30's.... highway or city?
I found I was nowhere near 30mpg city, even in my old N/A, but on the highway it should top 30mpg.
I just drove my 951 from Calgary to Vernon. it's a 680km drive with speed limits varied from 80 to 110km/h. I didn't drive with a light foot either. Tons of WOT and passing. All of that considered I also got a record 34mpg

I actually filled it until fuel spilled from the filler neck because I didn't believe it.
