ive been getting about 23mpg in my 95 civic ex sedan, i run it generally til the gauge reads empty, although its a 12 gallon tank i believe i never seem to put much more then 9 gallons in it, its also an auto, come spring im manual swapping it accumulating parts at the minute, i was read and ive decided new injectors, fuel filter and maybe a fuel pump, i was wondering what else i can do to help my mpg a bit, is it worth it to get premium, and what stations should i go to? near me theres delta, hess and shell mostly

 

i get roughly 28-29mpgs. got a 93 civic si. i use regular gas, i have tried both premium and regular and get same gas mileage. thinking i should be getting around 35 mpgs tho. i am also interested in any improvements

 

Remember:
1) It's a vehicle from 1995 (It's 2013 now, that's 18 years)
2) What you're getting is just about right, even with a full tune-up.
3) The best thing to do is to swap in a VX (92-95 Dseries) or a lesser HX (96-00) engine. These make:



Going premium would be retarded in a way.
Common sense, you want to get BETTER gas mileage, to save money. So if you get premium instead of regular, you will be spending more money in the long run.
Civic's are 'civil/civilian' vehicles, they were designed (stock) for 87 octane, not for high octane and high performance.

 

There you have it now people... 18 year old cars that have never been refreshed or even if they have.... dont expect them to drive and act like they were when they were new.

 

Is the ecu tuned to run premium? If not your throwing away 20 cents a gallon

 

I drive about 75% highway so maybe a little better, screw the swap to a lower model engine I'm not that concerned. about the MPG...prob best thing would be limiting the use of the right pedal.....and maybe more cruise control
