Universal oil

5-30 is designed for gas engines in newer cars. it was developed to produce higher mileage and because internal parts of the engines require hydraulic actuation, ie, variable valve timing. The manual calls for 30 weight diesel oil, however, in the PNW I used 15/40 Delo for 20 + years in my 5432.
