What grade oil are you guys using?
 

I live in metro Atlanta and am working on purchasing an RX-8. I was wondering what grade oil you are using, especially during the hot summer months?

I'm leaning towards Castrol GTX 10w40 dino or Brad Penn 10w40 partial synthetic...

10 40 is a very good choice.

read this.. https://www.rx8club.com/series-i-tech-garage-22/cumulative-synthetic-oil-discussion-52856/ and the 100000 other posts about oil. Will give you an idea of what kind of oil will suit your climate and driving style

Yeah, I've read the bulk of that thread.

I was posting specifically in the SE forum to find out what folks in the region run in summer and winter. Figured i'd be easier to cut to the chase then spend hours trying to find a straight answer...

I used 10w30 when in FL and now living in NC I'm using 5w30....

A number of smart minds have been using 15w50 Diesel oil for good reasons mentioned on other forums. I'm going to go to 10w40 at my next oil change.
