Goscor Engines divisions announced that the phasing out of leaded petrol would not be a problem for Robin Subaru engines.
They recommend that engine owners decide on the most appropriate unleaded petrol (ULP) or lead replacement (LRP) petrol using only that petrol grade for their engines. It would not be a good idea to keep on switching between the different grades available.
If for some reason the grade of fuel used needs to be changed, users will have to take their engines in to the nearest service center for the engine to be de-coked. It is a simple procedure where the mechanic removes the cylinder head in order to remove all the carbon from the cylinder head to back lap the valves.
It is not advisable that engine owners do it themselves especially when service warranties are still valid. Existing Robin Subaru engine warranties will stay in tact during the phasing out of leaded fuel on the condition that engine owners submit engines at service centers for the de-coking of engines.
