i top offed my tank last week, (even put premium in!) and reset the trip odomoter, and here i am with the needle past E, and 240 on the odo. I drive a stock CX (SRI) and no i dont drive the hell out of it. shouldnt i get around 45??? this adds up to about 24 mpg what causes this?

Many things can cause it, you will probably get worse gas mileage by using higher octane gas. It tends to evaporate faster. It could also be due to clogged injectors, a heavier weight motor oil, etc etc. There are a million things that can effect mileage, like letting your car idle for a long period of time, or driving it in the city more than the highway one week.

 

yep a million things... like low tire pressure, dirty air filter, anything that restricts the car from performing like it should... i would check those also.

 

yea i could use a new fuel filter. and watch spark plugs and **** have those been changed since you bough your car? fuel filter every 25k miles. about. i need to changhe mine and i need to get an intake or just a new filter. and wait for my swap.

 

assuming you have high mileage. your pistions might have a little blow-by and your valves may not be seating properly. have your compression check

 

I find that when your just cruising higher octane gas gives you better MPGs. I believe this is because you dont have to put quite as much load on the engine when gently accelerating, whereas low octanefuel you have to give it that little bit more gas when accelerating gently.

Ive seen it alot where cars with clogged air filters drink fuel and are less responsive

Id check that out first but like most eople have said theres a million things that can affect it and they all add up.
