Lead replacement additive to protect against valve seat recession
Developed to lubricate and protect soft valve seats from wear, allowing your vehicle to run safely on modern, unleaded petrol. This product is recommended for classic and vintage cars still on the road which are running on unleaded petrol whilst having been designed to run on leaded fuel. It is designed as a replacement for lead in petrol because of the arbitrary market requirement for environmentally friendly fuel formulations. A 25ml shot is recommended for use in 25L of petrol.
