• Does Lucas Transmissio...
I have this 2007 Subaru Impreza that leaks oil from the head gasket. So I added some Lucas stop leak product to the engine oil to see if that would solve the problem.
You know your stuff, I'm surprised you don't have more subscribers. Everything you said was spot on and exactly what I have experienced. The transmission fix fluid I have never used in a car that was shifting horribly but I have used it in older vehicles as a preventive maintenance and it does indeed smooth out shifts but can cause a hard shift in extreme cold conditions. I have taken an engine apart once that was running Lucas in the oil and all the internals where sticky and coated in a film of oil, witch I'm sure would help prevent dry starts.
EDIT...Thanks for taking the time to upload my friend! I appreciate all your videos!
Thanks for this comment! I'm glad to hear someone else's experiences with the Lucas product.
I'm pretty interested to try the transmission product, as these Subaru transmissions tend to have issues with the solenoids sticking. Which is the exact thing Lucas claims to fix, so it would basically be the best-case scenario.
Also, my channel is not that popular because I don't upload frequently, and the RUclips Algorithm heavily punishes you for that.

I liked the correct terms you used for the parts and jobs required. Technical English at its best! Anyway, I drive a 1994 Toyota Camry. This product or Lucas stabilizer has been a must-added ingredient every time I make the oil change in the last 10 years and the oil leak is very minimal.

I have an external leak on an '09 Forester and was wondering about this product. I'm going to try it out after seeing this. Thanks!
Hi there, how did this work for your 09 forester? I've got a Subie 2009 as well and head gasket leak, wondering if it helped you. Safe to use?
@@brent462 I ended up just taking to the shop. My Subaru dealer cut my bill by over 50% after I told them I wasn't going to get it fixed. I suspect because they haven't been able to get enough car inventory the last couple years and are trying to get every penny from service they can. So it ended up being a lot less than I thought, and I knew the leak was going to eventually get worse, causing future repairs.
Just wondering what was repaired. Thank you.
I have a 2012 Impreza. 223k miles. Been using k-n oil filter from the beginning. Never an issue. If you use Lucas always warm it up before pouring in. It can work on some leaks and engines.
Thank you this was very helpful. We have a 2002 Subaru Legacy that has an oil leak. We took it to the shop and they repaired the valve cover gaskets but still leaking. Everything I read online says it's probably the head gasket but It's an expensive fix. My wife has already ordered a bottle of this stuff and we plan on using it. Will report back how it worked.
I've put about 2,000 miles on this car so far and still no leak. I'm pretty pleased for the price.
Thanks for the info!
@@keyleads2604 how’d it go
How did it go?
Yo any update?
Have this same problem with my outback. Thank you for doing this video
Very well done. I appreciate not only the information, but the method of communicating it. Obvious knowledge and the objectivity is welcome in a world of opinions.
I’m a fan of the Lucas products and use them on small engines. Thanks for the informative video!
I've used the stabilizer for years, but this was my first time trying the stop leak product.
Before you put lucas in you have to warmed up engine.
It helps more to have warmed up your lucas.
4 to 6k for a 2013 h6 head gasket replacement... 190k miles on the car. So not worth it. Givn this a go
With lucas products. I find it easier to leave the bottle in a jug of hit water to warm it up. Makes it easier to pour
Oem oil filters from subaru are trash. They are identical to fram on the inside. Wix xp is the only way to go.
Subaru is the only vehicle I have gotten since I was 18. This is literally the issue I have been dealing with. Glad to know I’m not the only one.
I’ve had an external leak on my 97 outback. At first I thought it was an over tightened oil filter because when I did the oil change myself it got a lot better, but it’s still there. I’ll try this on the next three oil changes and see hie it goes. I do have 243k milfes though and my pcv valve/the hoses were caked with oil and carbon. Cleaned it and changed the pcv valve and it’s better but still oil is getting through and on the pcv. Maybe this stop leak will help me because I’m definitely not taking this engine apart if anything I’ll buy a new one
Thank you I’ve had the same experience with the product also.
You sound honest. I use a modicum of lucas in 200000+ mile work rigs.a bit heavier oil stops seep leaks. 10% lucas is more than adequate in cold climates. If oil stays on dip stick when cold I find very quiet and quick cold starts. Quiets lifter rattle too!
