Where I live (in the sticks) there isn't a Shell garage within about 20 miles of me. Of course, the Turbo needs a wee drink now, and the nearest Esso sells 97 RON unleaded. I know it says you should put 98 in and I would only put 95 if if there was no other fuel ... but is 97 going to be OK in lieu of 98?

I'd put anything in other than fresh air [
] I would imagine that it'll be fine with the 97 and when passing fill on V-power - I hope so as thats what I do [] My nearest Shell station is about a simialr distance, so I time fill ups with me going that direction, by eck! I'm passing by it tomorrow [] I find the cars use a lot of fuel, especially when you've just had them [] [8D] garyw

In my experience 97 or 98 octane makes not a scrap of difference. Shell pulled out of our area years ago - our nearest station is now 40 miles away. I tend to use BP Stations where possible hereabouts and stick to higher volume sites with busy throughput as I've found quality at smaller sites can sometimes be erratic. The engine comes with a brilliant software package and includes knock sensors that guard against damage from poor fuels. In extremes, it retards ignition and prevents detonation. You then notice some reduced engine performance, but it readjusts to optimise better fuel later. [] Hope this helps. Regards, Clive.

Great link and interesting, but as you say Alan, it's an old one and Optimax is not now available. [8|] There's loads on the interweb regarding Shell v BP. I would certainly use Shell when available and at a sensible cost, but wouldn't drive miles out of my way or pay a large premium to get it. The OP asked if 97 is OK in the absence of 98. It'll be fine - in the real world, I can't discern any difference. The car will also run OK on 95 octane if necessary. Getting a tankful of clean burning fuel is the main priority IMHO. See you all tomorrow! [] Regards, Clive.

don't have an awful lot of choice around here other than to use Tescos. used it in all my Porsches and have never had any trouble whats so ever. i will however top up with shell when ever i happen to be passing one but theres no way i'm driving miles out of my way just for petrol.
V-Power = Son of Optimax.........[
] It would seem that higher octane fuel is desirable, particularly in turbocharged engines, as it provides for a much more controllable burn. But,with the all singing all dancing computers these days, they will run on most things short of chip fat I imagine!
I always use Tesco Momentum 99; it's available in Peterborough & Sleaford stores.
