My MPG seems to be fluctuating a lot, despite my trips being the same - I once hit 41-42ish, but my last fill was barely 35...its weird, because the trip is generally the same - from my house, its about a mile or two (engine warms up in this time), and then a lot of hills to school...
The hills I drop to neutral, generally 40-45ish at the peaks and a max of 60 on the downhill, then rev match (or at least try to, no tach...yet) and let the speed bleed off to around 40ish when I get to the top of the hill, but sometimes lower, as the car doesn't force itself to downshift until I drop below 30mph.
Anyways, maybe its just me or the weather, as its getting colder now...and if its me, the scanguage should come in tomorrow.
I just brought it in for an inspection and oil change today as well.
And how do I get the sig? Or does that just come with time...
