Oil for new cars
My new Ford recommends using 5W20 oil. It's the only oil they mention. I read an article that says life is much worse with 5W20 oil than 5W30 oil and said only Honda and Ford recommend using it and they only have 3 years / 36,000 mi. warranties.
For some of you with newer vehicles (2006, 2007) other than Ford or Honda, what oil does your owner's manual recommend using? Does it still have the multiple options based on temperature?
