Tried Prolube treatment in my work truck. 160k plus. Noticed in about 10 minutes that engine sounds were quieter and I swear less vibration. Next day in the way to work my check engine light went away. I was amazed. Needless to say as soon as was home we treated my wife’s Mercedes. Next test is trying this out on our commercial trucks. Stay tuned.

I wanted to see if it lived up to the tick-tok videos I had been seeing. An boy I was not disappointed! Used the product in my diesel engine of my 2500 high country immediately noticed the difference in the sound of the engine. I also put 3 oz’s of the product in the transmission an it really did seem to shift smother. I’m a believer an will be using the product from here forward. Thanks prolube!

After watching your videos on Facebook and YouTube I decided to order some for my truck. I used Royal Purple Delvac super 15w40 and your Prolube and I could tell running and shut down is smoother and I can’t wait to see what the oil is like after 10-15k miles. I love the product so far and would love to see a test video with your machine of my oil since I don’t think you’ve done RP 15w40 as a test
