Exact mileage calculations for your aveo? Here's mine.

I always had an idea of how much gas it was using but never really bothered to actually crunch the numbers and find out the exact MPG or L/100km.

So last time I filled up, I reset the odometer and did 504km then filled up again. It turns out that I used almost exactly 40L of gas to travel those 504km. So if I am not mistaken, this translates to 7.9L/100KM or 29MPG.

Usually I start the car and it's only moments before I start going, I don't wait very long. I'm not sure if this is bad for the mileage. On this tank of gas, I was definitely driving too fast, accelerating too fast etc but not the whole time. There was a significant portion of that driving which was between 90-110kph and quite a lot of city driving.

When filling up before having done the calculations, I felt the mileage was not very good. Turns out it's better than I expected given that I didn't granny it the whole time.

How about you? Real numbers of liters/gallons used versus km/miles traveled only please.

Sorry for the necro, was wondering what mileage people are getting nowadays. Personally I've kept a spreadsheet since a month or two of owning the car, and it's interesting to see how much it varies with the type of driving being done (2012 Aveo5 T250 1.6 5-speed manual hatchback). Also interesting is our fuel price, which is steadily creeping up...
My current average is 7.23 L/100km (39.09MPG UK gallons, 32.53MPG US). Some months have been almost exclusively highway driving interspersed by very short distances when I was at University, followed by lots of highway driving with the car full of household items, and in recent weeks it's been with mostly city driving with the occasional longer trip.

I've attached the spreadsheet so far. I've tried to keep it as accurate as possible with recording the odo reading at every complete fill up, skipping the 1.5 months the car was undergoing warranty work and a few places where I filled up with less than a full tank. I'm quite disciplined with my driving, almost always shifting before 3000rpm and usually close to 2000rpm unless a fast pull off is required, and generally don't exceed 120km/h (speed limit on the highways ). Sorry to the US guys, it's all metric...

Points for the attached spreadsheet after it's science


Oh you hurt our feelings here in the US. You use a spreadsheet and don't even bother with a MPG column. /SNARK

My gas mileage was going down and after I got my head fixed (other reasons) I was able to get my MPG back up. It's running about the same numbers as you at Avg 32 MPG.

Precisely, I am a science student after all Glad to hear others are getting similar numbers.

I've been wondering about the "reserve" fuel, i.e. how much further I can go after the fuel light goes on. I haven't yet reached that state but I have filled the car with just under 40l, meaning there was just north of 5l left, and I assume that light goes on at 5l remaining.

In my car it's about a gallon remaining about 3.7 liters. So I suspect it's going to show lower for you than 5 liters.

Ah, OK, I'll keep that in mind. Thanks!

260-280 miles, 25-28mpg. Driving about 63mph (30mph with as little as possible stops in city) 90% highway according to my gauge which I feel is accurate as all 3 cars I've tested on WA/OR meters are exactly 3mph slower than my gauges. 2003 Jag, 1990 Cressida and the 2005 Aveo hb.

2.69gal, $24.5 for 9 gallons which fills it on Fred Myers auto off detect level, I try to always fill it at the last notch because of how far I have to drive I can't dip lower and it's cheaper at work than near home. Tire pressure 49front 44rear, correct pressure to the temps outside and tire sidewall rating. All season tires. I also try to eliminate making an extra stop for gas by filling only when I need to.

I think a street summer pattern would get even better mileage I also think all the wheel bearings need to be done. Needs the inner fender wells and maybe the GM roof racks removed since I'm not using them. No check engine lights.

I'll do some even more precise calculations soon although I'm always going to use Fred Myers auto off pump feature because self service isn't allowed and it's that much cheaper on the OR side.
