Hi folks!
I'm getting my 60K recommended service (big one!) today. It consists of mainly flushes. My question is after this service what kind of gas milage increase can I expect? Currently I get 14-16 mpg mostly in-city driving (only 9k per year) I use premium fuel religiously. Any other things (surprises) can I expect? Thanks in advance for any and all input!

With spark plugs (are you getting those done?) you will notice maybe a little, maybe more.....

With just flushes, dont expect ANY difference!!! What is actually getting done??

They should clean out the throttle body, exhaust syste, plugs, fluid check, check belts, etc with a 60k service.
