That being said, the engine is not a known for oiling troubles and while i can make anecdotal claims that say everything is dandy, my ocd would at least stick with any oil type just change it every 6 months.
Ideally i would switch to mobil 1 0w30 esp as its an excellent oil has the approvals, in vehicles whose certification standards are tough to meet.

why would you want to use a BLEND, that is the question? and on a RCF?? To me, no sense. You do know that a blend is basically just 10-20% synthetic. It's a marketing tag. It's not like you're saving money all that much. Go FULL synthetic and stay w/ your annual oil change interval. Amsoil Signature Series is one such real definition of Fully Synthetic. Pennzoil is another good one.

Hopefully I won't get too much flame for this. I've been using Euro spec 5W-30, due to reports about some fuel dilution in the 2UR-GSE engine. Euro oils are slightly thicker than many recent 5W-30 API SP/SQ oils that come with Resource Conserving feature. Fuel dilution will make euro oil go out of spec slower.
But euro oil or not, I still stick to at most 1 year/5,000 mile oil change.
