What kind of MPG should I be getting out of an M42 with an Auto, On regular I have averaged last 3 tanks 20.3, is this right? or should I be running premium. |  |  | | 09-26-2009, 04:53 AM | #2 | | Senior Member Join Date: Sep 2007 Location: asdfasdf Posts: 10,002 |
you're really supposed to run at least 89, IMO it's not that much more expensive so why not? I typically get around 25-30 with my standard M42 on 93, mostly city driving | | | | | 09-26-2009, 05:16 AM | #3 | | Senior Member Join Date: Jun 2007 Location: Safety Harbor, FL Posts: 112 |

Depends on how you drive and what, if any, mods. you have.
I have a Dinan Stage I chip, tend to have a pretty heavy foot around town, and probably average 18-20 MPG. On the other hand, I've gotten as good as 33 MPG on the freeway when I'm taking it easy. | | | | | 09-26-2009, 07:37 AM | #5 | | Senior Member Join Date: Apr 2008 Location: Austin Posts: 3,059 |
I usually get 16-18mpg on city driving. So it's actually normal. High way, I'm around 25-35mpg. __________________ Come get a ti-shirt

Thanks, I do mostly Highway driving but ocasionally sit in the parking lot on 1-5 on my way home from work, moving from parking spot to parking spot for about 4 miles untill the traffic clears.
This last tank I put in premium ($.26 more a gallon) but will try the mid grade next tank. | | | | | 09-26-2009, 07:54 PM | #7 | | Senior Member Join Date: Apr 2008 Location: Bethlehem, PA Posts: 1,106 |

If I don't I get worried. If I put in 4 gallons I should be getting 120 miles out of it. __________________

225k miles and still the Ti goes on | | | | | 09-27-2009, 11:32 PM | #9 | | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 |
Over the summer I did 90% highway driving and I saw at least 32mpg on the trip computer (reset every time I filled up). Now that I am back in school and my commute is about 5 miles per day (all city) the trip computer shows about 21-22mpg. That's with a 5spd M44. __________________ ~Dave~

I have a 95 with the M42 and 5 spd, It shows 24 on the computer consistently unless I do a long freeway run where 32 is about my average and I drive 65 to 75 depending on the limit... And I'm in the Portland area as well.

Hate to brag but I'm running a 2100cc M44 turbocharged and get 33-34 mpg on highway if I stay out of the turbo for the whole trip. City I get 26mpg off turbo and around 16mpg if I'm running hard.
This is due to surface flow tech on the valve surfaces that causes a tumbling effect. It increases milage | | | | | 09-28-2009, 06:29 AM | #12 | | Senior Member Join Date: Feb 2009 Location: Charlotte / Thomasville NC Posts: 240 |
Wow, I get at least 30mpg combined in my Ti with a manual.

You changed your plugs lately, it always make mine run better if I let them go over about 15K it starts to fall off..
If you have an auto service the tranny and use good fluid.
Make sure the brake calipers are all free, a little stick will hurt there.
