After 40 years of use, i have nothing but positive experience with this product.
Used this product for over 40 years on a wide variety of engines from horticultural, agricultural and pre- owned cars and motorcycles, this is a quality product which has served me well over the decades and would recommend it as an essential process in the care of any pre-owned engine and as part of the servicing routine of any heavily used engine ie horticultural ride-on mowers and hard landscaping equipment using an internal combustion engine with a 40 hour servicing regime/oil change.Read full review

Never done my cars any harm
Used this in car engines for years, never seemed to have done any harm but seems to make the engine quieter, not sure about using this in wet belt engines I have only used it in chain driven or normal timing belt units, would be good if the manufacturer could shed some light on wet belt engines as lots of cars seem to use them now.Read full review

Good product
I have used this product in all of my cars going back more years than I care to remember. There are definitely good results when using Molyslip, quite a few of my cars in the past have been high mileage and using this has improved performance and wear damage.
It needs to be marketed in more garages and stores, the only place I have managed to find it in recent years is on ebay.Read full review

Molyslip does it for me!
I have used Molyslip for years in my cars, now whether it does make the engines rune smoother I can not say 100% but I can say it does not make them worse that is for sure.
I have used it in engines dating from 1973 through to a 2002 1.8 Turbo Audi engine with no apparent detriment.
That is all I can say.Read full review

Best thing I have ever bought
Ran this in all of my engines for 50 years. Marvellous effect on engine performance and quietness. Gives more MPG and lower startup wear when cold. Stops engine seizures and piston ring breakages and wear. Camshafts last for ever. Fantastic in gearboxes.Read full review

Best engine investment you can make
I have been adding Molyslip to every car engine and gearbox for nearly 50 years and the difference is noticeable within a few days with much quieter running and slightly better fuel economy due to its "surface plating" and you don't lose its effect at oil changes as it stays on those "plated" engine parts.Read full review

Molyslip engine treatment
Excellent product, engine running so much better with less noise. I would recommend when car is being serviced to put it in to maximise results. Protects from oil starvation and wear from cold starting. I've used this product for years without any problems. Best thing you could use in your engine and doesn't drain between services. 5++++++++Read full review

Believe in it, it seems to work well.
I do not say this product is better than expected, those are your words. I have used this product for many years and although we have to take it 'On Trust' I do think it helps the lubrication of my engines. In winter I do notice an improvement in the start up of the motors.Read full review

Perfect engineering lubricant
I have used Molyslip since 1962.I was present at it being tested at General Motors Holden.
I think it is the best oil additive ever invented.
Engines/gearboxes /Diffs run as smooth as silk.Read full review
