I do not think it does. I top off exclusively, and the amount
of topping off required varies quite a bit due to the highly-
variable amount of
Fuel consumption will vary with driving conditions (wet roads use
more power, the water drags on the tires), cool damp weather gives
more hp from the water vapor in the air, AC use (climate control,
remember, it's automatic) can use a mpg or so, idling time, number of
hard acceleration

TIPS ON PUMPING GAS
I don't know what you are paying for gasoline but here in California we
are also paying higher, up to $3.50 per gallon. But my line of work is in
petroleum for about 31 years now, so here are some tricks to get more of
your money's worth for every

I'll try topping up the tank as you suggest, but I'm wondering how
much
extra fuel goes into the tank by topping off? A quart maybe?
That's true of the gasser SL's, certainly. But the diesels all
have a considerably greater amount that you can get into them,
and that amount varies quite a
My new Subaru gasser has a MPG indicator driven by the engine computer. It
indicates instantaneous MPG (which is useless because it jumps with every
twitch of the gas pedal) or average MPG since last reset. It consistently
reads about 1/2 to 1 MPG high based on manual calculations at each fillup.

I wondered about that. I watch the
Diesels suffer less from milage drop in city driving than gassers.
Not sure why, but I suspect it's because they use MUCH less fuel
idling (gas engines have to run WAY rich at idle to keep them
running) and gassers use more fuel on acceleration, too, I think. My

i found the computer in a Volvo i once owned to consistently lie about
what mileage we were getting; calculating manually always showed us to
be receiving worse than what was reported.

Bob,
It's real close on my CDI when I do a manual calculation vs. what the
readout says.

And the more fuel that goes in means that less mpg's were achieved -
On one side of the short fill-up. But the next one may get
erroneously _high_ marks. That's why I top off, for consistency
of the mileage calculations. It doesn't affect the true mileage
you get at all, just the 'jitter' in
resetting the trip meter every time?
letting the pump run slow until the nozzle shots off the first time and
not topping it off?
dividing the gallons pumped into the mileage indicated on the trip meter?
if yes to all, then i won't guess what might be causing such a
variance,...
cheers!

There may be a fault in the fuel injection system, we haven't had a
discussion of the ALDA for a while.

Hi Ya'll -
I check my mpg's everytime I fill up. For some reason it changes even
though my wife's driving is consistant - she drives to and from work each
day, no AC needed, no hard acceleration needed, stuff like that - and yet
her mpg;s will be 32mpgs one time and 28.5 the next. We fill
How often do you check tire pressure? Is it just after a tire inflation
when the mileage goes up? Perhaps, it's merely the change in wind
directionn.

With my diesels, I fill the damn tank till it fills up to the top of the
filler neck. Takes a while to let the foam settle.

My wife doesn't fill the tank as full as I do. So that skews things
a bit if I calculate based on one of her prior fillups, or vice-versa.