99% of stop leak or additives are bogus... However I have used Lucas stop leak for a P/S pump on an old f250 diesel and it outright fixed the leak "permanently" had it for years after and never had to top off the fluid again. I was shocked. Currently trying the engine oil stop leak on a 5.7 hemi, 190k mi, fleet maintenance... Very small leak, maybe a drip or two overnight. We'll see!
Did it work on the 5.7
@Sergio Arreguin I put a crate hemi in the truck for like 12k... fatal hemi tick. But before that, it did not work to stop or slow down the rear main leak, used as directed over two oil changes.
Atp 205 is the real deal. Everything else is garbage.
Informative video. I Have an 06 Impreza with a mysterious leak. Will consider doing the same. Has the leak still stopped? Have you had any issues after adding it?
Sometimes warm up room temp and mix in a half quart motor oil. Shake and serve warm to hungary guests! Lol
Chris fix in the making. Great vid man
High praise indeed! Thank you!
if you leave it in the house or out in the sun itll flow a lot better this also helps with diff fluid
Is this still running well?
Do we have to drain oil out before putting this oil in? I got smoke out after putting it in
Can you please tell me what oil you are using in the car now. I have the same exact problem with my legacy as you had. Did you go with a heavier oil like 10w 30?
You might actually be my savior! Is it common to see a very minor coolant leak along with an oil leak if you have a head gasket leak? I am not having a problem with overheating, but because my coolant is leaking a little, I am hesitant to try Lucas right away.
If your head gaskets are leaking coolant, I would definitely change the head gaskets.
You should definitely add it to every oil change. Either that or alternate Lucas stop leak and stabilizer.
There's only two of the snake oil products I use. The Lucas stop leak and the Bars liquid aluminum for head gaskets or cooling systems
I recently got an oil change and the shop I went to used a Napa oil filter. The oil is pooling by the filter and that’s caused a lot of oil to leak in the engine. Could the issue be it’s not a Subaru filter? The filter is not loose
A leak around the filter is most likely an installation failure. The rubber seal around the perimeter of the filter could have been knicked, even a tiny scratch can cause a leak there due to high pressure. You might try tightening the filter, or even better, have it replaced.
And........I don't want to. I hear ya man! I'm no math guy, but 4.5 quarts x .20 is 0.9. Wouldn't that be about 90% of the quart bottle instead a little more than half?
Yeah. 90% of the bottle is a little more than half. Haha.
I put in about 3/4ths of the bottle.
@@Rustbelt_Research Thanks for the clarification! I'd hate to put the wrong amount and kill my car, which is already on death's door. :P
You can also use RCM branded filters for subaru as thats exactly what theyre manufactured fof
I have the same issue? Can I have an update how’s it going now? I have 170k on my forester
I put about 10K miles on this car with no problems after adding the lucas. No more oil smell on the exhaust. Added the lucas with each oil change.
Ended up selling the vehicle earlier this year, still with no perceptible leak.
I'm a fan. I think it's a great product.
@@Rustbelt_Research thank you for this update.Always been a fan of Lucas products and glad to hear this.BTW are you putting this product in each time you change the oil ?
My 06 Impreza is going to get this treatment today!
Well ….. I did it and only had to drive 15 miles before the burning oil smell went away! 🤣🏆 I drove a total of 65 miles and this product is definitely a big plus. It was a small leak from the head gasket on my 06 Subaru Impreza. So small it didn’t leave oil on the floor. Just enough while driving to drip on the exhaust and flow into the cabin when outside air was selected on the hvac control. I will use this every time I change the oil, 🙂
Thanks for this video! I have a 2007 Outback (basic model) with a small leak around the cylinder head block according to my mechanic. Will this product be okay to used? Thanks in advance.
Yeah. If it's an external oil leak it should work exactly like in the video. If it's an internal leak, and the car is overheating, this won't do anything.
@@Rustbelt_Research i have the iverheating issues even with a new radiator i dont know how it happened i didnt even drive it hard
Hi...i got the same problem in a 2007...question di you put the motor oil first
They r def not all snake oil lol. Do u realize how much research goes into some of these products? Its crazzzy how much r$d. Thanks for the video hope all is well!
