Default GAs mileage for N/A Baja's?

I'm only getting like 23 MPG combined city/highway for my 2003 auto trans Baja.

What kind of mileage do the rest of you get?

70% of my driving is highway at around 70 MPH. I would have hoped for a little better than 23. I think I'll put some new plugs and wires on it and see if that helps.

In the dead of winter I get 22 - 23 mpg. Lately I have been getting around 26 mpg, last tank just shy of 29 (that was mostly highway, but with windy cold weather). Best tank just shy of 31 mpg.

I keep a spreadsheet on my fuel mileage and the lifetime has been 25 mpg over 26,000 miles. That includes long, harsh winters.

I live in a rural area and I slowed my speed on the interstate from 70 mph to 60 mph and picked up around 2 mpg. It takes 2 minutes longer on my work commute, but I save a couple bucks a week.

Is your highway drive include a lot of hills where your Baja downshifts? This would have an impact on your mileage. Also, check your tire pressure and maybe even your front end alignment, although these shouldn't impact mileage that drastically.

OR ..... pull in the parachute..... I saw your user name is 10.5sec1992AWDtalon, apparently you spend some time at the track.

LOL...yeah I have the Talon as a race only vehicle and a 2001 SS Camaro too. The Baja is my new daily driver.

I think the 70 MPH or so is what's killing me. I'll have to slow down to like 60-65 on the next tank and see what happens. I gotta quit redlining it too I think.

Thanks for all the replys folks.

My 03 is getting 25.8 right now. Thats city/hiway driving back and forth to work. Worst in the cold of winter, with snow and remote start runnin for about 15 min was 21. Best of 31.1 on a trip back from the UP of Michigan last summer. I put plugs in mine at 30,000 but it made no difference in the mileage. But if you have never had plugs, thats a good starting place. I also try to keep my foot off of the floorboard most the time, so I'm sure that helps a bit.

I get between 25 and 26 combined.

When I slow down, mileage goes up. My best highway was about 29 I think.

Everyone needs to slow down some. What I love is the fact that everyone out there weaving through traffic, no signals and blowing by me on the RIGHT! are still sitting at the next intersection when I get there a few seconds later.

Is it just me or have driving skills reached an all time low?

I get around 250 miles to an almost full tank Gotta pay to play/drive. Then again I live in the boonies. Stop and go driving kills gas mileage.


EDIT: after driving with the rpm's below 3,500 most of the time I got 320 miles on one tank

I just did a couple 6+ hour trips to TN from Raleigh, NC, in my GF's 2003 NA manual Baja. 26.x on the way up there, 28.8 on the way back. (400.0, yes, point zero! miles on one tank!) Everything was a fairly constant 75 or up to about 80 when the speed limit was 70.

Cheers,
Anders

Turbo or NA?

We just took the cross bars off rallygirl's Baja, and it's noticeably more quiet. I'm curious what kind of gas mileage effect it might have.

maybe you need to drive it harder.

check your tire pressures too.

our 2003 Baja gets 350-400 out of a tank so 26-29 mpg.

If I recall my mileage increased after a few months of breaking in the motor. It should improve for you after a little bit of time.

I am hoping that further breakin helps. I have also noticed the idle is just so slightly off when not warm , just so litlle but might be sympton. I have an appt w/the SOA rep coming up for slighly out of balance tire feeling, window making noise when lowering and a whistle that sounds like it coming from the windshield at 60 -70 mph. I will mention this and get told "normal" I am sure

We just had this fixed. They replaced some of the stuff (sorry, exact "stuff" unknown") to do with where the side mirror connects to the door and it made a huge difference. The guy said that that's usually what the problem is.

Thanks for the link. I was bored today, so I did the intake. But, I used 2 inch pipe, at least for now. I understand that the 2 inch pvc has a slighthly smaller ID than the stock intake, but I figure it should more than compensate with better flow.

Using three inch you still need to choke it down to get it in the airbox, but I guess that would save using a street 45 as I did, so a bit more air.

One other thing I added. I sheathed the entire thing in a piece of flexible aluminum duct. The air space around the PVC should be a good insulator and the aluminum a good heat shield. Looks cool too (Like all the plumbing in the movie "Brazil")

Anyone know if you can buy 2.5 inch PE tubing? That would be perfect for this application - flexible, black, and easy to cut.

Poly Ethylene? Not sure. And I PM'd you pgv. Let us know the results of your test with the intake. Brian
