My car is a 2001 Accord V6 and it has 80,000 miles on it. It used to get 320 miles per fill up highway/local on average. Recently I havent been over 300 miles, now on average I get about 280. Im guessing the spark plugs have gotten old and need replacement after 80k. Any other suggestions?

plug wires, dirty injectors not getting good enough fuel atomization...

if its an automatic that the fluid isnt filled correctly, it could be transmission slip or the torque converter not locking up quite right, or you could just plain be driving with a foot of lead

could be your O2 sensor check out www.autohausaz.com read auto repair #10 Bosch actually recommends a change at 100,000

My '97 V6 doesn't get very spectacular mileage either. It gets around 29-30 on the highway at best. And just driving around town in the winter, I get about 17-20mpg, which may be partly because I let the car warm up for 5-10 minutes before I drive it. I've always used 88 octane just because the next one down is 85.5, but with the recent price hike i just switched to 85.5. I have used injector cleaner, probably 6 months ago. Everything else should be in good condition. It's got 95K miles on the clock. Anyone else get mileage this bad??

I have an 00' AV6 and i can get 380-400 miles per fill up on the highway and its got 165,000 miles on it.

You've gotta tell us the secret to that one, because i'm in the boat like the other 'cats on here, i'm letting like 300 - 320 tops.

before i put my SRI in my 99 V6 i was getting 340 or so, and i thought i should have gotten more..... of late i've been averaging 21 miles in the city.

i was also wondering if i could do anything mechanically to fix my fuel effiency.

i don't have a lead foot either. so whats the deal?


be cool

 

[Da_nemesis]

is it because you guys have bigger tanks than my teg?? because i'm only getting 250 miles tops on full tank? i'm like wtf??

 

[Noot]

My tank holds 17 gallons. When I refill, I put in about 14-14.5. Over the winter, I've been getting 200-230 mpg. 230/14=16.4 mpg = bad.
Maybe I'm the only one, but I record miles and how much gas it takes to top her off in my car service journal every time I refuel. Ill have to look back to see what I usually get in the warm months.

My '98 v6 with 78k miles gets about 19 in the city and 27.5 mpg on the highway with the A/C on half of the time. Most of my driving is in the city but never in rush hour, I usually go around 270 miles per fillup. All I have is a K&N filter. The best I ever got was a 23.7mpg combined.

Where do you live? Could be due to weather changing.

 

[Noot]

I live at about 4800 feet. I know that altitude has a small affect on fuel economy.

 

[boostaholic]

did you get a tune up recently? if not.. do it.

did you get a tune up recently? if not.. do it.

I'll get that done when I get my timing belt done. Not gonna be cheap.

New forum member here, so if this suggestion sounds stupid forgive me. I had really bad mileage last summer, really, really bad!! I'm talking about 10 mpg. in the city and 16 highway. I had a new EGR Valve put in about four months ago and my mileage has been on the increase ever since. Used to get about 150 miles between fill ups (14-15 gallons) and now get between 325-350. Although my mileage still isn't as nice as some these members are posting I'm still elated that I'm around 23 instead of 15. Hope that this may shed some light. Also, when the dealership replaced the EGR valve they also cleaned the carbon in the surrounding areas.

i gets 400 miles per fill up...

 

[divinewisdom]

i am getting like 19-20 MPGs. i think its becuase my catalyic converter is gone.

 

[vietboi_2001]

i'm getting about 350-370 miles to the tank with mods posted on sig. it has about 64000 miles now. i think we all need a tune up, both o2 sensors changed, tranny fluid change, and clean out the intake manifold. when i first got mah car, it could do 420 miles. so yea, try these. and for all ppl who don't look at their J30A1s carefully, 98-00 uses spark plug wires, not the 01-02. 01-02 uses ignition coils over the spark plugs.

I was averaging about 250-270 (19-20mpg) miles to a refill, then recently I cleaned throttle body and drilled the EGR port, and replaced my O2 sensor, and now I'm getting 320-350 (22-25mpg) miles with a mix of city and highway driving. My Accord has 116K on it, and I have NEVER gotten fuel economy like that never ever since I had it. It's even got the orginal air filter! :eek

I really need to replace that.

Something you would might want to remember is that I believe the car was rated at 20mpg city and 28 highway. So depending on your driving habits, condition of the car, and whatever ... Your fuel mileage may be normal for the conditions you drive in.
