The mpg guage is actually a vacuum guage with a calibrated "mpg" face. In theory, If you hold the vacuum above 12Hg in or so, then that translates to "economical driving mode".Normal car vacuum at idle is 18-21 Hg in(depending on your altitude). Floor your pedal and u get near zero vacuum in the intake manifold, that means lotta gas wasted.true, i never gave that any thought.
is there anyway of installing a mpg counter lol
would be ideal for eco driving as i do alot of it.
Nope no factory mats for me hahadon't your mats have the hole for the clips on the floor to come thru? mine never move
