hey everyone,

i'm new to the civic scene but were involved in a bit of import tuning prior. for the 97-99 civic HX, can they be leaned out (with a AFC or fuel controller and wideband for monitoring) to get better gas mileage?
i know the HX is already one of the best mpg civic from the factory. but i was curious if anyone had tried it or if that was even possible at all?

thanks for any feedbacks

 

Leaning an engine will cause damage to it. There are better ways to increase a cars MPG.

 

Pump your tires up to the max PSI, do a tune up, turn your car off at red lights, coast as much as possible, and drive like a granny and you should easily be able to get over 40mpg

 

doesnt starting ur car use more gas than just sitting for a minute? atleast thats what my dad told my sisters friend when i was like 12

 

^ Depends on how long it's off for. At a typical red light, you should save some fuel, but this does put a bit more wear on the starter...so like everything, it's a compromise.

Oh on other thing, not slowing down as much for turns will help too. That way you have to accelerate a little as possible. Although passenger may or may not like this lol.

 

But then you put more wear and tear on the tires and suspension components. Which defeats the purpose of saving gas.

 

How does that defeat the purpose of good gas mileage? By not really saving money in the long run?

Are you honestly going to have this car long enough that you're going to replace suspension parts more than once? That stuff lasts a looong time, even with moderate abuse.

And the less you slow down, the less you use your brakes, the less strain you put on the engine by making it accelerate.....

Oh and don't run the A/C, that'll help for sure

 

Make sure to coast in gear and not in neutral also
