I have a 98 Honda Accord LX 2.3L VTEC, and I want to add some parts to improve the performance, and MPG. I also don't want to spend very much either, I'm still in Highschool, so I don't have alot of money to spend. And my Grand-P's car is a 02 Honda Accord EXi with a 3.0L V6, and he would like to know how to improve his MPG.

 

The only way to improve MPG is to keep your tires inflated, your windows up and your A/C off. Any aftermarket product that claims to improve MPG is probably junk. Properly maintaing your vehicle will do more than anything. We have had countless MPG threads if you don't know which maintenance I speak of, try a search. Keeping the EGR valve clean, using seafoam to clean carbon deposits, and utilizing no throttle coasting above 1100 RPM (when no fuel is being injected into the cylinders) will help give you a boost.

If you don't have any money to spend on gas, why not sell your car and buy something more economical?

 

I don't have to pay for my gas and stuff, but I'm a bit broke. And I also get 27 miles to the gallon, thats, a/c off, windows down, and sunroof open.

 

Also, if I sell my car, and get another one thats more economical, it would cost a lot to buy, and would save me that much money. It would take years to pay the difference.

 

I'm talking like a 92 Civic CX Hatchback dude, not a 2005 Prius.

27 MPG around town is about normal for an F23. I assume you're not doing much highway being in HS. I get 27-28 highway and 19-20 in my V6 when it's running well.

 

My Grand-P gets 24 mpg and his driving is highway/city driving. Also, if I get another vheicle, they won't let me get anything older than a 2000.

 

You could lighten the car but that would be expensive...lighter rims, carbon fiber hood, tear out the seats, carbon fiber trunk, throw away that spare tire and associated tooling...etc...or walk when possible

 

Yeah sure! I go about 30 miles or more a day, I can't walk. And I could lighten it, but like you said it would be really expensive.

 

intake, exhaust, seafoam, drive slow

 

My SRI did affect MPG one bit, I had hoped it would Theoretically you'd think it would :dunno:
