I just changed the
oil in my Cobra and gained about 10 pounds of
oil pressure. All I did was change from a Fram
oil filter to a K&N oil filter. I used the same 20-50 Valvoline Racing oil that I have used since 1976. I used to have about 50-55 pounds pressure after an oil change and now I have 65 pounds. Is there something different about the K&N filter that would cause this.The oil is flowing as the filter got warm and I also checked the level and it had gone down just a little from filling the filter. It is getting late so I never drove the car far but the temperature did get up to around the normal 180 as it is cool here. Normally on a Summer day, air temperature 110-115 degrees I run about 35 pounds of oil pressure at idle after the car is hot. Am I missing something obvious or does the filter make that much difference ?
Thanks,
Ron
