Hi!

Im in the process of buying a 2013 honda fit with 140k miles from a friend; its been taken care of in its life and is very responsive in both gas and breaks, but ive noticed the mpg hovers around 26.6mpg when ive heard and seen others experience 30+mpg. with gas prices looking like theyre going to continue climbing (6.30/gallon in california) im trying to get the most out of my car for the time im spending using it. im up to date on oil changes, i just got some work done replacing a few gaskets/spark plugs/ various other tuneup activities and i wonder what i could be doing to make it even better. the AC doesnt blow cold either, if thats an issue anyones experienced and can give me some guidance on.

thanks!

 

AC could be lots of things. No freon, bad compressor clutch, bad relay, dead compressor. Bought mine with the AC not blowing cold. Was the compressor and just finished doing a full replacement AC system on it. But the easiest thing to check for is that relay. You can swap the AC relay with the radiator fan relay and verify if it is the relay.

For your MPG. I'm gonna bet most people are gonna recommend you do a valve adjustment. Other small things I could think of would be checking your air filter and maybe cleaning the mass air flow sensor. I drive my 2nd gen hard and am currently ranging around 31 mpg.

 

Is your fit an auto or a manual? For an auto, especially in city use, that’s normal. For a manual, that’s really low imo.

AC may be as simple as buying one of those recharge cans from a hardware/auto parts store and filling it back up. My Fit just needed a recharge five years ago and has been fine since.

 

Automobile efficiency isn't complicated.
1) Properly running engine and properly inflated tires.
2) Reduced weight -- don't carry extra junk in your trunk.
3) Reduced speed -- just because all your friends want to drive 10-20 mph above the speed limit, you don't have to.
4) Accelerate and decelerate smoothly and with anticipation for the conditions ahead of you. Coasting is your friend.

I have a lifetime (a bit over 5 years) average of 38.4 mpg in a 2010 Fit Sport A/T, with non-winter highway trips in the 42-44 mpg range.

 

This^^^. Exact same experience with my 2012 manual. Great advice.

 

thank you for the advice! i have a mechanic appointment coming up to see what the issue is ac wise, hoping theyll point me in the right direction. the air filters are definitely old, ill replace them and do some googling on mass air flow sensor. thanks!
