I changed my old gear oil and got a nearly 3 mpg boost in mileage. No change in driving style, just clean gear oil. I wonder what's going to happen when I get around to doing the transmission fluid?

That must have been some nasty gear oil.

Moderate gas pedal allowing the transmission to upshift quickly, otherwise realise it is an AWD car and will have good to rotten around town mpg depending on how many stop signs there are..... like here

Buy a Scangauge 2, set it to read instant MPG and velcro it to the dash where it's easy to see. Then use that to modify your driving style to maximize your fuel economy.

 

Or, install a vacuum gauge and keep the needle between 10" hg and 20" as much as you can.

I'm getting 25mpg in the city right now which is about as good as it gets for the 98 outbacck impreza. I was just wondering if there was anything that I could do besides personal adjustment.

 

Thanks for all the replys!
