I have a 1990 gmc suburban, 112000 with a remanufactured motor from jasper with around 3000 miles on it. I have had no problems until I changed the oil with a k&n filter and 10w30 oil and now the oil pressure gauge stays at 60 while driving and even right after start up. I changed the oil again with 5w30 and a purolator filter and it still stays that way until I drive it for a while then only while idling will it go to as low as 30-40 but once I give it gas it shoots right up to 60 and sometimes it will go above 60 and that's maxing the gauge out, before it would stay around 30-50 and rarely go near 60. It does not run any different, should I be concerned or is this normal.
