Zero Weight Oil
THe 0w only refers to pour at lower temperatures. Both 5w20 and 0w20 should have the same viscosity at operating temperatures. From what I have read on "Bob is the Oil Guy", the 0w is a superior oil due toa betteradditive package. I am running it with 10k mile oil change intervals...
I changed my oil to Mobil 1 0W-20 weight, and noticed a .6-.8 mpg increase on average over the last few tanks of gas. I used the Mobil 1 filter, as well... Haven't quite decided on a drain interval yet. Any recommendations?
