Thanks. This is great information. I didn't even think about changing the oil and transmission fluid to improve gas mileage. Makes sense though. We have a Sable that calls for 5W-20 oil. I didn't even realize there was a 5w-20 until we go the car. It says to run it year round.

As soon as it warms up some, I'll change the transmission fluid, oil and will do a few of these suggestions.
