Hello again,

Much thanks for replies and help.
A bit confused on this.

Are you folks saying that the 5W 20 that Honda says to use Must be (all)
Synthetic only ?

Or is 5W 20 that is not synthetic, just the regular stuff, is O.K. ?

I read somewhere that they should not be mixed, so really confused.

Thanks again,
Bob
