thats like what... 40mph? thatll waste more gas IMO. ive tested this theory
on my daewoo(2000 lanos S) and my CRX (87 HF). running the engine in 5th at
speeds that low puts more stress on the engine (it must work that much
harder to accellerate in 5th as opposed to 4th or 3rd), thus resulting in
more fuel wasted. i usually shift into 2nd at about 20, 3rd at about 40, and
4th at about 60. 5th comes at about 65 or so, depending on my mood... this
is in MPH btw. in both my cars, ive made the trip to san antonio (about 90
miles from austin) with only 1/8th of the tank gone (gettin about 50mpg on
the highway in both cars.. more in the daewoo at times). i make this trip
weekly and have been doing so for quite some time, so ive had plenty of time
to run many theory tests. HTH!

How much more fuel economy do you see by this infintesimal change, in
comparision to a 90 mile highway trip?

Re: fuel economy
It should increase your mileage, so long as when you shift to a higher gear
you are not opening the throttle more than you were in the lower gear in
order to maintain the same speed. Also, avoid lugging the engine, as this
will put tons of stress on your bearings and significantly decrease the life
of the engine if done frequently. These torqueless wonders need to be
shifted at a reasonably high RPM in order to not lug them (unless you are
accelerating at a crawl... which is how you'll get the best mileage,
actually). That is the nature of an engine with no torque to speak of.

Very true, if you drive a roller bearing Porsche from the 50's.
