Today while idling at the post office I noticed my oil pressure gauge was all the way to left on the L. It would raise to normal once I was at cruising speed. For the 2 years Ive had the truck it has always read high.
I checked the dipstick and it said fine. So I went ahead and gave it an oil change with rotella 15-40 and an fl-1995.
When I first started it up with the fresh oil it slowly raised to normal, while still parked idling. Started driving and everything seemed fine. But then at the first stop it dropped all the way back down. The gauge reads 12 oclock normal while cruising.
A couple days ago I deleted my banks airbox and cdr for a big donaldson filter and road draft tube. Im not sure if this started happening at the same time.
Any clues? What to check? I know I should probably get a better gauge but what can I check know? Truck in my signature.
