5w20 vs 5w30 Oil
 

I am just curious as to what type oil everyone is using. I was doing some search and I found this online.

"Every where else in the World (except in the USA) Mazda requires in the RX 8 Owners Manual the use of 5W-30 oil to adequately protect the very same hot running rotary engine that is in RX 8's in the USA. The heavier oil protects the engine and oil seals from failure and prevents oil blow by from ruining the catalytic converter, for over 200,000+ miles, as documented in many forums on the web."

So is everyone using the recommended 5w20 (by the USA) or 5w30. Please chim in at your convenience.
