Valvemaster 2 in 1 Formula is a 250ml additive for classic and older petrol engines that were built for leaded fuel. It does two jobs: a lead replacement that protects against valve seat recession, and an ethanol stabiliser so the car can run on today's E5 or E10 petrol. One bottle treats 250 litres of fuel, and the formula is endorsed by the Federation of British Historic Vehicle Clubs.

Good to know

• Does my car need a lead replacement? Engines built for leaded petrol can suffer valve seat recession on unleaded unless their valve seats have been hardened; if you don't know the engine's history, treat it as unhardened.
• Why does ethanol matter in an old car? Ethanol in petrol attracts water and can corrode older fuel systems and perish older rubber hoses and seals; the stabiliser in this formula is there to counter that.
• How much do I add? One bottle treats 250 litres, so measure the dose to the amount of fuel you are putting in at each fill rather than tipping in a whole bottle every time.

Which one?

For a petrol car that only needs its carburettor and injectors kept clean, the STP Petrol Treatment – 200ml (51200EN) does that job; for water in the fuel and cold starts, the Wynns Dry Fuel Professional Additive – 325ml (71851). Neither is on our site yet.
