I ordered the prolube for my 1991 Mustang GT and for my 1979 Corvette I notice a difference in both vehicles, after adding with a new oil change. Both cars ran smoother and quieter.

Product seems to be doing what it's intended to do. My truck seems to be running smoother. I have added it on 2 oil changes so far.

I run 1 quart/10 gallons of motor oil in my 95 Pete with a 3406e motor. Motor uses 1/2 gallon less oil In a 10,000 mile operating distance. And oil samples come back with better viscosity at 100 degrees Celsius. Would recommend this to anyone with a semi truck.

I'm not a snake oil easy sell, I don't buy mechanic in a bottle stuff. I really went out on a limb with this, and got better than expected results. I immediately noticed a cooler engine temperature and increased oil PSI!! By 4 degrees and 8 psi, which is very noticeable with the L98..Prolube did indeed improve operating conditions...absolutely amazing. So paw paw ain't telling no lies.."Proofs in the pudding!!" I will definitely be purchasing again!!

It's not snake oil! I added it to my 2015 Harley Davidson Street Glide Special with a 103. Around 2 min after not warmed up I noticed a significant reduction in vibration in the bars and mirrors at idle. After a 1 hr ride the head temps were around 12-16 degrees cooler than normal. Added it to the transmission and it shifts smoother and quieter. I'm extremely shocked and will be a prolube customer for life.

Running prolube in a Detroit diesel series 60: I was very curious how this product would work because I’ve used others that did very well .. But Prolube made my 1.2 million miles Detroit idle so smooth and quiet and I didn’t even have enough for the full treatment i needed 44 oz and only got a quart and it still did awesome ! Can’t wait to get a gallon!!!!

My Corvette loves it and I Love it! I'm 65 years old I've used lots of additives and this one really works. Can't wait to get it in my other cars and my diesel truck.

Got Questions? We Have Answers!

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
  • Heavy Duty/High-Mileage (3 oz / 1 quart motor oil)
  • Differentials (1 oz of Prolube to 1 quart of gear oil)
  • Gearbox (1 oz of Prolube / 1 quart of oil)
  • Power Steering Pump (1 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.

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, we recommend following your engine manufacturer's break-in period before adding Prolube Oil Treatment.
