Hmm Honda dealers buy their oil in huge barrels, so it's like $15 dollar worth of oil at most.
Get Honda dealer to quote you service with the Honda FEO ultra syn..... it's $70 extra or so (read: even if you are using your own oil, we'd still charge you for the Castrol Magnetic which we will not be using).
Honda wants you to see the dealer twice a year. Its like going to see the in-laws which you hate... twice a year.... only that the Honda dealer will cost you more.
