To be honest, i've ran on 95 at times...... (not for a long time) and you don't really notice the difference. THere is a % power output loss. its in one of the faqs, but will run ok on 95......
so can you always top up with 95? will it not cause any damage as i thought it was not recommended as it can cause problems?
It'll never cause damage!! It's just that to get the most out of a sports car, they recommend you use a higher octane fuel.
