I was just told that the dealer I've been going to is no longer the best place to have my Insight serviced. I need and oil change soon so I called another dealer that screwed up my wheel covers, in the past but is supposed to be under new service management. The original dealer charges $35 for a 0W-20 oil change. When I called the 2nd dealer they said it would be like $50. When I asked why the difference, I was told that Honda recommends synthetic oil for my car. They said the other dealer is probably using a mixed blend and they don't recommend it. I would like some feedback. The car's been doing fine so far. Does 0W-20 even come in a "mixed blend" version?
