Seriously? "thin as water"? :h
This might have been an issue 50 years ago (remember back when a 3,000 mile oil change interval was actually recommended?), but with today's technology it's not. Oil gets hot regardless of the weather. The engineers at Ford recommend (actually they insist on), the 5W20 because it is the best oil for that particular engine (with its high RPM - close tolerance design).
:C
Yes! Ever change HOT 5W20 oil? Yes it comes out very very thin, just like water, maybe not as thin ,but you get the picture. 5W30 does not thin out as much.
And back in 2000 the required oil was 5W30, then Ford did a change to 5W20 for nothing more than to say it helped mileage. Which one person will never actually see! And even then the cars that were switched over had nothing to do with CAFE requirements because they were already on the road.
Chrysler did the same. They switched to 5W20 on some cars to increase CAFE that's it!
