My 92' Silverado 117k original miles runs cooler after adding pro-lube. To me, that proves smoother interaction of oiled surfaces within the engine. It also significantly reduced the"hemi-tick issue on my 2018 RAM. It's in everything I run now.

I have an Exterior Cleaning Company and first used Prolube in one of my Service Trucks . I couldn’t tell a significant difference at start up with just the recommended amount of Prolube but within the first couple of days I did notice the motor running smoother and over the next couple of days a significant improvement of engine performance and slightly better fuel efficiency. Over the next couple of weeks I now have it in Every Piece of Equipment I Own Pressure Washers , Two Service Trucks, Tractor and Scagg Zero Turn Mower . Great Product. You Won’t Be Disappointed. I am fixing to order another gallon 👍

As most of you, Toyota Tacoma owners know, the V6 engine tick loudly. I purchased the pro lube in hopes of quieting the tick down which, it did do. Although it-didn’t completely go away, it is better than it was not to mention the hidden benefits this product should give me, this is my first time using Pro Lube so far, I have no complaints.
