Hey everyone. Two questions. Have a 99 WS6 with 24000 miles. The last month of driving (it's hibernating now
) my oil pressure was pretty high. More times than not inbetween 3/4 and all the way. It never pinned the oil pressure line even with higher RPM's (not redline). I don't have too much oil in it, if anything it's a tad low. nothing major though. Second question, I put Mobil 1 Synthetic 5w-30 in it. How long should i change this oil? i used to change it on my 95 formula every 3000 but it gets expensive and my father says it's a waste of money every 3000. Any input? Thanks
