Tool Pants
The question is which one do you use? I am now in the winter months where I live and there is snow on the ground. My car was just serviced and they used 0W-40, black cap. Are you suggesting that I change the oil to 15W-50, red cap when the summer comes? Why would Porsche reccomend 0W-40 for all seasons if they don't believe it can hold up? I could not see them wanting engine failures on their doorsteps every time they turned around?
Educate me on this if you would!
