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."

    Great product!!

    I don't normally write reviews for products, but I really felt I had to in this case firstly, I'm in Canada so with the exchange rate the shipping and the duty this cost me close to 100 bucks for 32 ounces even with the high cost, I have to say the product is totally worth it. I'm an outside sales rep and drive a lot for work like 3 to 4 hours a day. I put this in my Lexus and immediately the first thing I noticed was how much smoother and quieter the car was it actually felt like a Tesla at a stoplight. You couldn't tell the car was even running. It was a little peculiar to be honest, but the next thing I noticed was besides how much smoother was starting to get some mile per gallon numbers that I haven't seen before, so I put this in every vehicle that we have they're all running smoother they're all idling lower. They're all using less fuel and it's nice to know that I have an extra layer of protection. I would highly recommend this product to anybody as it even got rid of the valve tick on my Sc430 which has 190,000 miles . I decided to give it a try and now I'm a believer Pro lube for the win!!

    First time use

    I didn't know what to expect honestly . You read so many things about additives but i can say this product has taken away the small engine noise on my 2017 Outback 2.5. I put some miles on a vehicle for sure and will be putting this in the rotation every oil change now. The proof i needed was when i poured using the measuring cup it took me forever to get the cup clean of product…. I used brake cleaner even and it tries to stay even. To me it stays lubricating no matter how thin the oil becomes it will be on the sensitive parts to reduce wear. I just wish i had more at this point. Thanks Pro Lube

    Prolube!!!

    Noticed an almost immediate difference in the motor after this oil change which included the Prolube Oil Treatment. The motor seems smoother and quieter, can’t wait to see how it improves horsepower and MPG as I continue to use it! I’ll be purchasing more for sure!

    Old Chevy runs like a Cadillac

    Just did my oil change with Prolube, and boy my motor runs considerably quieter and smoother than a golfin dolphin. After putting Prolube in my small engines and now my 350 small block, I'm a firm believer the proof is in the puddin.

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.

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-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 Prolubee?

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