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."

    High mileage vehicles

    I have several high mileage vehicles of all kinds. It’s nice having the peace of mind feeling they are better protected. From doing my own personal research I can’t disprove any of their claims or advertising. I definitely feel comfortable with their product and I recommend it to my friends. I’m even adding it to my jet car.

    Took the baby rattle out of my 19874mi VW diesel

    My first experience with Prolube was at work. We have an industrial gearbox on a large electric motor. The gear box drives a cutter for beveling the ends of large steel pipe. It drives on two 3 speed straight cut gear sets. One set was shifted while stopped and the motor turning. The teeth were sheared smooth off two pair of gears and deposited in the bottom of the transmission. After removing the debris and oil from the transmission, we ran the system by hand in the remaining gear pair. It was a bit grumbly but serviceable. We refilled the transmission with oil and operated. Still grumbled but not louder under load than unloaded. Next we added Prolube and the whine of the secondary gears as well as the grumbling reduced to quiet gear whirring.

    At my usual oil change interval with my ‘04 TDI I added Prolube with the new oil and filter. I have run VW 4 cylinder diesels since 1980. All of them have a specific rattle, especially with the engine vanity cover and hood blanket removed. After starting my bug in my metal barn, the idle rattle disappeared within seconds of startup. I normally get a longer than normal startup noise after oil and filter change. Not this day!!! Subsequent cold starts were as quiet as rapid run, kill, and restart sequences. I have a very efficient coolant thermostat, my coolant still runs at the same temperature as before, but takes miles more to reach regulated temperature.

    I have also added Prolube to my other vehicles with positive results. My…

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.
