GazB Posted April 17, 2008 Share Posted April 17, 2008 but it does return more smiles for your miles (how cheezy is that ) :innocent: About 4/5 per gallon on strip normal driving i don't do very often long runs for me are down to keniworth and i normaly use 1/2 a tank of 97ron there and back if traffic on M42 permits which is a 130 mile round trip So 130 mile cost about £35 thats 27p per mile. Not that bad really as i only do this type of run 4 times a year, the rest of the time it's 4/5 per gallon. But i agree with the 'cheezy comment above Quote Link to comment Share on other sites More sharing options...
dannysupratt Posted April 17, 2008 Share Posted April 17, 2008 I have a uk manual which has bpu i get about 150 miles to £40, thats with a mixture of fast and normal driving, but on a long motorway run it will do about 200miles Quote Link to comment Share on other sites More sharing options...
RiceRocket Posted April 17, 2008 Share Posted April 17, 2008 I think the summary is: J-spec NA = normal unleaded UK TT = normal unleaded but better on super unleaded J-spec TT = only super unleaded unless remapped Also using super unleaded will decrease chance of detonation Quote Link to comment Share on other sites More sharing options...

I usually save some pennies each time by using 95 RON. It still puts Boxsters to shame, so I'm happy I thought all J-specs ran better on super than on normal, not just the TTs?

Alex C Posted April 17, 2008 Share Posted April 17, 2008 When I got to Marham... that was a different story; 80lt in 120 miles I meant to post about my fuel consumption at Marham. 49 miles used approx 40 litres of petrol hence I had to go and fill up....5.6Mpg:blink: Quote Link to comment Share on other sites More sharing options...
