Hi Olds Folks, new member here. I purchased a 2001 Aurora two years ago that has an odd problem.I live near Lake Erie and the fuel milage difference between warm and cold temps is terrible, warm weather 20+, cold weather 12 avg. Engine with in specs. syn oil 5-30w, new air filter,maintenance by the book and tires air pressure maintained. I can see losing a couple of mpg due to winter formula for gas and other winter climate factors, but 10 miles avg per gallon. I live in a small town so not much stop and go, hills not problem. Anyone else living under these climate conditions having this problem? thanks and God Bless.
