See below oil my recent oil analysis. I ran my 2008 Acura MDX with the oil life monitor to 15%. This was 6000 miles. There are now 34,000 miles on the engine. I had originally gone with M1 5W20 but have switched to Pennzoil Platinum 5W20 with Pureone filter for the last two changes. Oil filter changed every change. Stock Acura Air Filter.
This was a hard oil change. It was -15 F for a few weeks and more short trips. However, I think I changed it early as it looks like there was still life left.
