Have a 2003 Dodge PU w/ 4.7 that does not see much use lately. In a moment of weakness I had the oil changed at Walmart on 9-26-05 with mileage of 54921. PZ 5/30 with the orange can of death filter. Noticed while driving this week that each startup the oil pressure gauge would creep from the bottom to the normal range. My mind immediately thought of the orange FRAM under the hood. Got totally paranoid. Had the oil changed at a different location today, 2-7-06 with mileage of 55856. PZ 5/30 with the yellow PZ filter. Now the oil pressure gauge jumps up almost instantly to the normal range. Again no science involved, just an observation. I hope that I didn't hurt my engine with the orange can.
