Prolube Oil Treatment

A family member that uses Prolube religiously offered for me to try some from the can he bought. We measured out the 7 ounces and added it based on one ounce per quart. (6.4L Hemi) Within the first minute I could hear a difference in the noise level at idle. My engine has roughly 150K on it and runs well on a normal day but with it added the truck sounds almost as quiet as most other vehicles now. Engine oil temps usually run in line with my coolant or 10-15 degrees hotter depending on load / terrain. One of the first things I noticed the next day was during a drive from Louisville, KY to Cincinnati, OH for work. With no trailer, the engine oil temp now lived lower than the coolant temp or matching the temp just before the thermostat opens. Towing our 38' travel trailer I was able to get the oil temp to see roughly 10 degrees above the coolant again climbing hills but as soon as the downhill started, temps fell quickly again. I haven't ran it long enough to truly compare fuel economy differences, but I can definitely hear and see the difference in the engine performance. My next test will be adding it to the front and rear differentials. Photo shown is of oil temps with Prolube added. Trans temp is low due to having a thermal bypass installed. If you are familiar with the 66/68 RFE you already know why. Looking forward to many more miles from the engine now.

All of my gas and diesel engines have pro lube Honda civic 218k Kia Sportage 141k ***** rod and massey tractor all engines are the quietest they’ve been since brand new. thx guys O-H-I-O born and proud. P.S. please don’t sell out some big corp will just raise the price and make it cheaper so that it doesn’t work anymore

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.
