Hello All....97 civic LX
 

Hello,

My name is Jimmy Criswell. I just thought I would introduce myself to everyone. I just bought a 97 civic with 202,000 miles on it. Has a slight stumble occassionally on acceleration but runs exceptional other than that. So far I have only gone through one tank and got 39.97. I aired the tires up to 46. Max says 44...how far can you push this? I changed over to Mobil one synthetic 5W-30 although I am thinking of changing to a lower viscocity higher caliber oil. Has a stock air filter that is slightly dirty.

My beginning goal is to get up to the 45 range. I have begun practicing some of the techniques mentioned here starting about 2 years ago with my Rav4 which I averaged 31 mpg in.

What suggestions are there to improve mileage to this point without making major adjustments to the car as my budget is very limited at this point.

Welcome!

Try disconnecting your O2 sensor, and see if the acceleration stumble stops. If so, it's probably your O2 sensor.

Welcome... what cbaber said... and also... what transmission do you have, auto or manual?

It is an automatic.

what kind of daily commute do you have?

If its mainly city driving - weight savings will have a bigger impact on mpg. Plus most of these are FREE
1)remove spare tire, replace with a bottle of "fix a flat" or something similar
2)remove back seat
3)remove passenger seat if you dont drive with anybody.
4swap out a smaller battery
5 removing the power steering is also free, this gave me a solid 3mpg bump.

if youre commute is mostly highway - aero mods will have a bigger effect on mpg
1)upper grill block
2) lower grill block
3)side mirror deletes
4)side skirts
5)front wheel covers
6)rear wheel covers
