Hi MorrisTigerson69
Use 20w50 in summer and 10w30 in winter. Use a good brand like Castrol GTX or Castrol Syntec Blend. They are moderately priced. Mobil synthetic is very expensive and may have a lot of polymers. Advantages and disadvantages are explained by our friends in the earlier posts. It is still the same as in 1990s.
