My latest tank was 36 mpg (30mpUSg), so I guess it wasn't a fluke: 75% top
up(highway). It's been warm and she's leaned out. Best I've got in the
past is about 28mpg.
Unfortunately, I can't afford to insure 2 cars, so the mgb must make way
for my offroad research vehicle (a 4wd subaru) for about 2.5 weeks of
fieldwork. Bummer. I'm glad I have an understanding insurance company.
Ususally lets me change my insurance back and forth between vehicles. No
