I run 99 Ron (Shell VPower) and it loves every minute of it. I pay £1.02 per litre (£4.64 per gallon) that's $9.78 per gallon to you lot across the big lake...and it is worth it for me over the 95 ron fuel. So go fill yer boots with that cheap high octane fuel and remember how much we have to pay for it in the UK and it should make you feel better and buy the good stuff everytime without thinking it is expensive.
