Re: 5w50 too much?
If living in Texas, Id recommend 20w-50. You wont have to worry about cold morning starts that require 5w- oils. The 50w will tend to help out with oil consumption if that is an issue. Has the engine ever been rebuilt? what modifications? more info. would help. Stick to oils with higher ZDDP than conventional oils offer too. Your flat tappets will like higher ZDDP alot, (with no catalytic convertor). DONT use an additive to 'add' ZDDP to your oil, that will mess with the chemistry of the existing oil, not help it. I would recommend AMSOIL's ZROD oil
When you get back home , before winter sets in, change to a lighter oil. 5-30 or 40, depending on your needs.
