3.0L- 17 city/26Hwy/20 combined
4.2 L- 16 city/24Hwy/19 combined
4.2R- 15 city/22Hwy/17 combined
Generally a smaller displacement engine will produce better fuel economy than a larger engine in the same vehicle body as long as the engine is not grossly underpowered, which for the S-type, it is not. Speaking personnally my 2000 3.0L SE model has a lifetime fuel economy average of over 28 mpg over 104K miles . On long trips I have a best tankfill of 36.6 mpg and many 30mpg+ tankfills. S-Type are very efficient for their size and weight if driven correctly.
Driving style, tire pressures, and vehicle condition are important factors for achieving good fuel economy.

EPA numbers are of very little value in the real world- but that's another topic.

You guys are making me jealous with your 20's mpg results. I'm in Atlanta and do 100% surface street driving (no highway in my commute at all). My average speed is 17 mph and my fuel economy is at 13.6 right now. The really depressing part is when I have enough road I'm usually driving 45-55 so I'm spending ALOT of time sitting. It takes me about 45 minutes to complete a 10 mile commute.
