Prolube Oil Treatment - Engine Oil Additive for Gas & Diesel Engines - Reduces Wear, Noise, Vibration - Boosts Fuel Economy & Horsepower - Works on Transmissions & Differentials (16oz)

I have a 2000 Jeep Cherokee XJ with 392,000 miles. Prior to Pro-Lube she always made her little noises while warming up, then after 5 minutes always quieted down to some degree. After Pro-Lube administration while the engine was running and warm she quieted down considerably more... This morning today with a cold start she quieted down after 1 minute instead of 5 minutes. There is some magic in this stuff..Obviously this product does do what it claims. I will monitor for future/further developments.

Best oil additive I have ever used put this additive in my son’s truck it has a 4.8 ls it had a valve that was making a loud taping noise change his oil and added prolube and no more taping I was very pleased and surprised I had bought a qt just to try it but now I will purchase a gallon best stuff on the market hands down

Item is wonderful it works like advertise how ever the can was smashed to the point where the can would not stand straight up i had to smash and bend back to somewhat normal roundness , honestly I would have returned it but I dont want to wait to receive product for what ever days it would take to get back to me ,I am surprised it did not bust open and did not start leaking all over ,I love amazon and this product is amazing but package dont give any protection!

Have a 2016 F150 with the 5.0 Coyote. They’re known for the lifter tick. Always had it and I’ve tried multiple additives but this one worked and quick! So smooth and quiet now. Good stuff

After watching all of the friction videos by Prolube I decided to try it. I put it in two of my trucks haven’t driven them enough since to give an honest review.

Worth saving your engine. I have 311K on my F150 and this is a great addition to ensure I keep it running for another 300k.

Easy to use, had a fresh oil change and put the recommended amount of prolube into the engine, have a 1999 Chevy Tahoe with 359000 miles and had a knock on first start up in the morning, started it up the next morning and the knock is gone. Works great for me

Bought 16oz can. Only had 14oz in it... have an 8oz measuring cup, put 8oz in one vehicle. And then went to put the other 8oz in another vehicle, and only got 6oz last I checked. 8+6 didn't equal 16.... I don't care how well the product works. I won't buy it again if they are ripping off customers...
