Is this a bad idea? Should I bump down to 5W-30?
Now I only put maybe 6k miles on my car per year, which means a once-a-year oil change. Meaning, the next time I change my oil won't be until about the same time next year, so this oil would also be used through the summer (60-100F).
I can't find 0W-40 here. All I can find is 5-30, 10-30 and 10-40!
What do you guys recommend I stick with? This is an 01 with 73k miles.
