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."

    Better Gas Mileage - Fact

    Just changed the oil at 200k and ready for a 4 hour trip. 1st fueling I got 14.1 mpg in my stock 2006 Nissan Titan. After the return trip and additional town driving since I have 1/4 tank of fuel. After refilling, my milage tally was 17.3 mpg. Normally, I get around 13 mpg on the city/highway.

    Prolube is truly the Best.. for Kia/Hyundai engines Verified Purchase!!

    First I am not a paid sponsor...just a super commuter. I had at least 3 Kia souls over the years .my current 2016 Kia Soul I am well over 200k miles on the 1.6 4-cylinder. This is unheard of ..even the dealer was wondering what is keeping my Kia soul alive...Its PROLUBE!!! I commute from long island to Brooklyn, NY every day for work. How my Kia souls last is Thanks to Prolube and changing all fluids annually!! Prolube protects engines from heat and burning oil and it increases the protection or break down of burning oil. It can be 90s to 100 plus degrees outside and never runs hot and still gets me 33 miles per gallon at high 65plus mph( for legal reasons😃). I have used every additive that claims to protect your oil, Lucas, stp, est (any down the Walmart Isle....all costing $20 plus dollars and no change in performance. Prolube as stated the proof is in the pudding!!! Prolube should do a trip around the country and let People see the difference!!!

    AWESOME

    Added ProLube to all three holes in my 2015 Harley-Davidson FLHTK ULTRA limited with 40,000 miles. Runs smoother, shifts better and primary is quieter.

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.
