Add. To My Timing Belt Replacement Post....MPG Issue Question.....

[FlaAveo5]

I forgot to ask, in my post last night, about my finally getting my timing belt kit replaced. As anyone who has read my old posts knows, the MPG on my car since the day I bought it has sucked!! I NEVER get more than 19MPG, all city driving. The dealer couldn't fix it, at all, during my 3 yr warranty. All I ever got as an answer from them was,...'you don't drive it enough, so it is running rich.' Well I wanted to know. Is there ANY chance that having my timing belt and all the other parts replaced, with new, (even though it was new when I bought it, of course), could it have been 'set wrong' from the factory?? And the timing was off all these years, causing it to give me horrible mileage?

I was on totally empty before I had the kit put in, so I filled up yesterday, and my mileage was 16!! The lowest ever!! I won't know for weeks, if my mileage improves or not. But I wondered if the timing was off...that the ever so important 'variable valve timing', was not set right??

I can drive like a little old lady, or like a ricer, and I get 19mpg. But this 16mpg was a big shock yesterday. I filled it up from next to dry. I never do that usually, but I was getting this done, so I put off filling it up, till I had it done, just for this purpose...to see IF my MPG goes UP, after the repair. Is there any chance this will raise my mileage? Or is that not possible? Anyone know?

If it was set wrong from the factory, it would have been caught. The car will run horribly (ask me how I know haha), or not run at all.

So, unfortunately, I wouldn't look forward to better fuel economy.

Bummer. Was hoping I'd get 30+ mileage now. FINALLY! Getting the mileage that a new full size truck gets, in this tiny car, stinks! I traded in a 2004 3.0L Ranger that was getting 19mpg, when the first 'gas crisis' hit, and gas went to over $4 a gallon. I traded it in on the Aveo.
Thought I'd get 30++ in my city driving. Could have kept my Ranger Edge, and its Chrome Yellow paint color is now a 'collectors' color. VERY hard to get/find. And with the way i take care of my cars/trucks, it would have barely 50K miles on it now and worth a hell of a lot more. Oh well......

It runs great so far. I will give it a week of highway/city driving, to make sure it still runs as smooth as it is, before I leave this garage a positive review on Yelp. I like to do that for good work. I also leave BAD reviews for crappy work

Believe it or not, i am surprised...my mileage has gone UP by almost 4 mpg! I'll check it again on his next refill, but it went up to a huge 23.4mpg. For this car THAT is huge!

When was the last time you did a "tune up"?

Replace the spark plugs (make sure to gap them correctly), plug wires, air filter. Clean out the throttle body. Run some fuel injector cleaner through your gas tank. Seafoam the engine through the brake booster line. And take the lead out out your right shoe!

i do that yearly. I put in the new plugs, Bosch 4 point platinums, and replace the filters, etc, ....but nothing helps get more than 19mpg. And i WISH i had a lead foot. I have always driven like a 'little old lady'....and glide to stops, no jack rabbit starts...but now i am DRIVING it to see how it handles now!!!

can ANYONE read that post above??!!!!!

Thats great to hear. I'm glad I was wrong.

[FlaAveo5]

dont know if it is a fluke, or i cant add right, but tonight i have 99miles on the car, and it is at 1/4 of a tank used! i am in total shock. My luck the gage is broken

I hope your mileage has improved, it seems like it has. I only get about 31 MPG in my '04 Aveo, and it's all highway driving with little stop and go traffic. Mine is a 5 speed sedan, and I thought when I got it I would get better mileage also, but it just doesn't happen. I had a 3 cylinder Metro for several years and it honestly got about 42 MPG. Not to be nosy, but if you don't mind sharing, what is the approx. cost to have the timing belt replaced? Thank You. I have had mine done two times and I think I paid too much to have it done, but not sure since I don't personally know any other Aveo owners.
