I've been wondering recently whether I should continue with a 0W in our long out of warranty '12 Accord or go to a 5W.
We don't live in an areas where it ever gets cold enough that the 0W qualification would matter and there seem to be some advantages in a 5W-20 over a 0W-20.
When comparing oils of similar brand and quality, the 5W will always have lower volatility, which should help to prevent sticky rings over the years and miles. The 5W will also have a lower VII load, which should lead to less deposits over the years and miles.
Is there any real advantage in the 0W-20 grade?
I'm not sure that I can see one even though this grade is now widely recommended.
