I owned a mid 1990s Toyota Hilux ute that had 545,000kms when she finally died. Oil changes, brakes, air-filters, and the odd battery is all I ever had to do.
My mechanic bought it off me, chucked another engine in it, and she's still running, apparently.
Toyota know how to build utes.
I have a Fiat Panda 4x4 from 2008 with the multijet, 280.000km and still running great
Nice video. I watch a lot of videos like this. New or used, buying a car is getting very scary..
Yeah- especially with the prices of fixing- or trading - to brand new - I got 26.,000 MLS on my elantra2020- & because of the extra car ins.- (added warranty ) - - it makes trading look smart.... til you see the% rate to finance new 2025
I'm old school. I don't care what they say, I change oil and filter every 5k. Call it cheap insurance.
I worked on Busted Motor Works in the late 70s. 50 years later, nothing has changed . They're still figuring out ways to overlook the obvious in the name of improvement.
In your expert opinion would using an additive such as Risolone or Marvel Mystery Oil possibly extend the life of the oil?
@@jamesmitchell1780 NO. If you use an additive like that in your oil or any other then you're not using the right oil/not a good enough oil. Always,always use good oil with a decent filter,never the cheap ones. Here in the UK many use low quality oil & low quality filter which is not good even for 5,000 miles! Keep doing that on each service over the years then engine will not last. Many owners here want cheap motoring but regrets it when the timing change fails or other issues happen. Many car part stores sell cheap filters here. Good oil & filter no more than 5,000 miles is my strong advice or you'll get sludge & piston rings issues....then the catalytic converter gets all that bad stuff through it!
Every 5k so for me every 2 months. Waste of money and oil.
I do the same No problems with eco boosts in several vehicles.
oil is cheap engines are expensive
I guess I'm fortunate. I have a 2 liter Ecoboost engine in a 2013 Ford Fusion. It has been so reliable. 250,000 km and still going strong. I change the oil with high-quality synthetic and use an equally high-quality oil filter. Oil changes are done when the automatic indicator tells me to do it. The other thing I've done is make sure I use an oil flush additive before each oil change. I've been happy with the car.
No mention of Land Rover Jaguar, Ford eco-bang engines. Also Rover K-series engines which were 💩
True while some EcoBoost engines are crap, if you take reasonable care of most of them, they can last a very long time. Case in point, my brother in law’s 2015 Focus ST just turned 595000 miles with the most severe repair being a water pump replacement at 282000 miles. It has the original turbo and clutch.
@@tiberius1701 I agree, servicing is most important as with all engines. The trouble is when you put a small capacity engine into a large vehicle. The poor little thing is always under stress.
@@tiberius1701 Have you got an extra '0' in the miles quoted?
@@iamspock Nope, 595000+ genuine miles.
I worked at an oil change service center. We had many Northstar motors come through with 400k+ miles. Just have to stay on top of the oil changes.
@Spymell Depends on how well the motor has been maintained, the quality of oil in it, the environment, and your IQ. Judge oil change intervals on oil condition rather than mileage. The book probably says every 6k to 8k miles. Treated properly, you can easily go 12k to 15k between oil changes. Drive it like an idiot, and you burn a quart of oil with every tank of gas.
Just sent my 2000 SAAB 9 5 to the junkyard.
Had 300000 km on engine and automatic transmission - no trouble ever!
Frequent oilchanges with syntetic oil.
Never owned a car that long.
Body rusted away.
I used to own SAAB 95 2.1t similar engine like in the video. I had an issue with the automatic gearbox = Expensive. Otherwise great car. The seats were super comfortable. At the end it was written off by idiot driver on drugs who rear-ended car and three others.
BMW n52b30 256k. best ever 2006 530xi. Still drives so fine.
This is a very misleading video, as a mechanic i can tell you that some if the engines described as bad are completely opposite, the 3.6 pentastar is a pretty decent engine, I've seen several of them with over 300000kms, the 2.0 l ecoboost is not nearly as bad as the 1.5 and 1.6 ecoboost, I've seen lots as well go well past 300000kms, this video is wrong for most of the engines listed.
Yeah, just the same with the Alfa Romeo 2.0 engine. Propper maintenance and it will last very long.
This video is showing the older SAAB engines. The later 2.0T Ecotec engines are very reliable with timely oil changes.
