Valvemaster and Valvemaster Plus provide the best protection against valve seat recession after lead, while keeping the fuel system clean and providing excellent corrosion protection. Both Valvemaster and Valvemaster Plus contain Etha-Guard, an ethanol stabiliser to protect the fuel system against the corrosive effects of ethanol contained in fuel. Etha-Guard is effective in both E5 and E10 petrol, preventing acidity and corrosion, thereby protecting your vehicle’s fuel system.
The unique phosphorus based formulations provide the best possible protection in all driving conditions - including high speed motorway driving or towing, guarding against metal contact between valves and the soft valve seats - the job previously done by lead. Without such protection, engines may experience valve burning, loss of compression and engine failure. Classic sports cars engines in particular operate at higher revs, are often driven at sustained speed, and therefore require the level of protection that Valvemaster and Valvemaster Plus provide - something many other lead replacement products cannot offer.
Both products carry the endorsement of the Federation of British Historic Vehicle Clubs and have undergone independent screening to provide users with reassurance.

THE ETHANOL ISSUE
The standard grade of petrol supplied at all filling stations in the UK is Premium Unleaded 95 octane E5 (known as 95 E5). This grade of petrol contains 5% ethanol.
Super grade fuels of usually 97 to 99 octane typically, though not always, contain 5% ethanol.
The European Union Fuel Quality Directive introduced a specification in 2011 that petrol may contain up to 10% ethanol. This petrol is commonly known as E10.
E10 petrol is currently sold in France, Germany, Belgium and Finland, with other EU members looking to introduce it. The UK is on track to meet its target of 10% ethanol content in petrol by 2020.
The UK Government’s own analysis shows that there are around 1 million petrol cars registered in the UK that are not approved for use with E10, as well as a significant number of motorbikes and scooters. Many of these are classics, but around half are less than 25 years old.
Ethanol blended petrol is less harmful to the environment than unblended petrol, with less carbon monoxide emission produced. The disadvantage of ethanol blended petrol is that it isn’t suitable for all vehicles, especially older vehicles.
Ethanol blended petrol is acidic. In unapproved vehicles it can cause corrosion in the fuel system.
Valvemaster and Valvemaster Plus protect your vehicle from the harmful effects of ethanol in petrol.
