I have a 92 rado g60 I change the oil I used 5w30 and I put in a new filter could it be a bad press switch

Sorry about the lack of a reply on this, for some reason vortex didn't' give me your message till now.

Could be a few things, depending on what car you have. Could be as simple as old oil or an old filter. If it is a bigger problem, which flashing light could indicate, you might have an oil pump going bad

Flashing oil per light how can I fix the prob
