has anyone come up with how to increase fuel economy, i am from michigan and as soon as the weather changed i dropped from an average of 17 to 14 obviously cold weather has an impact, i recently read an article about changing thermostats in full size gm suvs but i am being told you can't find a different degree thermostat that fits? or is there any other suggestions

thanks bevans

I'm not sure there's much you can do about the drop in winter. I see the same thing here, although it's more with my Mazda than with the Outlook. The Mazda averages 29-32 in the summer and that drops to 26-28 in the winter. With only 7.5 months of Outlook ownership, I don't have a real feel for the pattern. Besides, a good amount of my highway driving in the summer is towing, so that drops my summer average. :(

wait- you want to change thermostat to a LOWER temp?

If so- youre going to get even worse MPG?

These engines need to run at 210.
If its not around 210- the computer thinks the engine is running cold and will run as if the engine is cold (cold morning start)...

If you want to add a hotted thermostat... id like to read this article
