Vehicles built before 1980 and not
shown on the NAAMSA database
The NAAMSA compatibility database details fuel requirements for vehicles
registered from approximately 1980.
Vehicles registered before 1980 and where manufacturer advice is not available
should use an available 93/95 RON Lead Replacement Petrol (LRP) or Unleaded
Petrol with suitable bottled anti VSR additive when operating at sustained high
engine speed.
In the case of vehicles currently using 97 RON leaded petrol, an engine ignition
timing adjustment may be necessary to operate on 95 RON petrol. Consult your
local vehicle service outlet for further advice.
On reconditioning of the engine or engine cylinder head, fitment of unleaded
petrol compatible valve seat inserts should be considered.
