10002 Heavy Duty Oil Stabilizer - 1 Gallon | Premium Engine Lubricant Additive Friction Reducer Performance Booster Automotive Vehicle Maintenance Multi-Functional 3.78L

I’ve got an old dump truck with quite a bit of blowby. This stuff works great at reducing that and coating the cylinders and extending the life of the engine. But if you’re in a colder climate, I recommend putting this stuff somewhere warm before you go to use it. If not, it’ll take forever to pour!

When it's cold this stuff doesn't flow very well to get it into the fill hole in a funnel, and it's stringy when you want to stop, have to use the cap to cut the oil "strings" when you pull it away from the funnel, and if you touch it, it's like a gooey mess to clean off. If you are adding it to an engine, it's going to take a while to get down to the oil pan to register the proper level, so it's best to measure out your total volume needed and dump that in, then at least you know your engine has the proper oil volume. That's my only complaint, otherwise, this stuff is amazing. I fist tried it many years ago in my Toyota Tundra, which was already a very smooth running truck, but this stuff seemed to take it to another level. Very quiet, very smooth. I have since began to put it in everything, my lawnmowers, my riding mower, motorcycle, differentials in my Ford F250, wife's car, basically anywhere it says it can be used, which is a tremendous number of places, I have used it and I have seen dramatic improvements in noise reduction. My riding mower seemed to have the best results. Very noisy V-Twin engine quieted down to almost no noise compared to running without this. I assume all of this is due to no more dry starts, and this stuff clings to whatever is supposed to be lubricated by the oil more than just plain oil does. My motorcycle really shifts nice, runs very quiet now. Not only noise reduction, but everything seems to shift better, change gears easier (rototiller), just everything that I have used it in seems to benefit. My tractor and truck diesel engines just seem to run so much smoother and quieter. Can't say enough good about this product. This is the first additive of any kind that have used that I would say does everything is says it will do without any reservations. Now I always keep some on hand to have for any oil changes, normal maintenance. I always shop around for the best price, which can change from time to time, but you won't be disappointed with this product. The range to use in some applications is 25% to 50%, which seems like a lot, but don't be afraid to just follow the directions.

I use this in old wore out stuff. It helps. I’m not sure I’d use it in non wore out stuff. But it does slow leaks and oil consumption.

Stuff is awesome, super thick and slippery.

Great product!

I use this in all my vehicles for my 2015 Subaru Forrester, my RAV4’s, Honda Ridgeline, and even my Prius prime. It makes the engine more quiet, run, smoother, and more efficient and has better wear protection. Because of this, my Subaru Forester no longer burns oil

Great deal

I've heard lots about the Lucus products, both good and bad. One warning about this product is it's THICKKK, almost like pouring out a bottle of honey/snot. So you have to go slow or it'll be messy, you have to wait for the little trail to finish. I tested this on my 2014 GMC Sierra, slowly adding half a quart instead of a whole. It was something I decided on my own, but I had the engine warm and running, I wanted to mix it into the oil as quick as possible. Being as thick as it is, I was worried pouring a big blob of it in then starting the engine would clog stuff. The results surprised me, the engine ran quieter and smoother. It wasn't a huge difference, but enough to notice. Starting it up after a night of sitting was much quieter too, it sounded like it was just easier to spin over. Then I tried this on my girlfriend's 2017 Jeep Renegade, doing the same routine except I poured a bit in then started the engine and then off, repeat until I got about half a quart in the crankcase. The same results happened. It ran quieter, quicker to start, and there was nearly zero rattle noise while driving. And I don't know how, but the throttle felt quicker. It was the most annoying part of driving that car, it always felt like a slug. It wasn't amazingly fast, but it felt more like how a little car should accelerate. Overall, it is a awesome product! And if I could extend the life of my vehicles using it, buying a big bottle every couple years is still way cheaper than buying a new car!

Make my car run smoother

Perfekt zu empfehlen

Lo compré como aditivo para mi Ford Expedition y me funciono de maravilla

Great product. I use it as assembly lube. I add to differentials. I add a bit at oil changes. Although not scientific, I put a drop on a steel plate, then placed a large washer over the drop, then started rubbing the washer against the steel plate, then applied a heat gun to all this while I rubbed the washer against the plate, my gloves basically burned and I never encountered any friction and it beat out greases and oils I normally use under same test conditions.

Arrived next day, as expected. Pricing is better than Canadian Tire and local parts stores, this is a great product and works very well.
