oil pressure light pulsating on and off - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's done it twice now in the past week. My oil pressure light on the dash will come on randomly, both times the truck is at full operating temperature....the light will pulsate or kinda flicker. The oil is full. I have a new oil pressure switch too already.

I'm running a fram filter. I know now that these are horrible filters after reading this site. I won't use fram anymore. I'm about to change the oil this weekend anyways. I'm going to use a Napa gold filter and 10w 40 valvoline.

Do you think the fram could be causing my issue?
