Default What kinda MPG are you NA guys getting?

My new OBS is getting only about 25mpg for road trips that are 90% highway. That is a far cry from the 28 MPG that is listed on the sticker.

I have about 2000 miles on it yet. Last road trip I averaged 60 -65 with the cruise control on (also known as anti-ticket mode). Got about 350 miles when the low fuel light turned on. I was expecting to get around 400. No hills to climb either - eastern shore, MD. Was keeping revs between 2 and 2.5 x 1000 rpm.

No mods. Not running AC, windows open maybe 50% of the time. I might try the grounding mod when the spring "really" hits and its not cold or drizzly out.

I'd prefer to skip the posts about "why you gettin' a scoob if your worried about mileage" and such. I'm not driving a Rex...

Part of the reason that I chose this car was that is was rated at 28mpg Highway, with all wheel drive. I'd like my car to realize that expectation.

Thanks in advance!

Zach

That is about what I get, depending on what gas station I go to. I have heard that the car is not fully broken in till about 8k miles and that is when you should start seeing it's true MPG. I have 17k on mine now and generally get anywhere from 24-26.

Oh, nice to see another green '04 OBS!

Heh, well the next big test will be the road trip to Quebec in July. I am going to try and get it grounded before that trip... 700 + miles one way. It surley nice up there though!

On highway trips I generally get 27-28mpg. I think the furthest I've gone on one tank was 380 miles and I put something like 13.8 in it.

highway i got 30 mpg with the ac on on a long trip last summer, usually i got 25-28 highway, 20-22 when i'm driving around town most of the tank

but keep in mind at least up north we still have the winterized gas which drops your mpg a little

Wait until late spring/summer and see what you mpg looks like. Our '02 OBS pulls about 28 mpg in the summer, more like 24-26 in the winter.

I'm not really worried: we get about 8-10 mpg while on stage.

Going up to tahoe yesterday, I got around 25. Kindda disappointing when you're use to a 37 mpg car.

On a 1200 mile trip up the I5 corridor last year with the wife, baby, and accompanying load, I got about 24 miles per gallon at 80-85 mph in 90 plus degree heat with the air on high.

I usually get about 20-22 miles in mixed driving, and I am 'on it' a lot .

My car has no power mods.

Windows open at highway speeds will actually lower your mileage over running AC, or so I've heard. I get 27 usually doing about 75% highway on my daily commute.
When I do 90% highway it's 28.5. Running AC for my daily commute, 26.5.

Default MY02 TS manual trans. wagon last tank 23.5 mpg

Probably still winter blend of gasoline here in MA.

Couple of tanks ago I got 25 mpg on a tankful of Sunoco 87 Octane with some Lucas Fuel Conditioner... I've been using Sunoco 87 ever since, and my last 2 tanks were 24 and 23.5 mpg.

About 300 miles a week, commute is 27 miles, half highway, half surface roads. And I give my car the old Italian tune-up every morning on the way to work (redline it in 3rd and 4th getting on the highway)

You might also find you'll get better MPG at higher RPM (3.5K) versus your stated 2K. Engines are more efficient the closer they are run to their torque peak. I found a measurable increase in MPG running closer to 75mph on my highway commute versus the previous 70mph.

2.5RS, MRT, intake, window and sunroof open - 30mpg average, 90% freeway.

I notice that the most effecient speed seems to be around 70-75mph. I've managed to get over 29mpg only once, and I've taken a good 10k in road trips in my car.

Default How'd you get such good mpg, Julian?

How much of a difference did the MRT (headers, right?) make to your mpg? I have a homebrew cold air intake myself, the grounding mod, 39 front/36 rear psi in my tires, and during the summer, the throttle body bypass (which isn't bypassed right now), and I've never gotten better than 27 mpg on a tank of gas... my holy grail is a repeatable 30mpg.

My next mod is synthetic manual transmission fluid (Redline)... I'm not too sure I'll be able to get headers, but if I could eek out a couple of mpg from it, it might be that much easier to justify to my wife, especially with increasing gas prices.

Better mileage in the winter???

I have always bee dissapointed in my city mileage. I get like 21 mpg with 60% in the city, if i'm lucky. I'm fortunate if i get 300 miles per tank.
If i'm just on the hwy i'll get like 27-28 mpg.

I think my cat is bad becasue i get a rotten egg/sulfury smell out of my exhuast.