Experienced plenty of Pentastar 3.6 liter engines with valve train issues. Experienced the timing chain and guide issues with BMW vehicles and GM 5.3 engines with collapsed lifters. Nissan CVTs are also a total joke and dealerships have rows of them in the shop for potential swaps. Many modern cars on the market are less reliable as they are forced to engineer engines that prioritize strict emissions standards set by the EPA over performance and reliability.
All problems with the DPF are related to the driving style, no one warms up the engine enough to start the regeneration, because they drive short distances, you don't have to get in the car if you can walk a hundred meters
This EW garbage is ideal for such owners, and even better when the cars become smarter than the owners to maintain themselves.
Thank you for this video, but you forgot the Range Rover engine 😂❤
every JLR is unreliable heap of junk
Nothing wrong with Range Rovers, until they go to America, where their mechanics have neither the knowhow or sophistication to look after them. Nobody buys american cars other than in america, because they're terrible.
Oil and oil filters are the killers of engines.
Just change the oil with fully synthetic oil and oil filter every 6,000 miles.
I think that the FIAT 1.3 Mjt engine is one of the best little diesel ever built.
The issues were concentrated only in the very early productions...
I had 2 twinspark engines of Alfa romeo the 1.8 wich is the same as the 2.0 only the 2.0 jts are different. But the regular 2.0 and 1.6 and 1.8 are very reliable. Just do regular oil changes and indeed warm up the engine and they last for a very long time 300.000 miles is no exception.
Great video! I watch plenty of videos like this. Whether new or used, buying a car has become quite a nerve-wracking experience...
Give me a 225 slant 6. Them things were bullet proof.
I can't believe that the automakers are allowed to put these junk cars in the showroom, they do this intentionally because they make money to repair them or you're forced to waste money buying a new car...planned obsolescence again
Would you buy a car without a brand? They are using their brand as an icon of reliability. The only question is who's gonna take the bait.
This is a very good list of future eventual lawn ornaments 😂😂
Who waits to change oil for 9000 to 30,000 miles? Asking for trouble if you don’t change oil and filter every 3,000 to 5,000 miles.
Dont chintz by using 'economy' engine lube oil.
Standard recommendation for EVERY engine made after ~2010:
If 90% of your driving is at steady state (cruise control ON) change the oil AT OR BEFORE 2/3rds of the mgr. changeout recommendation.
If the preponderance of driving is short interval 'stop & go' (city) driving, change the oil at HALF the recommended interval.
The cost of 'early' oil changes is significantly LESS than an engine 'rebuild' or replacement ... or a new vehicle.
THE PROBLEM is that most engines is the use of LOOSE enginepiston rings that foster LOTS of engline blow-by of the combustion gases past the piston rings which DILUTES the engine oil VISCOSITY. over time !!!!!
I changed oil one time,on my Lexus ES300, in 4 years. It was good until I sold it. It had 200K miles
Right, what idiot waits to 20k? Oil is sludge by then.
I know people who have dual overhead cam ALFA ROMEO 4-cylinder engines with over 200,000 miles on them that have never been rebuilt. As far as oil is concerned, ideally you have to use a 10w50 oil which is near impossible to find in the USA
PSA or for ecoboost engines with wet belt are a nightmare. Audis old v6 tdi had a camshaft problem, but it accord after 100k.
The Caddilac Northstar engine is not as bad as people make it out to be. I bought a Caddilac STS from a drug auction and I put it on the road as a taxi. It held up surprisingly well with proper maintenance. I drove the car an average of 3,200 miles per week for 6 years before it was destroyed in a crash with a drunk driver. I was very adamant about the maintenance being done on the car. The oil got changed every Friday and the transmission was serviced every 50,000 miles. The main reason people didn't like the Northstar is because they were too lazy to properly maintain their vehicles. By properly maintaining the engine my STS had over 700,000 miles on it when the crash happened.
El Renesis gasta aceite porque funciona de forma similar a un dos tiempos, no es un fallo, simplemente la lógica de funcionamiento de un rotativo.
Skoda 1.2 htp euro5? Creo que lo confundes con el 1.2 tsi, y más cuando se ve la culata, el thp era un diseño pre-Vw con 2 válvulas por cilindro.
