Re: 110 Octane race fuel
Before we owned the Crossfire Roadster we used to have a tuned Mini Copper S turning out 230 BHP, the tuning company who carried this modification out told me to use Super Unleaded petrol, in the UK this ranges from 97 to 100 Octane. The main reason for using this grade was that the increased supercharger boost could potentially lean off the mixture and using 100 octane prevented damage to the pistons.
One thing I have noticed as a knock on effect is that our Mini ran smoother with better pick-up when running Super Unleaded (97 to 100) fuel. Yes it costs more but we only do 4,000 miles a year in the Crossfire so perhaps the additional cost is offset by smoother running, reduced engine wear and slightly better performance?
OK, perhaps the 110 is a bridge too far but what are your thoughts on running 100 octane in the Crossfire.
We can only purchase Regular @ 95 octane or Super Unleaded @ 97 to 100 octane in the UK.
