Gas Mileage 1998 s320

I have taken my first road trip from Florida to Atlanta Ga and to my surprise
I could not believe that such an old car gets 600 miles per tank of fuel.

Comfort , style & gas milage, what more can you ask for. My '96 has been the best car I ever owned. At just shy of 200K I don't do road trips anymore even though I have no reason not to other than not wanting to push my luck. Enjoy

I am getting 550 km/ tank in my s320 (60/40- City/Hwy). This is with new OEM plugs and air filter replaced less than a month ago. I use only 94 Octane from Petro Canada. Any suggestions?