Y por último, te dejas el motor más problemático en los últimos años! El Puretech de Psa (o Stellantis, como quieras)
Y otro muy problemático, el Ingenium de Jaguar/ Land Rover
Cool list, and useful info, but when I got halfway thoughout the video, the music beeing the same was too much for me.
What a bunch of nonsense and untruths spoken in this video.😱😱😱
Yup, total shit
About VW 1.2 TSi, before 2013 the EA111 engine was truly problematic because of all the trouble regarding the timing chain and tensioner, after 2013 (when they replaced the timing chain system with a very robust Continental timing belt) 1.2 TSI EA211 version, especially 90 HP one, is one of the most long lasting and reliable VW gasoline engines ever built.
22:25 why do you show a vintage ALFA ROMEO GTV(1963 -1978) when report on the 2.0 Liters, 4 cylinder Twinspark engine. That car “NEVER” used that engine.
My Mazda made it to 95,000 miles as expected for the rotary engines. I liked it a lot and had it overhauled when they did work like this back in the day. So, I call this video BS. Because my friend also had the same sports car and hers lasted 91,000 before an overhaul. She loved the power and the smooth-running engine.
At 0:39 you summed it up. "it's all about power".
If power is all you want it's all you're gonna get!
the engines quoted with high oil mileage changes is due to specific euro oils, which have very long life. If you live outside the EU you wont get these oils easily due to price and many factories just want to manufacture their lower quality oils. the reason for euro standards is environmental, as longer lasting oils means less environmental impact. SInce other countries dont care the oils you get there dont last long so you have to change your oil more frequently. Different oils have different ages. Also if you idle that counts as miles too.
Ofcourse there are a few BMW examples.. but honestly, I thought there were much more BMW examples in this video.. Not to mention the last couple of years with their latest “designs” wich undoubtably the pinnacle of bad taste! And it’s just a matter of time that they fill this kind of lists to the brim..! Mark my words… 😏
Based on what? Thin air? B58 has been out 9 years out and some have 250k miles without any issues the video above is talking about. Okay some B58's fail but that's rather on the person owning it then the engine, some tuners are ridiculously bad.
My saab 2.0 was 156282 miles when i sold it.. And i sold it beacuse turbo was bad, now 4 years later.. Car is still registrered and running in another city 😉
Why aren't I surprised that BMW is on this list...Broken Motor Works
Broke My Wallet
lol, the v6 tdi does have camshaft wear, but usually at 500k, not 35k
the Northstar? Most of those early ones blew up a looooong time ago, until GM "fixed" the head gasket issues (2002ish).. when have you seen a Cavalier/Sunfire? I have a 1989 grand am quad 4 with 185,000 miles.
The teaser pic shows a Range Rover Sport but I didn't see it in the video?
So what you're saying is we should buy a horse?
Just buy a Toyota
@@KiranKumar-uv6kdnope, their trucks and carolla are shit now too
A downloadable list of engines that suck would have been very useful and required a lot less time.
I'll stick with my 2013 Mini Cooper 'S' Roadster R59, with 23k miles on the clock. Still goes like smoke(less).
🤣😂😂
Interesting. But why does this video's thumbnail show a Range Rover Sport never mentioned in the actual video?
I change oil In My Renault 2.0dci every 10 000km or 6200 miles AND GET IT REGULARLY CHECKED. My advice? Take care a good care of your car and it will drive you to the horizon and Far BEYOND
Regarding the 2.5 TDI from Audi the problem was mostly with the earlier 155hp variant. The 180hp one had stronger camshafts and is pretty reliable. Is not uncommon to see this engine with over 350k km in Europe.
Add the Buick A14NET 1.4-liter 4 Cyl to that list. Valve train failures and oil consumption.
Can I get the name of that oil they're running for 30,000 miles in that Fiat?
actualy bmw has some great, reliable engines m57 for example
I remember Volvo, in the 1970's, tuning an engine down to enhance durability.
Today, they power up 1.2 engines to increase performance.
Don't be surprised if it dies early.
Surprised that some engines like the awful 1.0L EcoBurst and the post 2010 1.0 to 1.6L PSA rubbish engines + Renault Tce/ Nissan small turbo (1.2L) crap engines are not on the list.
PSA 1.6 engines went to acceptable reliability just after 2010, and went even better after 2017. However 1.2 were not a good choice until 2023, when they started to replace wet belt with a chain in the timing system.
