So in warmer climates, like the Houston area, wouldn't it be a worthwhile trade-off to give up a little mpg to protect the engine to a greater extent by using 5w30 instead of 5w20?
I'm running Royal Purple, BTW. and will be switching to RP tranny fluid and rear diff fluid as well (it comes with the friction adder already).
Your thoughts?
