Hey guys, the last three days, my oil light has been coming on, but only at idle. The first day it was just a fast consistent blink, almost looked like the light was shorting out. now last night it was on full. AGIAN, only when at idle, and the same in gear or not. I did check the level, even added half a quart just to make sure, with no change. only thing I noticed is that it seems to be more likely to do it after its running for a bit and warmed up. It is coming due for an oil change, but this has me baffled. any thoughts?
