Slick-50 61399750 Engine Treatment 750ml & 60199080 Manual Gearbox Treatment, 80 ml

Really helps with older engines. Supports with minor oil burning.

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.

I have used STP Additive for many years satisfied with the result knowing that it is protecting my engines.

I use this in every oil change it's fantastic lasts 40 thousand kilometres and more milage highly recommend

Thanks

Always hard to know if additives are needed, but good insurance for higher mileage engines

What can I say this product is fantastic it has reduced the temperature (running) in my BMW and reduced engine noise. I have found it runns better and excellent performance in my opinion. All reddy got my next bottle reddy for its service in 11 months time.

Used it for years and so far always been happy with it
