From the ever-popular diesel vs. hybrid topic to ideas for future hybrids, the forums section offers something for everyone. It’s not just about driving, either. Some owners are finding work-arounds for problems with MP3 files, while others are astounded by the sudden availability of Prius hybrids on Toyota lots.

Here are a few more topics you’ll find:

Some questions, but mostly great answers: How to know when to get the oil changed (listen to the dealership service department only if it agrees with the manual), what kind of oil to use, and how to reset the maintenance minder button on 2006 and 2007 model year Honda Civic Hybrids are all covered here.
