13 MPG/??? - Page 2

It's not just the blend.
The engine gives MUCH better economy when warm. Breathing cold air
into a cold engine makes for poor efficiency. Turning a cold tranny
and differential also makes for poor economy - and cold stiff tires
likely don't do a whole lot of good either - particularly when running
through slop and snow on the roads.

I noticed the same thing with my car. The mileage decreases were
larger than one would expect.

I would think cold tires would get higher fuel economy - less flexing
of the tires. However, in cold weather, I get about 10% less fuel
economy.

Jeff

Both increases and decreases are larger than expected, and only
because we have not had this instantaneous mileage info in the past.
It sure makes you want to modify your driving patterns, and in hilly
country pick it up a bit on the downhill (low-cost acceleration) and
geatly drop off the speed uphill, if this kind of yoyo pattern is
possible in your terrain.
