Poor MPG

[Mr. Red Pony]

Give me some ideas.

I checked the spark plugs (normal wear, but still good) Changed the air filter (Dirty as fuck) and attempted to change the fuel filter (No external filter... Even though I picked on up from A-Z) Does the ECOTEC have a PCV valve?

I need some ideas..

what are you gettin now?

[Mr. Red Pony]

HUD says 24.5 per gallon but a tank only lasts 250ish. Was 350ish per tank. HUD read 33.5 per gallon.

prolly since you got that exhaust you dont drive like you should. keep it under 2k on normal road and 3k on highway. should raise it up a little bit.

There is an external filter. It's near the EVAP canister.

Nope right behind the fuel tank. Above the rear axle.

I looked there. I had it on a lift and looked all under it with no avail.
