Hello. New guy here diving into the world of oils. I've always been kind of old school when it came to oils...used conventional and changed every 3-4000 miles. I figured I drove enough to warrant it. Usually that equated monthly oil changes My question is my wifes new car is a Toyota Camry calling for 0w20. I can only find synthetic. Question 1) Is this available only in synthetic? (now I'm using Mobile 1 Advanced Fuel Economy) 2)I thought I read somewhere (maybe here?) that synthetics have the tendency to "fling off" and not really stay on the moving parts as well as conventional oils. Is this true? I've often wondered about this as many prefer the synthetics on start-up. Does the 0w oils "run off" parts easier during sitting over night, etc. where as say a 5 or 10w oil would more likely stay on things better for that instant lubrication? Thanks in advance and thanks for a very informative forum.
