hmm, I'd love to switch back to mobil1 when I'm done with this interval of drive clean. But I'm really having second thoughts on what weight to use. I really don't run extended intervals with oil. I'm even thinkin a synthetic blend might be good. Here's what I'm considering, please consider the conditions of cold winter starts and posible impacts on fuel economy.
Mobil1 0w30
Mobil1 0w40
Mobil1 5/10w30
Mobil Drive Clean Blend 5/10w30
Any qualified reasons to/not to use any of the above?
