I've been looking at HPL's charts and came across these numbers:
To my knowledge, these two oils seem similar enough to be interchangeable. It seems that they pour/flow/pump at about the same rate when cold and the 30wt has a slightly higher HT/HS. In a climate like mine, the San Francisco Bay Area, is there any real disadvantage to using HPL's straight 30wt compared to the 5W-30? Perhaps other numbers tell a more complete story:
