Thanks for the advice roadwarrior I hadn't thought about the flex pipes, might be a good opportunity to upgrade to braided.

Mr Wilks, no its a 2.5 e85, I can never seem to get more than 245 fŕom a full tank.

Was the run you did punctuated by lots of stop/start driving? That will ruin it as well :cry:

40mpg on a run?

I used to get 33mpg tops on my E86 3.0si on runs @70mph using VPower.
I also get near 40mpg on a steady run in the Coupe

Your snapshot doesn’t show your mpg fella... :?

Unless you are trying to illustrate you are getting 420 odd miles out of a tank?

What does your trip computer say?

Have to concur that driving style plays a huge factor in overall fuel economy.
It's actually become a bit of a mission in the zed having had use of a Tesla and a Skoda hybrid in the past.
I regularly skip gears; 1-3-5,6 etc. I coast for miles to red lights and junctions which irritates the living hell out of the Dutch drivers here in Holland! :lol: I also do 100kmh on the snelweg and stick to speed limits in town which also surprisingly seems to irritate the Dutchies. :P
All in all, however much I irritate other road users, I save fuel and sponds and regularly achieve between 35-45 mpg on any given run.
I'm not as anally retentive as to measure my monthly/yearly fuel costs and enjoy giving it the beans once in a while which cumulatively, for me is very satisfying. :thumbsup:

Been out earlier in Si coupe , auto N52 & over 27 miles mixed mway & backroads average after zeroing when i left home was 27.6mpg which i was pretty pleased with :driving: can't compare with manual N52 as they are notably better on mpg
Id also expect real world figures to be down on those shown on car computer
