I changed my oil yesterday, and I used a K&N oil filter and Mobil 1 full synthetic. Now everything went fine(filter fit and all), but when I started the truck the oil pressure went much higher than I remember it used to go. Just wanted to know if anyone had this problem as well. It dosen't ever peg out the needle or anything, but just quite a bit higher. I'm sure it isn't the oil because I used 5w-20(what Hemis need apparently), so it has to be the filter. Any insight would be great, Thanks.