I’m alarmed at how much BMW shows up in these sorts of videos. I don’t own one, but had a 320d as a company car ages go and liked it. I had the impression they were reliable.
OEM older engines from the said companies have this issues. since most of them like ford and bmw partnered with chinese, models ranging from 2019 up to present have solve most of their problem with added technology.
Chevy cavalier
Pontiac sunfire
Pontiac grand am
Are 40 yo cars
If you have one of them then it probably has more than 35,000 miles
My Corsica 2.2L had no issues for 50K miles, it was slow that's for sure.
Some of these are Japanese--it's not possible they'd be on a list like this.
Wonder if it's fixed if that filter is removed
Please... that background music is maddening!
I had a Fiat Punto 1.3 Multijet.... Fiat recommends oil changes at every 15k kms... Got it done and clocked 250000 with no issues at all before selling it. First Timing chain changed at 120000kms and second change at 210000kms... This engine shouldn't be on the list...
Starting from 2008 until 2018, this engine was the workhorse of nearly all diesel hatchbacks in India. This number is not small and thousands of cars were rolled out every month with this engine. All this because of its reliability. Vehicles even clocked 800000kms with no engine issues... This info is all there on the internet..Just google...
The Northstar engine is another gm mistake
Only the early ones
@@sounddoctor5decades True-when the head studs issue was fixed, they became very reliable.
I don’t know where they’re getting these prices because they’re about a quarter of the actual cost of what it would really cost to do any of these repairs.
I do like the 39000 miles but we have two vehicles a Suzuki Baleno not even mentioned in this video so it's done over 50000 miles still running well and my 1997 Toyota Hilux which has done 280000 miles still no issues obviously two well built and reliable vehicles well North America is missing out on Suzuki's reliability and the Toyota Hilux well at least you get the Tacoma and only buy the one with the 22R/RE engine
Tacomas have very good reliability in the US. I don’t know anyone who has issues with them and I have had one for a decade and I know many others as well . 300,000miles is not uncommon . . Close to 500,000km
and NOT A SINGLE Mercedes Benz engines in the list....
The 6.3 amg V8 is no picnic.
General Malfunctions
For an automanufacturer thats got alot of hype there are quite a few toyotas and bmws on this list. Hmmm. One Nissan,yet Nissan gets alot of hate. Maybe its the CVT debacle.
I'm not surprised that the mini Cooper is junk, it's a cheap BMW
This guy is obviously an ecotech lover ❤❤❤😂😂😂
So....
I guess the Ford eco-boost engines are very reliable??
They didn't make the list.
Most of these engines are not available in the United States because of the emissions standards required here.
Well the 5.3 liter GM v8 made the list 66k miles right now on the ole Silverado
Guys stop thinking about milage as a interval for oil change. Some people do 5k in 2 months or bus drivers in 1 month or even a week. Trip to Poland and back thats give you 2-2.5k miles so in two weeks you have that milage. I have to be an idiot to change oil every week or two.
There are some misinformation along the engines especially about diesels... Diesels require 5000-7500 miles for regular oil and about 10000miles for full synthetic oils recommended by manufacturers... Which are pretty optimistic recommendations...
Diesel engines by their working principle require more often oil changes especially if used in city traffic...
That is not a reliability issue that is how engines are maintained...
Same thing goes for gas engines or lpg engines...
Reliability comes in once regularly maintained engines failed due to production.
Any engine will fail if you use cheap and under qualified fuel with lots of additives, manufacturers cannot design an engine for the worst and expect it not to fail... :)
I had a neighbor who had a BMW and the engine needed to be repaired. He decided to do the repair himself only to discover that ordinary mortals can’t do the repair.
Rover's V6 engine didn't make the list then - prone to Head Gasket failure. Often Cheaper to scrap the car.
Kids on computers not understanding how engines really work is the biggest cause of engine failures.
I had to turn it off after the 4g yota engine. This dude literally took a list of failures on engines and averaged the failure mileage. Truth. The na N62 BMW engine is great. The Northstar can't keep fluids in it but it is very common to see 100k on a Northstar. Now the final. The renesis. If you don't drive the rx8s as intended, the engines last 40-50k and usually a little brake fluid solves that. Most go 80k+ before having severe issues and I've seen them go 140k plus. Last the 4gre. That engine is great the issue was the 10k oil change interval Toyota issued when the engine came out.
