After sensory overload on all the pros/cons/beliefs/philosophy/thoughts on the 5W-20 oils, I was wondering about ACTUAL performance. I'd like to know what kind of car and engine, and brand of oil you've been using and how many total miles driven on 5W-20 oil. I'm just curious because there seems to be a strong power curve of individuals that simply don't trust this oil and use something thicker like a 5W-30 or 10W-30, etc. etc. Wondering if any one has noticed some problems already, for those of us that have stuck with the manufacturers recommendations. Me: 2002 Accord, V6, Quaker State, 36K. No noticable problems so far.
