#19 of 28 MPG Issue.
Aug 05, 2010 (12:57 pm)
Mine isn't as bad as some of yours, but I've checked my MPG several times by calculating at fill-up. I always get numbers between 17-19 MPG. I drive mostly in the "city", though not stop and go traffic. The air conditioning is on about 80% of the time right now. Are these the numbers I should expect?

Well, it's winter time, so no air conditioning, and I'm still getting only 17-18 miles per gallon. What's wrong with my car?

As a general rule, identical styles of driving will yield worse mileage in the winter (even without air conditioning) than they will in the summer (even with air conditioning). Why? Two reasons:
1) Winter blends of gasoline do not contain as much potential energy as do summer blends, and
2) when the OAT is below roughly 40°F, fuel does not atomize as well as it does above that point; the lower the efficiency of atomization, the lower the fuel economy.

I've been getting considerably worse with winter gas. This car seems affected more than other cars I've had. I eventually got to where I was netting a bit over 26mpg with highway/rural driving. Since the switch to the lovely NJ winter formulation, I've been getting 24. Ugh.

Only in my dreams do I get 24 to 26 mpg. I calculate everytime I fill up, and I think the best I ever got was just under 24mpg, and that was only a couple of times. I'm tired of only getting 17mpg. I can't figure out why I go through so much oil either, but the dealer gave me some explanation that didn't make sense after I thought about it.

what kind of oil consumption are you talking about? What year and how many miles? Have you fixed the PCV issue? Do you see oil on your filler cap whenever you open the hood?
Many of these do use some oil, but it shouldn't be THAT bad. Mine was doing it when I first got it, but after upgrading the PCV system and using Castrol Syntec on my last oil change, it hasn't lost any.

2007 with about 32,500 miles on it. I've never seen any oil around the cap. I got the car used with about 26,500 miles on it. Had my 30,000 maintenance. Averaging a quart of oil about every 1500-2000 miles. I did have to add a quart just a few hundred miles after the dealer oil change at 30,000. Maybe that's not excessive, but more than any other car I've owned.

Rarely accelerate hard, rarely brake, averaging 34.5 via "consumption 2" on the display. During winter months was averaging 32.5. Just hit 20K miles. Commute 40 mi each direction.
#27 of 28 Still Burning Through Gas and Oil.
Apr 01, 2011 (7:30 am)
I just filled up again today and caculated at 17.8 MPG. Oh, I forgot to check the oil. I better do that. It's probably time for another quart since I haven't added a quart in almost 1500 miles.
#28 of 28 27-28 mpg in the Seattle area, 2008 GTI manual

We have hills, lots of them, stop and go traffic and 10% ethanol in the gas.
Much better than my 2007 Mazda speed 3 (21-23mpg)
Surprisingly, similar to my 2002 Honda civic SI 2.0 NA motor which had less power and torque and was lighter.
