Oil Light Came On

Agree that it is best to run with a gauge. I remember as a kid the Darts and Volares my parents had would occasionally filicker the oil light at idle. Last spring the Dart I bought the previous year had the oil light come on. Sender I thought, but the light stayed on off idle more than I liked. Cut the filter open to find all kinds of carbon light crud. Car sat for years before I got it, and the curd loosened up and blocked the filter. Glad I didn't blow it off as "normal" and added a gauge.

Also had a Durango that the gauge every few months would occasionally show zero at idle. No lifter tick, etc. It was a beater with a heater at that point, and oil changes weren't high on the priority list. Treated it to an oil change one day and realized months later I never had the problem again. No it wasn't a Fram filter, infact I think it was a Purlator. Pulled the engine when I sent it to the scrap yard the 300K on the clock.
