The most critical time for the engine is at cold startup. 0w is the best oil to use to provide the fastest circulation of oil to the critical parts via the very small pathways. Ford Focus dealers in California recommends 0w20 for their 2012 Focus and their summers are sometimes hotter than in Aus. Sometimes I cannot understand why some people still buy the very popular 20w50 oils for their daily use cars. I think even 15w40 is too thick for cold starts.
