| Re: Gas Mileage...
It may be normal. Keep an eye on things like the oil level and the tire pressures. As temperatures drop, so do tire pressures. Low tires increase the cars "rolling resistance" and low oil (which is not uncommon for a N*) causes increased friction and higher temps in the engine which rob it of efficient power production.
Also don't forget that in the winter time most people have a tendency to warm their cars up. This burns fuel at a nice rate of 0 mpg, which will quickly drop your average. Be prepared to see lower numbers in town because of extended idling also.
There was another thread, the one about acetone in a N*, I posted a recent TSB from GM on tips for better gas mileage. If you can't find it let me know and I'll post it again.
