Lead Replacement Petrol

LRP was introduced for use in petrol (spark ignition) engined vehicles as a direct replacement for the now obsolete, 4* Leaded Petrol.

LRP has same octane rating as the (now obsolete) 4* leaded grade and so no alterations to the ignition setting should be required. In addition LRP contains potassium based anti wear additive to help protect the engine from exhaust valve/seat wear.

LRP is recommended for use in vehicles, which previously used 4*. Leaded Petrol but is not recommended for vehicles fitted with a catalytic converter nor for continuous use in vehicles used for racing, towing or driving at high speeds for long periods of time.

In cases where such driving styles are required the vehicle manufacturer should be consulted as to a longer-term remedy, such as having hardened valve/seats fitted.

Lead Replacement Petrol contains a detergent additive to help keep carburettors; fuel injectors and inlet valves clean, maintaining driveability and performance.
