Engine oil

Ed, I saw your comment regarding early engine oil. My '67 911S has been running fine on 15-50w Mobil 1 for years without any leaks or problems that I have noticed. Switch to diesel grade or racing? Also, my oil pressure gauge has always (25 years) read very low (10-20 lbs.) at idle. It never shows above 40-50 lbs. when running. Sending unit problem? How would I check?
