All I do know is that MaxLife has an add pack that most of it does not show up on an oil analysis, and it is a Dexos rated oil too. On the other hand, a lot of the add pack for Pennzoil HM does show up on an oil analysis, and it is just SN rated and not resource conserving either.
If the rain will ever stop, I will get the MaxLife blend in this week, and I plan on using it for 5,000 miles which is the longest I have ever gone between OCI's.
That is interesting. It will keep a louder engine quieter for the full OCI because in theory it won't thin out like resource conserving oil does.
I might try it in my 12 Jeep Patriot.
