If you think your car uses to much gas and is expensive to fill up you clearly.cannot afford the car your best bet is get rid of the g and get some like a civic or.camary

 

I had a civic. And I am trying to get better mpg. Stop bugging out.

As I said before. I knew what I was getting myself into. Just trying to improve mpgs. Why don't you read what I wrote

 

Intake and exhaust improvements are worth it, but fairly negligible (1-3?) when it comes to MPG improvement. And, I could be wrong on this, but if you're going to do one you might as well do the other. The intake helps the car breathe in and the exhaust helps it breathe out, you really should get them both to see improvements.

 

Ding, ding, ding...!

 

I was a bit surprised at how bad the gas mileage was on the car ('11 G37X coupe)

I only drive on the weekends for the most part, so I wasn't worried, but I went from filling my tank once every five weeks or so, to having to fill up every two weeks.

Same amount of driving.

I was driving a Pontiac G6 GT so it's not like I came from a 4 cylinder.

However, if you're going to shell out 40k+ for a car, the extra $$ to put gas in it shouldn't be messing up your budget. If it is, then you aren't living within your means. I'm not trying to say that's your case, but in general, once you spend a certain amount for a car, putting gas in it shouldn't be a big deal.

 

You go ahead and try to use the whole 20 gal tank. Please tell us how that goes.

 

I can't imagine this car getting worse mileage than my 5.7L camaro did ~13-15 city, 21-23 hwy (with 80K miles on the odo). About the only time I'd really get into the throttle was on on/off ramps, other than that, gramma like acceleration, but 10 over the speed limit usually.

Most times, if coming up to a light, rather than downshifting (think sequential gear box) through each gear, just stick in neutral and coast up to the light. If the car ahead moves a few feet, stay put until the light actually turns green. Skipping gears might help too, but be sure to rev match (ie, 1st to 3rd, let the rpms drop enough).

Do folks notice better mpg running premium fuel?

 

Change your driving habit (Y)

 

I imagine he pushed his car.

 

I dont understand how an intake would help with gas mileage.. more air means you need more fuel or you will lean out. Sooo ya kinda makes no sense. I think its more that people drive slower with intake because it sounds nicer at a lower rpm than stock lol.

 

Haha, civic guys! I drove slow in the civic and i got only 22 mpgs, but when i started driving more aggressive, i got so many more! 26mpgs!

That doesnt work on the g37 haha.

so would the intake improve my gas milage? or would it use up more fuel? Intake and exhaust seems like a bit too much right now. I just got the car 2 days ago. i dont want to dish out a thousand right away but i might spend that 400 for the intake if it would pay itself off in the long run

 

You only got 22 to 26 in your Civic? Either there was something wrong with your car or your foot...

 

I got 27 mpg in my 2009 lancer gts. It only put out 168 hp crank but it still was a great econo car.

 

Uhmm don't drive best way to improve gas mileage.

 

Ok, ok, ok. If you want better fuel economy, learn to drive better. It's your driving habits, I promise. They make a huge difference. No, I don't mean drive like Grandma. In fact, she probably does a bad job of conserving fuel. Learn how to conserve fuel, then do it.

Want something that doesn't require that you change? Ok, get a lightweight underdriven pulley set. It'll save you some fuel, and contrary to what the next guy is probably going to post, they aren't the devil and won't hurt your vehicle in any way. Get different tires. Yes, some are made with lower rolling resistance and will help your fuel economy. Yea, you'll sacrifice some traction for it, but odds are you won't need that traction if you're worried about fuel economy. You can also increase the air pressure in your tires. Up to about 45 and you'll be fine. Yea, a little harsher ride, but after 5 minutes, you won't notice it anymore. Again, contrary to the next guy's post, higher air pressure won't make your tires fall apart, or wear horribly. I've run with tires up to 50PSI before with no abnormal tire wear for the life of the tires.

Check out websites oriented around increasing fuel economy. There are tons of them, just search.
