Whats Your MPG

Postby Awesome-Trac » Sat Feb 22, 2014 5:24 am

I guess i'm kind of curious what everyone else is getting especially how gas prices seem to be going up. I daily drive my Trac pretty much everyday now "pain in the ass sometimes" but i'm averaging 15mpg city and about 23mpg highway on a 1st Gen motor/2nd Gen trans St165 since i finally got my speedo working. Hopefully i'm in mid range of decent gas consumption on this car :shrug:
So for all the Trac members Whats your MPG look like?

yo be honest I don't know what I am getting for highway or street. But overall I am usually averaging 19.5 MPG. That's city and highway.

My best around town with a 205 swap and RC box is about 19. I usually see closer to 17. I really want to see if I can improve it. At the track it drinks it rather quickly.

I'm trying to keep up with all my gas receipts for a whole year and get an average for both city/highway driving and warm/cold months. I have a few more months of data to collect and I'll have most of the info I need.

So far in these winter months with it being as cold as it's been my MPGs around town are pretty bad, roughly 13 to 15 and highway around 20 to 23 at most. I am hoping that doing an average for year-round MPGs would better reflect what my car gets on average, not separating whether it's highway/city or winter/summer.

May seem a little OCD but I guess I can be sometimes :)

Thinking about it just now. . my MPG may actually be better than I think because I forgot to take into consideration that my overall tire size is off from factory. My speedo reads slower than I'm actually going so I am really putting more miles on the car than what the odometer reads. . :shrug:

Yeah, you got to do the math on the tire size when doing it. I keep a log of the the difference which is 6.7% based on my tire size.

You can use http://www.miata.net/garage/tirecalc.html or 1010tire to figure out the difference.

Somewhere around 16l/100km when driving carefully, which is something like 15MPG. That's with a broken O2 sensor though.

My gen 3 has full turbo back exhaust, intake and boost controller. I have read claims that an ems can net better mpg when tuned right. I want to find a balance of power and mpg. If I am going to do a track day or run mountain roads, I don't want to have to fill up a few times due to an inefficient setup.
