed is about 60-90kph seems slow but that is considered "fast enough" to not cause traffic in the Philippines
Could you explain about ECM working and also troubleshooting process
Can you put turbo on any diesel engine without changing engine parts apart from exhaust manifold. Talking about a tractor engine here.
I took a 96 classic with a 475 Detroit. Swapped injectord gateless turbo advanced timing 13 single od 3.07 rears with 11r24.5 truck ran an avh speed per gps of 70 and was getting 7 mpg. Every truck i have owned or setup for people got better mpg with higher hp settings normally 550hp. More power more torque. Allows you to pull better on hills and get back off the fuel.
Where you are really picking up the mpg, is the 3.07 ratio. If you aren't pulling heavy haul. It works great, just have to keep to the manufacturers recommended minimum rpm and not go below (danger Wil Robinson, danger), some flat-landers would try and pull a higher gear getting into a big grade, pulling max power at low rpm, do that enough times and I believe the cylinders will be dancing in the block before long.
I'm more of a Cummins engine type. Grew up with the Big Cam III & IV. I like Cat just never ran them. Two friends ran them, one worked great, the other, the engine nearly broke him, he still has it 30+ years later, and uses the truck for hauling his excavator around.
Best wishes from the far North.
Dropping speed from 75 to 55 will definetly help a lot with mileage, but from my own experience, keeping the engine on the boost at all times is what helps the most.
I have a rather new 1 Ton Mistubishi 2.5 Diesel Truck. It gets the best mileage when I drive keeping the Engine Speed above 2000 RPM. The Turbo in that engine operates from 2000 to 3800 RPM. Driving under the boost curve, it will feel sluggish and consume more fuel than when using the whole RPM range. Just my 2 cents.
Great video you have helped me a lot just giving me some knowledge and I have heard that some people are adding 2 cycle mineral oil to there fuel for injector lubrication what's your opinion they say it help cause of the low sulfur fuel thanks again for your videos
I lost fuel mileage adding 2stroke oil. Same with trans fluid
The main reason aero loading matters so much is that drag is proportional to the square of the speed. Double the speed, drag increases by a factor of four.
More than that the faster you go.
The cetane ratings very wildly at different fuel stops. You need to pay attention to differences in your fuel mileage and remember were you got the good stuff at.
Engines running at lower rpms will notice cetane ratings less and you can buy cetane boost to spike it.
When I used to drive a truck it wasn't that big of a deal, but now that I own a diesel at home with a smaller engine you do really notice big differences when buying fuel at different places.
I found Mobil got my powerstroke best mileage
I don't know if you're aware of it but maybe you heard of water methanol injection. I have it on my truck I had it on the previous truck it helps fuel mileage significantly in my opinion because it increases torque by approximately 25%. it only works when you're pulling a hill. the water is injected into the intake manifold and a very fine mist it does two things it helps to cool the intake charge so you get more air in your engine and it turns to steam when the fuel Burns. it also removes a significant amount of heat from your engine. my exhaust gas temperature typically Run 200 to 300 degrees cooler I have found that I can lug my engine at a lower RPM without burning out my turbocharger. also when I look the engine at lower RPMs the steam pushes the Piston all the way to the bottom of the stroke. most people don't realize it but by the time your piston is down 120 degrees after top dead center you've extracted most of the energy you are going to get from that charge. the steam in the cylinder pushes the Piston all the way to the bottom steam simply doesn't quit pushing. snow performance has a very good system. I have a 15 liter cap right now my last dungeon was a 13 lb cat. that 13 liter cap on factory settings out pulled a 600-horsepower cat coming across California we were both running 80 thousand pounds and I don't pull him on Every Mountain grade with a stock 13 liter engine. I'm sold on it I don't even run methanol I run straight water it's very beneficial for an engine properly installed properly operated it will not damage an engine
Reed Silvesan which system did you go with? Thx
@@bctw9004
"...snow performance..." (?)
