2005 Baja Turbo 67,000 Miles

Mods: WR Intake, Hard Bed Cover. 215/70/16 oversize tires just put them on three weeks ago did not effect to much.

Every since i purchased the car 28,000 miles i've been averaging 16-17 Mpg's!

Car runs great no CEL

I think thats the lowest MPG of anybody with a turbo on the forum.
Even though i tanked up for less than 3 bucks a gallon for the first time in almost a year, i'm constantly worried about my MPG's

My friends with his F-150 almost gets better MPG's than me!!!!

i'm not sure of the possible reasons for such lows MPGs here are some idea's
1. midwest gas (high ethonel mix)
2. Bad turbo (to much lag)
3. I'm leaking fuel (not likely)
4. Needs to be re-tuned (i've reset ECU many times)

Miles Fill-up Price MPG
231.700,mi,15.553,gal,4.450,14.897,mpg,0

197.500,mi,14.210,gal,2.890,13.899,mpg,0

Thats about 60% city
40% highway

Here are some of my last number

If anyone has any feedback or ideas i would really appreciate it,
i've almost considered selling the car when gas was at its highest,
i would love to average about 20 mpgs mixes like some of the other guys.

In my experiences, it seems as though city driving really tanks your fuel economy. Probably due to it's excessive weight (3660 lbs turbo/auto) Even with 85% highway miles, I only get around 22mpg typically at best.

Imagine my surprise when I calculated 25.5 mpg last night tho - that was 100% highway miles, doing an average of 70mph.

I looked at a Forester last night. NA auto gets 27 highway/20 city.

Since my ECU has been cracked, I still need to look into custom tuning for an HHO solution. Put it on my list!

Latest trip was 26 mpg highway (DCA to SYR) right after an oil change. Michelin Primacy MXV4's at stock PSI (33 around). Normally we get about 20 mixed, 24 highway. Auto/turbo.

Don't know if you bought the car new or used but if you bought it used here is one [admittedly] WAG (wild-a$$ed-guess): The previous owner monkeyed with the ECU for whatever reason to the point where you are running Open Loop all the time. If you have a diag cable you can check it out with ROMRaider to see just how often you are in either open or closed loop. Even if you bought it new you can still check it out. This MAY account for the poor mileage.

sounds possible i did buy it used, sad to say i don't have a diag cable, i'll try to get my hands on one and check it out....maybe the previous owner did fudge around with it, at this point i'm looking at all and any possibilities.

I dropped of my Baja at a subie dealer when it had like 28,000 miles they kept the car for two days and told me that they found nothing wrong so there was nothing to fix. but that didn't change the fact that I'm getting crappy mpgs , but they didn't care and then I even contacted subie Corp. and they were no help either. recently I was thinking maybe the MAF sensor is faulty but not faulty enough to kick on the check engine light.

As of late, the best i've done on a 30-70 city highway mix is 24.2 mpg. the bed cover is helping, as is having the proper size tires on my damn truck :-).

Wow.. I've considered going through and lowering my boost map and then maybe making some small adjustment to my fuel injector pulse widths after that if necessary.. see what it does to my mileage. only problem is being able to switch my ECU maps on the fly. Perhaps make my map more contrasted - very light to no boost and then heavy boost if throttle is 75% or over (passing cars).

This would ultimately be exceptionally useful if I ever put together an HHO solution, tune the engine to run a lot leaner when it's burning hydrogen and to not throw stupid amounds of fuel in the cylinders to attempts to compensate the lean burn.

I was tuned by Germaine Riddick @ TurboXS in Gaithersburg Md. If you call down there he'll probably e-mail it to you and you can tweak it to your setup. I doubt we have the same mods lol.If he won't just pm me and I'll dig out the cable to pull it for you. Keep in mind... my best #s were verrrry painfull to achieve. No more than 5 over the limit and shifting no higher than 3500 for a whole tank of gas.

That is wayyy over my head. lol. I can only say how much I love my Utec Delta. I have the remote map selector (obviosly) and would never go back. YES there is a SLIGHT hiccup once in a while when the two ECUs switch off but it's barely noticable. That's why I went to TXS , Germaine makes the base maps that are available for download on their site so I figured if anyone could get it right it would be him.

03, NA, auto. 148,000 miles. Removed cross bars on roof rack. Tires at 38 psi. Mixed city/freeway at 27.7 mpg. City only 24-25 mpg. I haven't done any straight open road running, just the commute to work so I'm expecting 30 or so on long runs without traffic jams. And if I run the Baja the way it wants to be run I get about 25 mixed and 22 city! Now that gas is down to $1.58 a gallon I drive it a little harder than I did at $4.67 a gallon!

I'm running an 06 5-speed NA Baja - only 28k miles in the 2 1/2 years I've had her so far.

I've noted on all of our vehicles that the crap oxygenated fuel/E10 we get here near Philly hurts mileage.

So I didn't think much of it that for more than 2 years I only got about 22 mpg in mixed conditions, with a peak mileage of maybe 26 mpg on an occassional roadtrip.

At least I DIDN'T think anything of it until, on a whim, I removed the crossbars a couple of tankfuls ago. And BAMN EVERY SINGLE TANKFUL since then has shown a 3 mpg increase. Still mixed, mostly backroad not highway conditions - 25 mpg. I'm interested what a highway run for a full tank would show.

Just thought I'd mention that as something to consider for anyone who wants to see if they can get a few mpg more out of their Baja.

I think I tried removing my crossbars once and it didn't seem to affect my mileage. And I've got the sport lights mounted on mine.

It might be worth testing again - I tracked that mileage for about 26k miles before I removed mine and I've seen the increase on every tank since (about 1-2k miles now).

I have nothing to base my mileage on since I took my bars off within 5 minutes of getting home the day i bought the baja. I usually get 25ish with mine. i got up to almost 29 once but that was painfully slow highway driving.

you guys want painful: buy an SVX
