(don't need the 0W where it gets to freezing only twice a winter)
Not really true. The viscosity of even 0w engine oil is too thick to lubricate properly when it's below operating temperature. The large majority of engine wear happens at cold startup, and to reduce that wear as much as possible (can't avoid some wearing), you want the thinnest oil you can get when cold that still provides proper lubrication when hot. All cars can benefit from 0w oil. My Integra calls for 5w-30, but I've been using Mobil1 synthetic 0w-30 for over a decade now. Car has 369,000 miles on it now. And I use OEM Mazda 0w-20 in our CX-5 with 92K miles. I just recently got a Blackstone UOA and they said everything looked good and to go 8,000 miles on this next oil drain interval.