I have a small oil leak on my 2019 Subaru Wrx just got a oil change about 10 days ago.Should I add the Lucas oil?
Use AT 205 for leaking seals. This for other leaks types
If you have developed a oil leak after having a garage do an oil change and you didn't have the leak before, take it back and tell them they may not have tightened the drain plug or oil filter properly.
It got stop because the fuel bottom was sealed in the hole. A slight lift would have let it flow.
Great video thank u
My 2017 Buick encore is doing the same thing oil on the engine block and they say it's the head gasket I just got oil changed maybe I should try this
Can I use this stuff on a Honda Accord, 98 model
I don't see why not.
You dont seem to comprehend how the oil filter bypass valve works.
It opens due to clogged filter paper.
You are correct that some valves open at 10 psi "restriction" and some 20 psi restriction. That means a partially clogged filter.
No, the oil bypass valve will open simply because the oil pressure is too high. It is common with Subarus.
have you ever try the AT-205 Re-Seal from app automotive ?
absolutely amazing
Great way to clog the heater core in Your Subaru's heater.
What? Did you literally even watch the video?
@@Rustbelt_Research LOL😂😂😂😂😂😂😂
did you do the second review ? what was the outcome ?
I'm working on that video now.
Think I'll give it a try. Got the odd drip from mine, which like you say smells really bad . . .
Why not put a shield above the exhaust instead some drip pan
You think this would apply to a 2016 Outback, I've got a 2.5 with 152000 miles and I need like two quarts for 6000 miles
Can't hurt. Either it will help, or it won't.
is this still working well? I have a 2006 with the exact same issue. thanks
$2k car? Are you kidding me?! Its like $6k where I live 🤷♂️ I'd be doing that the first weekend I have free.
This car had a wide variety of problems other than this leak.
Atp 205.
Hey man question i have the 2009 subaru forester 2.5 liter . So far is only seepage not leaking oil no coolant .hardly lose any oil between oil changes . It has the single layer mls gasket . Can i drive it like that no problems. I heard i can go years with it no problem as long as i monitor oil levels ?
Somewhat confused. MLS means "Multi-Layer-Steel", so you cannot have a single layer MLS gasket.
If you're getting a little external oil seepage, I wouldn't be concerned at all. Just monitor the oil levels and maybe add an additive like this or switch to a thicker oil.
@@Rustbelt_Research so your Subaru the entire time was driven to 190,000 miles with just an external oil head gasket leak ? Never leaked coolant ? Last question thanks 🙏
@@FreshMikeable Yeah, external oil leaks without ever leaking coolant or overheating are very common on later Subarus. The catastrophic overheating type of head gasket failure was mostly only on the late 90's and early 2000's cars.
Really it's not a big deal in terms of drivability, but the design of the engine means the oil leaks directly onto the exhaust manifold and smells really awful which is irritating.
Next time try ATP 205
Worked for my Civics external head gasket leak for a while but it started leaking again.
You have to put it every oil change
Do you think it would work the same on a Toyota Prius? Tnx
Probably.
i have minor leak on my piston liner its very very minor not worth it to bring the engine to complete rebuild will this one work?
Give it a shot. Can't hurt.
I tell most people to never buy a Subaru lol. I suggest buying a Toyota Corolla or Camry or Toyota rav4 if you want all wheel drive
Toyota makes lousy AWD. In any comparison, Subaru's are the absolute best hands down. NOTHING compares to Subaru AWD. Period. Due your research before making stupid comments that make you look ignorant.
@@jameshanna7914 get a truck you seem to be as stupid too cause you answered a stupid statement I look for reliability over a engine rebuild
Just get a Subaru that has the head gaskets done.
Thx
Would it be harmful to try it for a Subaru Forester that may have a gasket leak that may be what is causing a lot of coolant bubbling without it running very long? It passed a block test at the mechanic before we replaced the radiator hose and thermostat.
It won't do any good, this is a fix for a head gasket leaking externally. If the coolant is bubbling the head gasket has failed internally.
