- leaded petrol
- Until the advent of exhaust catalyst equipped vehicles in the early 1990s, leaded petrol in 4* of 97 octane was the main form of petrol in the UK. Tetra ethyl or tetra methyl lead additives were used as a simple means of boosting octane and providing the necessary lubrication to prevent excessive wear of cylinder head valve seats. Leaded petrol was banned in the EU from the start of 2000 and for a while Lead Replacement Petrol (LRP) was available in the UK until dwindling demand saw it largely disappear in 2004.
