Prolube Oil Treatment - Engine Oil Additive for Gas Diesel Engines - Reduces Wear Noise Vibration - Boosts

Ok, I’ve been a car guy my entire life, working on my own cars keeping them running. I used this stuff on my 2003 trailblazer with the 4.2 inline 6. It has 192k miles on it. And cold start it had a loud lifter tap and a little bit of piston slap as well until it warmed up. The lifter tap stayed (quieter) but was still there with the engine warm. Yesterday morning I changed the oil again. Did the double dose (used the 16oz can). And first start after oil change the cold start tap was 90% gone. Drove it last night and when I got home it was completely quiet at idle warm. This stuff absolutely quieted 90% of the cold start lifter noise, and completely 100% quieted down warm lifter tick. It works amazing and I’ve always been skeptical. Especially something I found on instagram reels. But try it. It really does help a lot, it is expensive but I’ll keep using it with the results. To add, it may be a placebo affect from the lifter tick going away. But throttle response seems improved, and it seems to have gained some power. Not a ton, but noticeable enough to make you happy after your first drive trying this stuff. Read more

10 stars this is the real deal. I put 3 oz in my transmission as directed on instructions and it immediately stopped the shudder that occurred even after a tune. Also I put it in my engine oil and the engine definitely has a smoother feel with significantly less noise. This product is far better than anything related ie (lucas oil) officially have been converted to a believer. Value for money is bar none buy some now, especially if you drive a Silverado with afm and a 6l80/90 transmission this stuff is gold!! Read more

I have a 2024 Mustang GT Performance and imminently got 4mpg increase and the engine was A LOT quieter at idle and deceleration. It was also a lot smoother. This stuff really works, I'm not used to that. Usually stuff like this is snake oil. Read more

Awesome product. Used it with a new oil change in my car. My car is only a 4 cylinder and sounds like its going to die going uphill but after using and adding some of this. The loud sound uphill is gone like its not having a hard time uphill. Seems like it added more power too. Read more

Pro lube lowered my idle on my 04 f350 v10 no codes. The truck runs excellent but runs a little rich. The idle allways staying at 1000, I put in less then recommended and it stayed the same, after a couple of days I noticed a tic so I put in the rest of the guart and the magic happened. 3/4 of the quart went into my v10 The tics stopped and an idle lowered. This is now what a well oiled machine sounds like. Read more

Great product, works well with older vehicles Read more

This stopped a sticky lifter from making any noise in my 88’ Silverado. I also added it to my 2019 Ford 5.0. The valve train was a little noisy to me. It quietened it right down. Read more

This stuff is amazing... Add to oil and trans... My uncle had a Chevy Tahoe 500k+ on it. Always mobile 1, wix filter. It developed a slight knock/tick after that, which would stop after it warmed up.Found this stuff. Added a bit, and it immediately subsided/didn't return. I started running it in my ford Windstar 2001. She purrs like a kitten and shifts like butter after I get er warmed up now. 180k+mi Read more
