I took the 90 sov for a 393 mile trip yesterday. Figure about 5 1/2 to 6 hours driving. Elevations from 235ft above sea level to 1600 feet. After the trip I ran some numbers. My avg speed was 53.4mph. I averaged 22.1mpg, I even had the climate on auto set at 70 for the entire trip. Thats pretty good for a 21 year old car with a 147k on the ticker. I got it up to 90 for a minute or 2 within the trip as well. I used the kick down feature for the first time. That blew out quite a bit of grayish smoke
The worst part? About $69 for gas

Hows your mpg?

 

Pretty much on a par with yours, but figure around $160 or more, for fuel for the same trip.

And you guys think you have it tough
