what the hell is wrong with my fuel economy? Im still avg. approx 20mpg however my tank is not lasting the normal 300 - 330 miles like it use to. It's barely getting me to 260, barely. Can this be because of the winter we're having here in the northeast? too much ethanol in the fuel? I dont get it. I cleaned out my Injen filters August 2010 so they should still be good. Any ideas?

 

Did you change gas stations? it could be the fuel, are you driving any differntly?

 

I'm barely getting 200miles out of a full tank lol

 

I have started trying to avoid the stations I know that use an ethanol blend. Not sure how much it really helps though.

 

Fun fact: I've never gotten 20 mpg out of a tank since owning the car (8 months). Closest I got was 19.8 on my last tank. Currently I'm at 17.8. So I would love getting 20.

 

Mine stays around 22. I don't have my foot in it all the time, that might be helping a bit.

 

I've never past 19 mpg... always around 17-18. 15-17mpg when I have my intakes on.

This is about 80% city driving.

 

It can be the winter blend of gas as well. It can decrease gas mileage.

 

Mine's about 19.2 - 20. And I get maybe 340-380 per tank. Getting 20mpg and only getting 240 per tank seems off.

Even if it was an E-blend, you'd see it reflected in your MPG average as well. Try resetting your fuel economy numbers and riding out an entire tank to have it re-adjust?

I try to stick with places like Chevron and avoid places like Arco. I feel like there's a reason Arco's gas is always 10-30 cents cheaper than everywhere else.

 

Definitely.

 

Full tank : 470 km which is 290 in miles .
mine is 5AT .

 

I guess we'll see when warmer weather comes the fuel changes..
