Castrol valvemaster fuel additive.

Bought this lead replacement additive as I have a 1933 Austin 7 which has 'soft' valves and would suffer if used on todays unleaded petrol.
The product arrived well packed and quickly.
Instructions on the bottle are good, and getting the right dosage (for 5 gallon in my case) is very easy.
Enough for about five or more doses so might be enough for appoaching a years worth of driving.

Have used once now so a bit too early to give an accurate assesment but know of others who use this product and they are happy with it.Read full review

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??

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.

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.

This is a great product which I have been using for many years. One of the bottles was for a friend, so I now have him using it.

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.
