agree with betty. If you are going to be in the store for more than 30 seconds, shut it off. Any most important of all, some 14 year old can hop into the driver seat and drive away. I cannot suppose tyou do THAT many trips into a store without having to be in it for less than 2 min. Not sure what you have in your car, but i used to keep my car running when i used to bump music in a parking lot with all my friends after i got off work. We would just hang out there for a little since we really had no where to go. That killed A LOT of gas, but i did'nt care cause gas back then was like $1.23 for super. you gave the guy a $20 and do a fill up and you'd get change back. I can understand the logic behind the o/d thing. But i personally think that you might burn the gas you've saved by going 45 mph without o/d on if you're cruising down the local road for like 5 min. Either way, in local driving, i get about 160-170 on a half tank, highway driving is around 200-220.

But again, are you using good gas? Do you fil up at BP a lot? BP here on the east coast is a killer for gas mileage. I would fill up with BP gas and only get around 14-16 miles a gallon. It seems that they put a lot of ethynol in the gas...
