Gas prices here in the US are starting to float upward too--it's
currently at around US$2.30/gal. for regular unleaded in my neck of
the woods.
On a somewhat related note, it appears the fuel gauge in my car
is malfunctioning. The needle is stuck in the "full" position as
hasn't moved in over 100 miles of driving. I tried pulling and
resetting the fuse for the fuel level sensor, but to no avail.
Looks like a trip to the mechanic is in the
cards... 
I think it's over margin issue.
piangz... it's like those older SBS buses, faulty fuel guage.. but
for e buses it's ok, they refuel diesel every night
