mortzz Posted November 21, 2019 Author Report Share Posted November 21, 2019 Thanks guys I do know abit about mapping and at lowish revs normal unleaded should be fine but you would need super on a track day as it's all about the dreaded knock and the mixture being weak as I'm from the Turbo background so I take it Porsche mapped the boxster for 98 in mind , so my thoughts are if ya not giving it right foot 24/7 .. 95 ton should be ok but you guys know alot more than me about this engine..

Liberty Posted November 21, 2019 Report Share Posted November 21, 2019 I’ve tried the cheapest but don’t you get more miles from the higher Ron fuel ⛽️ And doesn’t your car feel better or maybe I’m being lied to by my little beauty... Link to comment Share on other sites More sharing options...

Scubaregs Posted November 21, 2019 Report Share Posted November 21, 2019 Always had Tesco momentum in the Porsche. My GT86 definitely gave better mpg on the higher ron, tested over the same work commute over a couple of months. Link to comment Share on other sites More sharing options...

Can't say I've noticed any difference with either. I ran it pretty exclusively on Tesco momentum for the first 18 months or so. Link to comment Share on other sites More sharing options...

CAZ Posted November 21, 2019 Report Share Posted November 21, 2019 Was told when I bought my 987 from Guv's on here that my car doesn't actually like the expensive stuff and runs better on the ordinary. Link to comment Share on other sites More sharing options...

Mattman42 Posted November 21, 2019 Report Share Posted November 21, 2019 Super unleaded for me - but not a 986 - does give slightly better mpg and for the amount of miles I do, the difference is minor in the overall scheme of things Link to comment Share on other sites More sharing options...
BTM520 Posted November 21, 2019 Report Share Posted November 21, 2019 When I first got it I was using 99Ron Tesco. But back to using their normal fuel.... Link to comment Share on other sites More sharing options...

My wife to be said something similar when I first met her - turns out she runs a lot better on the expensive stuff 🙄🙄 Link to comment Share on other sites More sharing options...
½cwt Posted November 21, 2019 Report Share Posted November 21, 2019 Have to admit I'm a sucker for V-power. Dates back to when my Impreza Turbos definitely responded well to what was then Optimax and gave better economy which matched the price difference. Took less time on the throttle to get to speed so average throttle opening was smaller may be, but could be total bo***cks) Always felt more satisfying with the expensive stuff anyway. No idea if the effect is the same with a n/a Porsche as I've not run it on 95. Link to comment Share on other sites More sharing options...
topradio Posted November 21, 2019 Report Share Posted November 21, 2019 Just after I bought the 986 in 1998 I took it on a road trip to Italy for a wedding. On entering the country I pulled up at a petrol station and asked the attendant to fill it up with super. He informed me that it wouldn't be available anywhere in the country. I expressed my surprise in no uncertain terms that the in the home of Ferrari you could only buy 95 ron. Link to comment Share on other sites More sharing options...
usman10316 Posted November 21, 2019 Report Share Posted November 21, 2019 I either use Tesco Momentum or Shell V Power in mine. I did use Morissons once, I had some fuelling error on my code reader, cleared the codes, filled up with v power and hasn't come back again. So I learnt my lesson.

GmanB Posted November 21, 2019 Report Share Posted November 21, 2019 On my 88 miles round trip to work I get 2 mpg more from Momentum over Tesco cheapo, so it works out more economical to buy premium. It doesn't mean that all premium brands are better, it just means between tesco variants, there is a difference ("Every little helps"). Performance wise, yes it feels better. Is that a placebo? Maybe. Personally, my car feels much better on Esso super, which is around 10-15 pence more expensive than Momentum (probably near v-power price). Try a few different fuels and see what you prefer. I believe the ECU adjusts things as necessary to accommodate different octane levels. Link to comment Share on other sites More sharing options...
