Quality engine product

I know people have their suspicions about this product so before I used it I borrowed a decibel counter and placed it near my diesel engine (65,000 miles) for a before and after count. I drained 500ml of oil and topped up with the 500ml product just in case a full oil change made a difference itself on the sound level. The result is a definite drop in sound by 7-8db so thats very good indeed BUT whether or not the product makes a difference to the inside metal workings of my engine I'm not sure, I'd like to think at this stage the product will do as claimed and reduce wear etc. Fingers crossed.

Used Slick 50 for years very pleased with it. Good price, it arrived on time and it's good for my car.

Bought as it was cheaper here. Good stuff and used it for years

I was introduced to the wonders of Slick 50, by my mechanic friend, which ironically was near enough 50 years ago! I have used it in every car I’ve owned since. My friend described how the engine revs on his Range Rover had increased by a couple of hundred RPM following the addition of Slick 50 to his engine oil. He went on to describe how they had thought they’d test exactly how effective the product was at protecting the moving parts of an engine against wear. They had added some Slick 50 to the engine oil of a car they were about to scrap (failed it’s MOT due to corrosion). They ran it around their yard for ten minutes then put the car on a ramp, left the engine running, then sent it up in the air so as to gain access to the sump plug. They then drained the engine oil. Expecting the engine to self destruct by seizing up after a few minutes, they went about their other tasks in the workshop. My friend left the workshop to perform a test drive of another vehicle, leaving his partner in charge. 20 mins later when he returned he was flabbergasted to find the car still on the ramp, still ticking over! In disbelief he instructed his partner to lower the car, get in it and rev the engine until it detonated. The long and short of it was that they ended up having to give up waiting to witness the engines demise, when the scrap lorry arrived to collect the car, STILL running, hours after all of its engine oil had been drained out of it. OBVIOUSLY Please DON NOT try this on your own car, but I think it demonstrated how awesome Slick 50 really is. Why wouldn’t you put it in your car’s engine. And what’s really fantastic is that you don’t need to put it in at every oil change. One application last 250,000 miles apparently.

Great stuff which actually works and makes a difference; we'll worth the money.
