I'm not sure about Honda...but the VW's and Audis I work on...if the owner wants synthetic..he has to start using it before the engine is broken in, or it leaks EVERYWHERE. I thought of going to synthetic myself...but not if my engine will start leaking.
I believe it only really matters when you switch to synthetic when a cars has a lot mileage like 150K+. I use full synthetic in the H22 with no problems and I assume synthetic was not used in it.
