ok guys imjust wondering i have a 98 ej8 with an ls swap, and im getting around 275 miles to a full gas of tank, is this normal?

or should i be getting more?

motor is stock only has a short ram, header and full exhaust also running an obd1 ls ecu

any input will be greatly appreciate it

 

To calculate your average mpg, reset you trip meter and next time you fill up the tank to full, take the number of miles on the trip meter and divide by the gallons of gas it took to fill up.

Repeat this method anytime to get your avg. mpg.

The 1998 Civic gas tank capacity should be 11.9 U.S. gallons; however, you can't really tell the actual average mpg without using the trip meter and the number of gallons needed to fill the tank, since the gas remaining in the tank may vary when you fill up unless you ran it dry every time.

The 1998 Civic's average mpg is posted at this site.

However, YMMV (Your Mileage May Vary) depending on whether the car is automatic or manual, driving habits, etc.

For example, you traveled 275 miles, filled the tank all the way, and it stopped at 10 gallons, your avg. mpg would be 27.5 which would be close to the Civic's published avg. mpg at the above site for city driving. If this was principally Hwy driving, then your avg. mpg would be low in comparison.

275 seems to be very low for a full tank...... i get 350-375 per 9 gallons mostly stock z6 with i/h/e....

 

ok i get all that and i know im averaging about 27 mpg

but what i was trying to see is what is other ppl with the same set up that i have or similar to it they are averaging

 

Mention your driving style (speed racer vs grandma) as well as how much of your mileage is city versus highway driving. Without such details, gas mileage comparisons are meaningless.

 

is mainly regular driving and city driving and yes it includes lights and stop signs and i drive 30 miles a day


and no i dont drive like a grandma and im not a speed racer either
i race but i racemy crx at the track

 

yeah i make with my d16y8 around 270, mine is bad too right what can we do to save more gas?

 

oh is not about the saving of gas it was just a simple question, since in my dually i average around 23 mpg and thats with some things done to it like edge programmer andother stuff i know i can do 28 but im still working on the truck, on the one i just to have i was doing 29 but highway miles

 

he's not asking what his ej8 is getting. he's asking what an ls SHOULD be getting

that link could help as far as an ls motor should be getting, but you'd have to bend your numbers depending on the weight of the teg vs your civic and size of the gas tank

 

ushhh i find it out and my car is doing right and yours too bro so dont worry
