Is there anything like an engine tune-up for a 2007 Prius? My car has about 68000 miles on it but just curious if and when a tune-up would be necessary. Thanks, Jerry
There really isn't much to a tuneup: at 120K miles, the iridium spark plugs should be replaced. Consider replacing the PCV valve then as well. The engine air filter should be replaced at 30K mile intervals and the engine/inverter coolant should be replaced at 100K miles; then at 50K mile intervals subsequently.
