I run 99 ron in the UK. Inside the petrol cover it says 93 ron. Mine runs just brill, so I wouldn't change and only ever fill up with Shell VPower (never put anything else in the Xfire).

It's really funny hearing you lot over the "big lake" moan about petrol prices......Shell Vpower is about £1.01 per litre, thats about £4.59 per gallon at $1.99 to the £1 that is about $9.13 per gallon !!!!!!!!!!

so have a good laugh at us in the UK and I would swap petrol prices with you any day !!!
