I want the most watery-thin oil for winter and I don't care about its properties at operating temps. I've been using M1 0W-30 (manual calls for 5W-30), but I read on this board that, for example GC 0W-30 is a 'thick' oil and that PP 5W-30 is 'thinner' than M1 0W-30 and that M1 10W-30 'flows better' than their 5W, etc...so which oil out there will enable the engine to crank over the fastest? Again, I don't care about what happens once it's at operating temps.