Best thing that I've done for my Ram Ecodiesel= GDE Hot Tune! Getting 31-33.5 mpg now! Dynos way more hp and rwtq. Still never smelled as clean a motor under full load on the dyno! Raising cetane with CenPeco additives did nothing for mpg.
Tune/advance timing is where it’s at.
Hi Josh good info. I run a Iveco cursor 8 330hp just 2 axles with a heavy 3 axle trailer. the other guys in the fleet run about 2.1-2.3 kml. I run between 2.8 - 3.15kml. took your advice about low boost pressure made a big difference btw. I can agree with you about the leadfoot thing I stick to around 85-88 kmh. 1 other thing I can add that does make an improvement is the distance of your trailer from the back of your cabin. I had the 5th wheel moved as far forward as was practical an makes a significant difference. now I'm running a dedicated trailer Curtain sider. would lowering the viscosity of gear/diff oil make any kind of difference? I live in Brazil btw. where we pay around $3.09-$3.25 per liter. Thankfully after we paralysed Brazil for 13days government caved in and gave a reduction of 0.46c l. Add this figure to that above and you get a part of the real cost! My boss pays $4.5-5 million per year on fuel. on a 30 truck fleet. It's taken about 3 years for him to finally start listening to me on ways he can improve his margins. Decrease costs etc. That's just by leading by example. The rest of te guys in the fleet are gradually getting the message through their hard heads. 2 thumbsup and keep up the good stuff.
Lowering the viscosity of the oil in your transmission and differential will improve your fuel economy, but not by much. Less than 1 percent probably. Also, if you use a lower viscosity oil than recommended, you risk causing damage or excessive wear, so don't go lower than what's recommended for your truck. Hope this helps.
I definitely agree on closing the gap between trailer & cab. Your breaking wind once, not twice.lol
Great vid
very good
Thanks for the informed opinions Josh!
Do you think that fuel polishing is of any benefit?
Fuel economy, injector and pump longevity improvements?
Keep up the good work man.💪
Number one thing to do to increase fuel economy from a good running engine is
Use your cruise control
Detroit Diesel for one programs driver rewards by way of increased hp and or higher road speed ( this is more common for fleet trucks)
Reason being as in cat they have soft cruise that lets the road speed drop a little and increases throttle lightly Kind of like the old saying put a egg under your throttle with out breaking it
Also if equipped with progressive shifting
Or not practice this shift early dont wind out your gears use the torque range of your engine
Peterbilt Mack Cummins Detroit Diesel Catipiller Mercedes Benz factory trained tec 37 plus years Retired
you are very wrong Paul, if you use cruise on flat level ground yes but when you sstart running hills get off the cruse
You are correct, i really dont know how to translate this to miles, but i drive a Hyundai i20 1.4Diesel, it's got 220nm round 1750-2500 cruising at highway speeds, the rpm is like 2100rpm at 120KM/H and the fuel consumption VERY low... I get use average 5L/100km 😊, and its punchy. What do you think is the lifespan of these smaller Turbod diesel enjines? Its at 150000km now 2014 Model, and haven't had any issues whatsoever...
I drive a 2018 peterbilt 389 glider & pull a stepdeck. it's got a '99 model series 60 12.7L Detroit @ 500 hp. I drive this truck between 1500 & 1700 RPMs (when loaded) & typically drive it at 18-19 lbs or less of manifold pressure. I drive as fast as 18 lbs will get me. as fast as 75 & 80mph quite often. most loads are almost always either heavy or drag a lot of wind. the worst I've done on a tank of fuel is about 5.8 mpg, but typically avg between 6 - 6.5 easy. we run 48 state.
THOSE ARE GREAT MOTORS.
13:45 As a cycling truck driver, I thought the max bicycle speed was 70mph, had no idea they had gotten up to 83mph, funny where the you find things out.
I believe the record is now 89 MPH. Also a velomobile.
Hi Adept Ape, on a modern 4x4 turbo Diesel engine Would a oil catch can be beneficial or are they a waste of money?
Does adding oil just reg 30 engine oil help you engine.. i feel it better when i do it every 2 weeks.. C15... good video.. I 👍🤘
