Note: Score corresponds to the number of columns “won” by a particular oil. The more columns won the higher the score. So if 2 columns are won, than the score will be 2, if 1 column is won the score will be 1, so on and so forth. Winners are based on the highest amount of columns won thereby in my mind showing the best value.

For gasoline pickup trucks that use 5w-30 you need to stay with oils with the highest viscosity and Amsoil European is near 12cst at 100 degrees so it is near the top of the list for trucks.
Rotella gas truck oil is also a good choice at 11.7cst at 100 degrees
