Is there any advantage/disadvantage to using a 5W-30 over 10W-30 synthetic.
Thanks
Thanks
Even if it only gets down to 40 or 50, the 5w30 could help.quote:

Great question. But the qualifying statement in your question is "since a good 5w30 synthetic will not thin out". If the oil is good quality, I don't forsee much difference at all.quote:

What advantages do a 10w30 synthetic have over a 5w30 synthetic? I say none, since a good 5w30 synthetic will not thin out.
Well that's true. But a 5W-30 is 60 cSt at 40 F and 10W-30 is 65 cSt at the same tmperature. The difference between 0W and 5W is too little to see on the graph.quote:

This is exactly what I'm doing, not only in my own car, but my entire family's cars! (wife, mom and dad, and sister until she sold her car and moved west)quote:
EDIT: I want to change my statement slighty. Why not just stick with a quality 0W-30 and skip the other two, regarless of weather?
