Unleaded fuel in Rolls-Royce and Bentley vehicles in South Africa
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.
