Are you asking about coasting in N with the engine running? That's OK. Engine off is the issue for most automatics (they aren't properly lubricated unless the engine is on).

You're also going to want to look into aerodynamic modifications since you spend so much time on the highway. The low hanging ones are things like smooth wheel covers, partial grille block, etc. Check the mods list at the top of the page.

Also do you have a resettable fuel economy display in the Camry? I think yours does.

And .. welcome to the forum!
