READ THIS IF you use Redline oil and Puralator

luigi90210

both redline and M1 0w40 meet the same european standards

it says it right on the box and on their websites, i could careless about a used oil analysis report, that doesn't mean anything if you change your oil every 3750 miles

if you like redline, thats great, i dont really care
no need to flame and be a fanboy because someone disagrees with the price associated with redline

EDIT: after looking at your posts it just proves what i said, you're running your oil much longer than you really should be and all i see from your reports is redline is overkill for the engine, its like running a 34row oil cooler on a N/A 370z that rarely sees track time

EDIT2:
looks like mobil1 0w40 meets many higher ratings that redline 5w30 european oil dont meet
again i got this from just a simple look on both manufactures websites
