Living in Illinois, I was happy to see that 0W weight was spec'd for these engines as I drive my car when its cold. I learned several years ago how much faster 0W oil flows when we had a piece of equipment that was faulting out on initial start up for low oil pressure when it got below 0. We switched from a 10w to a 0w and the problem went away. BTW, the fault was for low oil pressure for 15 SECONDS!!!!
