There have been some charts on the forum that show that the cold pour point of Shell Rotella 15/40 is the same as 30 weight oil.I put some rotella in my tractor and pick up in December.When I started the pick up the oil pressure was all over the gauge.Seem to have trouble picking up the oil,never saw that in the truck but noticed it often in hi milage engines after an oil and filter change.Many years ago I was putting the top on a transmission in a cold garage.I kept a jar of 40 weight oil to smear on gaskets.I stuck a screwdriver into the jar to pick up some oil,The screwdriver stood up in the oil and left a hole when I pulled it out.I still wonder if an oil pump could have pulled that oil thru a screen on a cold start up.I put some Chevron 10/30 and a new filter in the truck this time.Its hard to say one brand of oil is better than another because a lot of it is bottled in the same place.My father in law had an oil truck during the 30s.He sold kerosene for 8 cents a gallon.He sold motor oil in 2 and 5 gallon cans There were special oils for Fordson tractors.Oil had different prices and names.He went to get a load of kerosene and motor oil.He went into the office to place his order.No one in the office at lunch time.He went into the warehouse and saw all the cans lined up near a spigot.The single pipe went up to an oil tanker on the RR track.A hose connected the tanker to the pipe.It was obvious that all the cans were filled with the same oil and sold at different prices.
