I've used Mobil 1 synthetic in all my Honda engines, both I4 and V6,
after a 10K mile break-in period. Synthetic oil works well for folks
who drive lots of miles/year or who live where there are extremes of
hot or cold temperatures. If you drive in a dusty environment or use

conditions. Right now I have Mobil-1 in the Accord and Havoline
Synthetic in our Acura TSX. You can also feel more comfortable going
the full recommended oil change interval with the extra margin a
synthetic provides. Just don't waste your money on a high quality oil
*and* then do the traditional 3,000 mile/3 month thing!
