[QUOTE="Fred W, post: 1363929, member: 3828"] Your engine was very hot, so your oil was as thin as it gets. All oil gets thinner as the temperature increases. Thinner oil will return back to the sump by gravity faster than cold thick oil. Seeing or not seeing oil in the sight glass when the engine is running doesn't mean anything significant. As for the old style longer oil filters, yes they are still out there, but since they haven't produced them in years the supply is dwindling fast. Boats.net (aka Partzilla.com) claims to still have them in stock [URL="https://www.boats.net/parts/detail/yamaha/Y-5JW-13440-00-00.html"]here.[/URL] If you are insistent on running $12 OE oil filters I'd recommend stocking up as they will disappear soon. I prefer to run a good quality auto filter (Purolator) with the same or better specs for about half the price, and I can pick up locally with no shipping. Of course as with all things oil related, YMMV. [/QUOTE]
