Jeff, I personally believe straight 30W is too thin of an oil for a spit
engine. Every one of my books recommend 20W50 for yours and all the spit
engines. I run castrol 20W50 in all my LBC's. Since your in warm climate,
I would recommend it. If I understand multi-viscosity oils, its 20W when
cold, 50W when hot. 30W is even thinner than the 40W of the 10W40.
