I use to use “MotorKote”. Now I use Prolube and have noticed a difference in the amount of noise the engine makes. People are surprised that it’s a diesel engine. They say “ it’s really quiet for a diesel engine”.” (Nissan Titan XD w/150k) Also, fuel mileage is a little better.

I started putting it in all my toys. Cars, trucks, jeep, dirt bikes, atvs, street bikes, boat, tractor, rv, seadoos and small engines. My jeep has almost 300k on original engine and still runs like a top thanks to Prolube.

I recommend you try it. You won’t be disappointed.

Add about 2oz per quart on an oil change for my 3.8L GDI engine in my 2016 Hyundai Genesis Coupe. I like to think it helps. Engine noise is much less than when it was new-to-me a little over a year ago. Not sure if it helps mileage, but I always get around 26-27mpg. We'll see how this engine goes. I got 412k miles out of my 2010 Kia Soul 2.0L. I bought with 38k, now at 53k. Hoping to get at least 200k... I'll try to keep you updated! Bought the gallon this time... Little shipping damage, but didn't leak.

My 1997 Explorer X has 182,000+ original miles, bought in August of 1996! V8 with performance upgrades (SCT tune, Flowmaster exhaust, etc.). Engine runs smoother and throttle response definitely got better. Was already pretty quick, but seems to be a bit faster with Prolube in the crankcase. I put in 10oz as instructed for higher mileage engines.

Morning starts were heart breaking listening to the valve train clatter for 20 seconds before the oil worked its' way up to heads.

I added 6 oz. of Prolube 2 weeks ago and now I smile with satisfaction that my "retirement" ride will outlive me...

You have a new happy customer and sincerely stand by my 5 star rating.
