Castrol Classic Valvemaster with its unique phosphorus formula protects against valve seat recession under all driving conditions. Containing Etha-Guard ethanol stabiliser that protects and enables use of ethanol E5 and E10 petrol in classic cars, motorcycles and pre-1996 petrol vehicles. For use with 95, 97, 98, 99, or higher octane ethanol E5 and E10 petrol. Valvemaster is the recommended solution for cars and motorcycles requiring valve seat protection. The best protection after lead against valve seat recession Protects your engine under all driving conditions Keeps fuel systems clean Protects against corrosion 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 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. "Independent research shows phosphorous offers the best engine protection, and Valvemaster & trade; ensures consistent performance for engines originally designed to run on leaded fuel."

Castrol Classic Valvemaster Plus with its unique phosphorus formula provides the ultimate protection against valve seat recession. Vavemaster Plus contains Octimise-Plus friction modifier for increased acceleration and economy, increasing acceleration by up to 3% and increasing economy by up to 2%. It also contains Etha-Guard ethanol stabiliser, enabling the use of Ethanol E5 and E10 petrol, preventing acidity, protecting against corrosion and keeping the fuel system clean. Endorsed by the FBHVC, Valvemaster™ Plus with a unique phosphorus formulation was shown to offer the highest level of protection of all products tested. Valvemaster Plus can be used with 95, 97, 98, 99 or higher octane rated petrol containing E5 or E10 ethanol. The best protection after lead against valve seat recession Increases fuel economy by up to 2% Protects your engine under all driving conditions Keeps fuel systems clean Protects against corrosion Increases acceleration by up to 3% 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.

"Independent research shows phosphorous offers the best engine protection, and Valvemaster™ ensures consistent performance for engines originally designed to run on leaded fuel." Valvemaster Plus contains Octimise-Plus, a friction modifier that increases acceleration and increases fuel economy. Valvemaster Plus increases acceleration by up to 3% and increases fuel economy by up to 2%. Valvemaster Plus can be used with whichever octane rated fuel your classic vehicle performs best on: 95, 97, 98, 99 or even higher octane rated petrol, both regular and E5 or E10 ethanol. How does it work? In a typical engine, about 25% of fuel input is converted to useful work 75% of energy is wasted Friction modifiers work by reducing the mechanical losses Octimise-Plus has 2 modes of action. Fuel mixing with the lubricating oil at the piston ring and liner leads to an immediate change in the co-efficient of friction at this point. Fuel mixed with the lubricant can migrate into the sump altering the bulk lubricant properties for a long term effect. Octimise-Plus gives the following instantaneous benefits: 2% improvement in fuel economy 3% improvement in acceleration If you are unsure as to which oil type or additive you require please visit Castrol Classic Oil Finder
ETHANOLMATE is the leading product for use with ethanol-containing petrol - E10 and E5. Designed as a corrosion inhibitor, fuel stability improver and biocide. Added to the tank when re-fueling, ETHANOLMATE helps prevent fuel degradation in storage in the fuel tank. It provides excellent protection against fuel system corrosion due to increased acidity which can occur when petrol containing ethanol is stored for any length of time e.g. in vehicles over winter. Dispensed from a plastic bottle (with graduated optic) at refuelling time this is the simple way to protect your vehicle from the harmful effects of ethanol. Prevents acid formation due to deterioration of the ethanol component in fuel. Protects against acid corrosion in metal fuel line components. Protects against gum and resin build-up and carbon deposits. Cleans carburettors, injectors, filters and fuel lines of existing deposits. It can improve driveability, increase fuel economy, restore power and reduce emissions. Suitable for use in 2 and 4-stroke engines. It can be used with leaded petrol, LRP, octane boosters and catalytic converters.Most engines manufactured prior to 1996 would benefit from the use of ETHANOLMATE. Bottles are 250ml which will treat 250 litres of fuel (approx. 54 gallons).Please note: Bottle labels may vary by batch, content is identical.
