Hi Doug,
Do you still keep a detail log book of your fuel stops and expense?

I get that kind of mileage drop when I have to use an alcohol mix in the
gas.

Not a real detailed log, unless I'm driving on buisness. I use
excel to keep track of milage and maintenance.

Thanks for the input folks, here is some more info. Yes my area does
switch to a 'winter' blend but not for another month or so. No I do
not use an alcohol blend of fuel ( E85 is just WRONG!! ). The brand
and grade of fuel are the same. I calculate my MPG manually and
compare that figure with the on-board smarts, the difference is less
than 0.1 MPG so that doesn't account for an 8 MPG drop .

The engine temp when hot is 140 C or about 195 F, I wouldn't think
that this is too cold but I could be wrong. It is at temp after 4 or 5
minutes.

The only other thing I did was to change the plugs, the NGKs I took
out appeared to be running OKish ( #6 seemed a bit rich) but the gap
was over .060 ! . I have checked all electrical plugs and connectors
just in case I accidentally disconnected something but all were OK.
