LOL! Fair enough man. Just that there's sooo many factors into working out MPG manually (I mean, I try to do it). But say cruising at 60 compared with 70 uses something like 30% more fuel (not sure on exact values, but it is very significant from what I remember), many posts regarding Shell Optimax, BP Ultimate etc.
There's plenty of info about factors that affect fuel economy such as here, here, here and here
Not offcially read/heard anywhere to say performance mods = better fuel economy, but a bit of logical thinking suggests it would (e.g. more power for same revs etc.)
I'll see as well then when I get my Prolex IK!
BTW, what rate comission U getting from ProLex? :winky:
