KuroLily Posted October 24, 2021 Share Posted October 24, 2021 Just a quick one, really - making sure I'm doing the right thing (Or not, I'll hopefully soon find out). Recently bought myself a GB270, so a Hawkeye WRX with a PPP and a few extras, car is completely stock as far as I can tell on the stock power (270ish BHP) My question is what should I be fuelling this with, I've always been under the impression I'd need super unleaded and have done so with Tesco Momentum, only whilst filling up today I've noticed the fuel cap specifically states Regular Fuel only and not to use anything higher... So... what should I actually be using and would it harm me to continue using 98/99RON fuel or drop down to 95 Regular? Quote Link to comment Share on other sites More sharing options...
Linx Posted October 24, 2021 Share Posted October 24, 2021 It certainly wont harm it to run on 98 RON and has the benifit of being E5 and not E10. So kinder on the fuel system. Quote Link to comment Share on other sites More sharing options...
Jay762 Posted October 26, 2021 Share Posted October 26, 2021 If your car was running fine I would continue to use the superunleaded 👍 E5 not E10 and some of them, eg Shell, have cleaners in them Quote Link to comment Share on other sites More sharing options...