Your car needs to have the engine taken apart and the head gaskets replaced. In the mean time, DO NOT DRIVE THE CAR. If it overheats you risk irreparable damage to the engine.
Use a head gasket sealer
@@jonathancoy5542 These products absolutely do not work, any product that claims to seal an internal head gasket leak is basically snake oil as far as I am concerned.
At BEST it won't work, but usually they absolutely destroy the cooling system and sometimes the engine of your vehicle.
@@Rustbelt_Research second that. External leak on the block/head is usually similar to any other oil leak.. oil pleasure of oil pump pushes through the weakest escape. Internal leak of head gasket no longer related to being a basic "oil leak" as the pressure is coming from the combustion itself.
Hi , great video , how is the engine going now
I don't have the car anymore, but it continued to run great until I sold it.
@@Rustbelt_Research thanks Mate
Might as well put in 20w50 for thick oil. For beater cars
I would be very hesitant to add oil that thick to a vehicle engine where I live, it gets so cold outside you'd risk the oil jelling.
@@Rustbelt_Research but adding this goop stuff is fine?
@@1marcelfilms Yes. Because of the ratio of the product to the oil, it's not going to increase the viscosity that much. This car takes 10w30 oil from factory. Once I added the lucas product, the oil is probably more like a 15w30. Which should not be a significant enough change to cause damage to the engine.
There is relatively little of this product actually in the oil.
@@Rustbelt_Research interesting
@@Rustbelt_Research I'm gonna guess you live in the northeast US. Pennsylvania? I live in New Mexico now and your roadtrip video made me homesick.
Very interesting video, thank you!
It depends on how worn out the engine seals are .. the more worn the less it will work. What it does as swell the seals alittle.
AFAIK this product does not swell seals. It literally works primarily by making the oil thicker.
@@Rustbelt_Research I've never used that brand .
@@Rustbelt_Research take radiator cap off .back the car up and drive a newer model under cap and tighten . Done 😆
@@kimdecell5096 I drove this car for quite awhile after this repair. Then I sold it to someone else who continued to drive it. It was a good car for me.
Barrs seal helper I used or honey oil . STP. use to throw a bottle in any use car id buy for the hell of it they don't work miracles lol.
Do you think I can use this product to stop some oil leaks from the serpentine tensioner gasket? My car is a 2006 Toyota Corolla LE. The repairs can cause me between $700.00 and $1000. Recently, I just changed my horn because it was not working anymore.
Thank you!
Worth a try. Worked great for me.
These type of products are ok on worn engines if used carefully...otherwise it can clog the oil galleries resulting in loss of oil pressure.
I do not think the Lucas product will do that, as it doesn't contain the "Aerobic Solvents" (Sealant which reacts to air) other products like "Barrs Leaks" do.
I'm not 100% sure how Lucas works, but I think a huge part of it is just making the oil thicker, in which case the oil stabilizer might work nearly as well.
I have a 2003 Dodge Ram 1500 4.7. I run full synthetic in it I’ve got 150,000 miles as of today. I got the valve covers changed and it’s still losing oil not sure if it’s a leak or if the truck is just using it. Should I use Lucas engine stop leak while running full synthetic? Or just leave it alone? Also no leaks on the ground.
You need a thicker oil. Maybe 10w30 vs 5w30. My dodge has 182000 on it and I noticed it was using oil after long road trips. Added lucas oil stop leak and hasn't used oil since.
RESTORE.
mechanic in a can. It works.
The Japanese pronounce as SU- BAH -RU.
sawdust works as well unless Lucas gave you the stop leak for free...
yeah... more than likely its a valve cover gasket that is going out and is dripping on the exhaust manifold. that creates the smoke inside and out. If it was a head gasket.. it wouldn't be oil. it would water or radiator fluid. that creates a sweeter smell. but based on this review...thats good to hear. It give people some light since a lot of people change valve cover gaskets and not 100% fixes leaks esp if you buy aftermarket. this solution def helps doing the work again. ...KEEP US UPDATED! ty
It's 100% the head gasket. On these later EJ25's the head gasket leaks oil externally, which drips on the muffler. The valve cover gaskets on this car are totally dry.
As far as an update: 5K miles later and still no leaks. I'm pretty pleased for the price.
