Nope. The numbers I quoted are close to "best-case" scenarios. I live
in Calgary, 300km from Edmonton, which my wife and I visit about six
times a year. In summer, with all-season radials, cruise control and
without significant headwinds or crosswinds, I can get there on
one-third of a 60 litre tank, which gives me a fuel efficiency of 6.7
litres/100km, or (expressed as the reciprocal) about 15km/litre.
Multiply by 4.55 (to express it as km/Imperial gallon) and you get 68.25
km. Convert to Imperial distance, and 68.25km is 42.41 miles, per
*Imperial* gallon. If you convert to U.S. gallon, it's a conversion
factor of 3.79/4.55, or 0.83 approx. 42.41 x 0.83 gives 35.3, or
rounding, 35 miles to the *U.S.* gallon.
All of the above numbers get worse if it's winter: transmission
lubrication becomes thicker, joints are colder, winter tires have more
rolling friction, the engine has to work harder. They also worsen if
any of the initially-described variables aren't there -- if I'm in heavy
traffic on the #2, I can't use cruise control. Bye-bye fuel economy,
hello half a tank (30 litres instead of 20) for the same drive. And a
significant headwind can wreck your fuel economy, too.
Driving technique and proper maintenance/setup can make a big difference
in how much fuel you burn. So can the typical environment the car's
operating in. I can get almost 900km out of the car in summer on the
highway if the stars are aligned. In winter with mostly city driving, I
get around half that.
