ALEX J. - North Carolina, USA

GREAT PRODUCT A+

"I used a vibration sensor that’s 4-20ma, 4=0 inch per second and 20ma = 1 inch per second movement. After adding Prolube the engine vibration did decrease some. Went from 7.000ma to 6.833ma after adding Prolube."

    Many uses!

    I was researching this stuff for a long time, then finally bought a gallon. I used 8 ozs on an oil change in my 2918 Yukon with a L86 (6.2) motor, with 143,000 miles. The engine is smoother and quieter. I also used in my 2024 Chevy 2500 with the L8T motor(6.6) with 20,000 miles, it a quieter motor. Also used it in my gear box on an old 60” shredder, it’s a lot quiter. Not to mention I put 2ozs of prolube after a break in on a new hydrostatic transmission yanamar tractor, it sounds amazingly quiet, this additive is very good brand, very good investment.

    The best

    Jeep owners know what the engine start knock is all about!

    By adding Prolube to my 3.8 engine, my engine knock is gone at start up. I started my engine before adding Prolube and while it was running I added the correct amount and you could hear the normal engine sounds get quieter as Prolube was being circulated. Thanks for a great product!

Got Questions? We Have Answers!

What can I expect on my 1st oil change with Prolube Oil Treatment?

After your first oil change you can expect your oil to be darker and the following oil changes will stay cleaner longer with each use as it removes deposits. While every engine is different, most engines will experience smoother & quieter operation.

How often should I use Prolube Oil Treatment?

To maintain the products benefits we recommend adding Prolube to every oil change.

How much Prolube do I add to my oil?

Treatment Ratio:

  • Engine (1 oz of Prolube / 1 quart motor oil) For best results, use 2 oz of Prolube / 1 quart motor oil
  • Differentials (2 oz of Prolube to 1 quart of gear oil)
  • Transfer Case (2 oz of Prolube / 1 quart of oil)
  • Power Steering Pump (1-2 oz of Prolube / 1 quart of oil)
  • Automatic Transmission: 2 oz MAX of Prolube Oil Treatment
  • Manual Transmission: 1 oz of Prolube / 1 quart of transmission fluid
Do I need to drain some oil out before adding Prolube Oil Treatment?

When adding Prolube Oil Treatment to used oil, make sure there is room by draining some oil out beforehand. Make sure not to add Prolube Oil Treatment to an already full crankcase, doing so will exceed your engines maximum oil capacity and can cause engine damage. If your dipstick shows that the oil is below the maximum mark, you can usually add Prolube without draining oil out.

Is Prolube Oil Treatment compatible with regular and synthetic oil?

Yes, Prolube is suitable for use in both synthetic and conventional engine oil.

Is it OK to use Prolube Oil Treatment in motorcycles with wet clutches?

Yes, use 1 oz of Prolube per quart of engine oil in motorcycles with wet clutches. Check the owner's manual beforehand to ensure it does not specify against the use of friction modifiers.

  • Metal-to-fiber wet clutches is OK ✅
  • Metal-to-metal wet clutches is NOT OK ❌
Will Prolube Oil Treatment void my warranty?

No. The Magnuson-Moss Warranty Act allows consumers to use additives of their choice without voiding their warranty except for specific additives that have been noted as incompatible. Vehicle manufacturers are not allowed to void the vehicle warranty just because aftermarket parts or additives are on or in a vehicle.

Should my motor be broken-in prior to using Prolube?

Yes, new engines need friction. We recommend following your engine manufacturer's break-in period before adding Prolube Oil Treatment.
