Oil grades? We have a 1979 Newell with 6V92DD (non-turbo) with 105K miles. Althought the engine is superb - the oil pressure has always been lower than I would like to see - approx 15 @ idle and 35 at cruise. We use Mobil 40 Wt - 2 Questions - Would the Del Vac 1 Multivis cause the oil pressure to drop any lower? And, is there anyway to improve the oil pressure?
