My 900-S has an 8-valve B201 engine and runs fine, but here in Australia, leaded-replacement fuel (called 'LRP') is considerably more expensive than standard unleaded fuel. The price difference is generally between 3 to five cents per litre.
I've asked a few people but nobody seems to have a conclusive answer... Has anyone successfully run a B201 engine with unleaded fuel?
If not with standard unleaded fuel, how about with higher-octane 'premium' unleaded? I've got no idea what the octane ratings of our fuels are here in Oz, but they'd probably be similar to what's available in the US and Europe, with differences in whether or not LRP and premium fuels are available.
I'm tempted to try the engine with mixture of half-LRP and half-unleaded (standard ULP) to see what happens, and move on from there.
