Many of the mpg 'records' of the past were set at 50 mph.And above that speed,mpg fell precipitously.
If you could run at around the old double-nickel speed,I think you'd have a strong shot at 100.
Fully warmed up,on a warm,calm,dry day,on as level a route as you could find,running at as constant speed as possible would be requisite for a chance.
Mobil Economy Challenge winners would allow speed to fall on climbs,and a little over-speed on descents.But steady speed on flatland.
100 mpg at 50 mph would be nothing to be embarrassed about.
Other motorists will hate your speed and share the one-finger salute as you impede their journey.Gotta love 'em!
I'll be rooting for you.
I cringe every day I commute in the truck,knowing that this could be the day when' Barbie' or' Ken' creamed 8-years of my work.
Sorry to hear about the traffic 'Kiss.'
I've learned to keep my lug nuts tight but I have no control over the 'other guy.'
