Have been a Valvoline Syn user for some time now. Since my vehicle moved over 75,000, on my last oil change I switched to Valvoline MaxLife Syn 5W30 (at 78,000). I will do a Oil Analysis between 5,000 to 6,000 miles and report results.
I'm curious why you decided to go with a 10W30, instead of 5W30. It seems you would have a little better start-ups with 5W30 in cold Ohio. Also what filter are you using?
