Re: 98 octane petrol!!!
The Vee is absolutely designed to run on 98 RON - anything less and the ECU has to mess with the timing. However, not all supers were born equal.
My preference has always been to run on V-Power (and Opti) before it. For a while I swapped to Tesco, but I get consistently 0.5MPG less with that. Reckon it's down the the much higher proportion of bio-ethanol in the Tesco fuel!
Yep ... and furthermore there's a noticeable difference between the supers too.

Re: 98 octane petrol!!!
There is!
My drive when I used to commute in my Cup was regular and consistent.
Any time I switched to anything else I saw a drop from 37+ to less than 35.
Tesco 99? Don't even go there. Once and once only have I had to end a trackday early through running out of fuel, and that was running a brimmed tank of Tesco 99 slop.

Re: 98 octane petrol!!!
98 RON or higher as recommended on the tin. V-Power or Tesco 99 depending which is closer at refill time.
Take a look at the links below, make an interesting read ...

Re: Super Unleaded or Unleaded
It says 98ron recommended on the fuel filler cap for a reason imo. And I can tell the difference between normal 95 and vpower (99), and tbh its not that more expensive tbh. Its probably only a couple of quid difference on a fillup so no big deal its the cost of a pint.

Re: Super Unleaded or Unleaded
The nitro stuff? I bet that has interesting results if you did try. Its about 75%Methanol 15%Nitromethane 10%oil. They use similar stuff in dragsters!!
Renault recommend 98ron and say 95 can be used if 98 is not available. I cannot notice a difference, search on youtube there is a video where 5th gear i think it was found it can slighlty increase bhp in performance cars but make hardly no difference at all in smaller engines.

Re: Super Unleaded or Unleaded
Not entirely true. Depends on the fuel and who makes it. Super just has higher Octane rating which means less DET in higher performance cars.
