quality protection against valve damage
top rated product from a trusted manufacturer. One 25 ml bottle treats 250 litres of unleaded petrol so very economical protection against possible expensive engine damage on a classic vehicle.

I am unable to recommend or decry this product
My car needs such a product. I was about to run out of it, so I bought some more.
Do I know if it is of good quality? Is it good value. How am I to know?????
Two absolutely stupid 'yes or no' options to stupid questions.
Maybe this product damages my car's engine, so much so that the engine needs replacing after 5 years - how am I to know??? How can I give it a valid star rating??

Help for old engines
My 1968 Morris has hardened valve seats, and in theory is ok to run on unleaded. I use Valvemaster as additional insurance, given that I use the car a lot and want to give it all the help I can with modern ethanol containing petrol. Read full review

Classic Valvemaster works for my Beetle
I have always used Classic Valvemaster in the fuel of my 1967 VW Beetle and it has always performed well and no signs of any problems with rubber hoses/seals with new ethanol loaded fuel.

Good item, would recommend.
This product is a great additive for unleaded petrol, to use in a car that was designed for 4-star fuel. I've used it for many years without issues.
