What kind of oil should be used in the 6-cylinder Honda Odyssey?

Answer 1

For Hondas still under warranty, it's always best to follow the manufacturers warranty requirements. Actually, any oil you ever put in your engine should, at the very least, meet those standards. That said, I highly recommend 100% synthetic oil with one caveat: If your Honda engine has oil leaks it's a good idea to get the leaks fixed prior to switching to synthetic oil, since synthetic oil tends to clean up the crankcase removing sludge that may have previously plugged or slowed leaks. Of course, removing sludge is a good thing. I have run Mobile1, Red Line and AMSoil in my Hondas (all of the aforementioned exceed Manufacturers recommendations) and while I had good results with all of these synthetics, I have settled on AMSoil.
