Question about 2004 Toyota Prius
Took my Prius in for a 5,000 mile service. They also replaced the engine air filter and the cabin air filter. Before service I got 49 MPG and now I get around 42 MPG (with effort). I drive the same 100 miles roundtrip to and from work every day and nothing has changed. The dealer just says that 42MPG is darned good mileage. I have also noticed that there are fewer little car symbols on my energy recovery screen.
What was the weight of the oil that was put into the engine when it was changed? Prius engines are VERY PICKY about the proper weight of the engine oil. Trust me. I see this quite often. The wrong weight oil can do bizzare things, and def lower your mileage. Something you can check: Take off the tube leading to the throttle body, and look down into the intake. Do you see any oil laying in the intake manifold? If so, you DEF have the wrong weight oil. This will NOT set a Check Engine light, either. Hope this helps.

Why would they change the cabin air filter? I think that it only calls for a check at 30,000 miles/
