#58 of 87 Re: Latest tank [rangner]

That's great if your next tank doesn't average less than 20. Did you use the same pump? Some fill more than others, due to air pockets and other factors.

No I didn't. I'll check at the next fill-up using the same pump--if I can remember which one.
But the needle pegged at the same place it always does...
I'll wait and see what it does on this tank.
#60 of 87 Re: Conversions for the non USA based [grahampeters]

There is a simple conversion between mpgUS and L/100km: divide whichever one you have into 235 to get the other. To convert between mpgUK and L/100km divide whichever one you have into 282.
1. 8.0 L/100 km ==> 235/8 = 29.4 mpgUS
2. 8.0 L/100 km ==> 282/8 = 35.3 mpgUK
3. 29.4 mpgUS ==> 235/29.4 = 8.0 L/100km
4. 18.8 mpgUK ==> 282/18.8 = 15.0 L/100km
#61 of 87 a change to mid-grade (89 octane)
Jan 21, 2007 (1:28 pm)
Not many posts going on here so I'll mention my change from 87 octane (almost always cheapest found) to 89 octane.
It apparently dropped from 27 MPG to 24 or 25 at first. Now after 3 tankfuls it's back again to 27.
I almost never buy gas from places like Chevron, Exxon, Shell, etc. so it's usually Murphy USA, RaceTrac (or Raceway), Pilot, Wavaho.
I remember when I tried Shell premium once (only once) and I think the MPG increased to 28. But that was a couple years ago so I can't say that with absolute certainty. I'm considering paying a little more for awhile and see if it helps stop the engine knock I've been plagued with.
For now I'm still getting the gas at the cheaper places and I might move on to the expensive stuff at least temporarily to find out what changes happen. I'd have done this sooner if not for the bad timing of price increases.
Interestingly, the car is rated at 21 city, 27 hwy. I probably only drive in city traffic 10% of the time so the gas mileage must be what's to be expected.
#62 of 87 3.0H6 vs 2.5T mileage
Feb 21, 2007 (3:10 pm)
do people think a 3.0 Bean will get better mileage than a 2.5 XT OB turbo with auto ? I ask because its probably a choice between those two to replace my 98 legacy (unless the bums at SOA come out with a 2.5i with VDC).

VDC will propagate down the scale and probability of getting it with 2.5i in 2008 is high, as Subaru wants to capitalize on IIHS top ratings. Perhaps Ltd. trim first - who knows.

It really depends. I think if you step into it, i.e. accelerate and really use that turbo, it'll use more gas. Plus it requires premium, while the H6 can make do on regular.
If you baby it, it'll probably be about the same mileage.
Odds are the H6 will cost less to fuel up, especially if you use regular or plus.
#65 of 87 2002 Impreza WRX Sedan 5MT - Gas mileage
Feb 28, 2007 (1:47 pm)
Hi, new to the forums. I don't see many WRX listings in this forum so I figured I'd chime in.
I've owned the car since it was new. Now has 73,400 on the odometer.
Local driving - lots of shifting, stop signs, traffic lights, etc. I will get about 20mpg.
Mixed driving - Some highway mixed in with the above I get in the 22-24mpg range.
Pure Highway - I sometimes take the car from NY to VA for business trips. I'll set cruise at 65mph (when possible). Last trip I was able to pull in 30mpg on the ride down. Basically I filled up the tank the night before in NY. Drove down to Reston, VA and gassed up. The ride home was a bit less. I calculated 28.5 mpg. There was some more traffic on I-95.
I have been running Mobil-1 synthetic so maybe that helped a bit. As for tires I'm running stock 16" rims with Falken ZE-512s.
Also my car has the turbo boost gauge on the steering column. I tend to use it to tell me how hard I am on the gas. I try and keep it out of the boost range as much as possible. Of course it is a WRX so I get on it once in a while. Very large grin on my face when I do that

Just passing 60K. It's a wagon. My commute numbers (3/4 60-70 mph 1/4 city or traffic jam) is consistent on 24 mpg.
My highway (interstate cruise 75-85 mph) - lucky to get 27, more reaslistic is 25-26 mpg.
City stop and go: 19-20 mpg.
Motor oil: synthetic. Tires: stock 16" with BF Goodrich Traction TA.

What does the pinging sound like?