The fiat 1.3 multijet is one of the most reliable engines made by fiat and is used on opel too.
I think someone are confuse when speack of the fiat 1.3 multijet, the same block is used in the opel and is that modified engine by opel that is known for break very easy, because fiat when design the engine choose a complete group of periferic pieces and the opel took that engine and instead of go as the fiat, change everything with is thing and ideas damaging completly the engine.
Its the opel derivative who have the problems not the fiat one.
Had toyota d cat bought with 250k km sold it with 415k km... zero problems
Change the oil every 5k to 7k miles not every 18k miles lol..
I always changed my car oil every 12000 km, max 15000 km, my car's never broke..
An other thing to do is to heat up the engine before moving, never press the accelerator before heat up.
Had an older vw eos gas engine. Ate oil about 1 ltr a month easy.
Of course, all these engine problems go away with EVs-just to be replaced by other concerns and problems.
The only sound benefit of EVs appears to be that the drive-train technology was refined by 1890 and hasn't gotten much more complicated, despite Elron Mush's blather.
'Car Care Clueless'⁉️Saab developed technology found in most engines today including Direct Ignition (Distributor-less), anti-knock for lower-grade non-premium fuel (APC), turbo wastegate electronic control, and ignition spark control optimization (Trionic). Variable compression engine was going to be next... Most of this tech was about a decade ahead of it's time.
Those Cadillac "five eight" engines are nothing but trouble.
Man, I had to scroll this far to find someone smart enough to understand that the Northstar was a 4.6L. Except, when it was 4.0L, or 4.4L.
All problems with the engines can be traced back to the current gasoline where a lot of methanol is mixed to be better for the environment. What is not taken into account are the consequences that all environmental gains through repairs are nullified, technicians do not recommend 98 ron gasoline for nothing if you do not drive too many kilometers with your car
Drove that crappy Isuzu engine terrible mpg, no power with very little miles on the clock, told my boss to take it back I’ll drive my own car instead, regarding the Toyota 2.2 diesel can’t see any problems with mine goes through emissions easily every year 110, 000 + miles like every Toyota engine regular maintenance helps stop excessive wear
Sounds to me that manufacturers are making junk engines to force us into buying electric cars. Pleased I own and love my Suzuki Vitara.
No engine should ever have plastic parts that is why all these engines fail and why there isnt a good engine made today that will last.
Reliable car engines that die before 35k miles, what a contradictory statement..didn't listen as that alone put me off!
Add the gen3 EA888 to this list ... I was told it was bullt proof. I spent SGD12k on engine repairs and parts alone over 6 years of ownership
IS250 does not have diesel injectors :D
BMW would look great as a lawn ornament 😅😅, or being hooked up on a tow truck hahaha
Lately, many videos campaign against buying European cars. While the motive is unclear, car manufacturers should promote their strengths without criticizing trusted brands like Land Rover, Jaguar, Mercedes-Benz, and Rolls-Royce. These brands have earned global trust over decades. Focus on quality and let time prove your worth.
Mercedes W series diesel engines: I will outlive you and your next 15 generations
If you halve the service interval in oil changes your engine should last a lot longer, timing chains are not meant to last the life of an engine they to have service intervals of around 130,000 miles, most of this is BS.
1.3 mjet are super reliable... timing chain...so no issue until 200k at least. Fiat gives it for 250k km. Good performance and very good fuel economy
Gotta love my e46 :p
Where is this video getting the 18,000 and 30,000 mile oil change intervals? Even 18,000 km is an Insane distance between oil changes. For many cars, 7500 mile oil change intervals are too long.
So much to go wrong - an electric motor seems so much better. Though I suppose battery temperature maintenance adds a degree of complexity...
I have a 2015 Lexus IS250 F Sport with 176k miles and zero issues since owning it at 17k miles.😆🤦
Why on earth do manufacturers use plastic parts in engines? They're a failure waiting to happen. ALWAYS!
Fiat 1.3 mjet and Alfas 2.0 TS need oil change at 10K km
I can't find any Honda engines in the list.
I am using htp 1.2 engine skoda fabia which clocked 165000kms without any trouble,so in my case the videos claims are baseless.
Treble the prices for Australia.
Friend has a Juke with only24000km and the transmission has failed. Completely
