PROLUBE I’LL PUT THAT SH*T IN EVERYTHING!!!

"Boy was I blown away, this is the catsmeow. My truck feels completely different. I could tell the difference as soon as I hit the road I have smother shifts. I’ll be a lifetime return customer."

JUSTIN M. - South Carolina, USA

GREAT STUFF

"Tried just about everything on the market, after putting this in an engine and listening to a lifter tick disappear it shocked me. Honestly have never listened a tick just go away and stay away. Great stuff. Will be ordering lots in the future."

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."

    With promising sliptivity...

    I bought enough "rattlesnake oil" in my lifetime..

    However watching your ad has once again brought some confidence in my purchasing game.

    I've added Prolube to my wet clutched 84 Goldwing..

    Had a slight tick ..now after 5 ozs of Prolube it's all but gone. "I'm still checking results..I only have 1 drive on it in 2 days .

    Also added 5 ozs. to my 2017 Nissan Frontier 2.5 l

    With 107,000 I hoping for a long life.. at least for my truck..lol. Yes the proofs in the pudding...

    I've been a long time advocate of Marvel Mystery oil ..

    With positive results from that also.

    I'll update my review as the miles climb.

    Thanx to all involved.

    Best anti friction additive ever.

    I have a 2007 Chevy 2500HD truck with a 6.0 gas engine with 300,000 miles. It has had a tick at start up until warmed up since 100K miles. I added 4 oz. Prolube and the tick is gone. Amazing product! I am using it currently in 4 vehicles with high mileage.

    Too good, (to be) but true?

    I purchased prolube as a tested for my two vehicles. 19 subaru wrx sti and a 17 nissan titan pro4x.

    Both of these vehicles have particularly sensitive engines but with TLC can run a very long time. I used Prolube on my oil change and noticed a significant reduction in vibration, noise and the oil came out looking great.

    I was sold after doing the water bottle test on the engine and saw nearly no movement in the water after prolube was used and engine ran for 10 minutes and went from heavy vibration to steady water. Curious how longevity will be. Also noticed in my Titan the injector tick is much softer.

    I also pulled a trailer with the titan (10,000 lbs) 1900 miles from the south to northwest and the truck did a lot of grades along the way with zero issues. Going to do an oil test on this change at 4k miles. I have very high hopes that we will see drastic improvements.

    The videos I supply are the truck running 15 minutes after oil change (Penzoil platinum synthetic 5-30) by itself waterbottle vibration test.

    The other video is 10 minutes after adding prolube (about 5 ounces) and doing the same water bottle test. You can see the reduction in vibration and audibly hear the difference. P.s. I ensured the vehicle was at idle, operating temp before performing test. Solid proof for sure.

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.
