I’ve always added some kind of oil treatment to my Hummer during oil changes. Now that she is getting up there in miles, I wanted to step it up a bit to offer the engine as much protection as possible. Before my oil change was due, I ordered a can of pro lube. I added 12 ounces to the engine when I changes the oil. Upon starting I instantly noticed that the engine ran quieter and smoother. I was impressed needless to say! Fuel mileage has gone up slightly as well. Just an over all smoother operating motor. With the left over pro lube I had, I added that to my lawn mower too. I definitely would recommend Pro Lube to anyone on the fence about trying it. The product works and my 2006 Hummer H3 with 160,000 miles on it is proof. I know I will definitely be adding Pro Lube to all my motorized vehicles! Thanks Guys! Great product!

I’m running it in literally everything. My tractor is more quiet. After dropping a turbo awhile back, I feel much better having it in my truck. I put it in the hydraulic fluid in my zero turn mower and it fixed the whine. I’m going to start running it in my lower units on boat engines as well.

I have small construction company and my 2006 Dodge 2500 with the 5.9 Cummins is in shop getting a motor rebuild. And at the same time my engine in my 2018 silverado is eating itself. So I ordered prolube and the video speaks for itself. If this helps my truck continue to run until my Dodge is up and running again im going to change this review to 5 stars!
