I was unable to find the regular Quicksilver oil I use on my 1987 Prostar 190 this morning & got Moble 1 15W50 & put it in the engine before reading an old container of Quicksilver that is 25W40. Is 15W50 safe or do I need to change my oil again?:(

I'm not an engine expert, but I'd have no problem running the Mobil 1 until the next oil change in my boat, despite the difference in viscosity.

Run it and have a good time, IMHO. No worries.

Just tell us how many hours you put on that engine in the last 3 years...:rolleyes:
Get the cash out of under your mattress and buy a new boat!!!
