Unleaded fuel in Rolls-Royce & Bentley vehicles in South
From January, 2006, leaded petrol will be phased out in South
Africa and new octane grades introduced. This important development
is part of a process of aligning South African fuel standards
with international fuel specifications and vehicle technology
requirements. It will also, over time, promote improved air quality
and a healthier environment in South Africa. From this time, the
current 97 RON leaded petrol available in coastal regions will
be replaced by a 95 RON lead replacement petrol (LRP).
Fuel available in South Africa will now be:
91, 93 and 95 unleaded (inland and coast)
93 Lead Replacement Fuel (Inland), 95 Lead Replacement Fuel (Coast)
The advice from all over the world is consistent, Rolls Royce
motor vehicles can use unleaded petrol. The vehicles will also
run equally well on the lead replacement petrol (LRP).
If your vehicle has been set up for 98 (or 100) octane fuel,
the engine may exhibit pinging with these lower octane fuels.
In this case the timing will need to be retarded (3 degrees) -
consult your service agent if required.
