Lucas Oil10001 Heavy Duty Oil Stabilizer - 1 Quart

Good Price for the Large Size and Works Well as usual

GREAT PRODUCT-

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!

I purchased this heavy duty Oil stabilizer specifically because of excessive knocking. Especially, when I start up my truck. Watched a YouTube how to video, and a fella mentioned he had a similar issue. Low and behold he used the stabilizer, time lapsed video. No knocking.I poured this in after fresh oil change. Drove my truck for a couple of days and success! Knocking is gone, and on start up and no knocking. Yesssss! The performance of the engine was very surprising. Truck drove great and just freaking smooth! Gonna test the gas milage and see if there's any improvement. Also, this fluid is super thick, and sticky if it gets on your skin. I literally got a drop on my and hand, it was hard to get off.But overall this absolutely did the job!

I have a Turbo Audi. Ever since I bought my car I always needed to refill my oil in between oil changes. Now that I know about Lucas I mix it with the car oil and it makes a huge difference! It saves me on oil and I get a little bit more mileage per gallon of fuel. Great product!

I like this product; I've used it for a year in my old Honda and a couple of months in my newer Honda. As for the claimsReduces oil Consumption, deffinate Yes!Elimates dry starts? Yes!Raises oil pressure? Yes!Increases oil life and engine life? Unsure, If there is a increase it's mostly negligible, perhaps it depends on the oil weightEngine life increase? Yet to be evaluated but I do believe it may do this. This is because the composition of the oil gains more of a tacky like ability and doesn't change the viscosity of your oil which allows for better "coating" protection of the cylinders and piston rings.Overall, my car runs much smoother since using it, and although Lucas claims 20% Stabilizer, 80% Oil, I do more like 5% - 10% Stabilizer and the rest oil.I'd caution anyone about using oil additives but with this one, that is not the case.

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’ve been using Lucas Heavy Duty Oil Stabilizer for years, and it’s hands-down the best oil additive I’ve ever tried.
