Smooth driving and EPA is the biggest saver and you will still do fast laps...I missed my fuel stop a few races ago so to be safe on fuel i cruised around using a lot less throttle that lap, i'd say a 3rd to a half less..out of interest i checked that lap time and it was only a 3rd of a second slower than my hard driven good laps.

pushing the GXII hard I can get 10 minutes so driving smooth 12 should be possible but to be honest its more fun going hard.

I'm also running the same plug and pipe as you in a mugen mbx6.

one other thing that will effect fuel usage is an over oiled air filter
