Dang, I’m sorry to hear about this, but I was always told to have one of these:
not saying that you didn’t have one but many of us don’t have one, because you think the OEM one is just fine.
I blew quite a few engines and I can say that the OEM light doesn’t come on until your engine’s blown. just food for thought, so if your looking for that oil light, it’s not going to come on until you’ve damaged something internally. just my .02 . get one, there cheaper than another engine rebuild.
