With that said,I used M1 10-30 HM in my very high mileage Mercury and did a UOA with good results at 9400 mile OCI. If you want the details on the UOA let me know.
Naaahh the motor has used maybe 3/4 of a QT every 3k of Mobil-1 since it had low miles on it...I have no doubt that M1 has protected this motor well since it doesn't smoke or run bad and looks clean in the valve covers...but it has always used oil since nearly new and MANY other people on the net in a variety of different applications report the same thing whereas M1 burns off and then they try another brand and it doesn't. You know that from being on BITOG surely?
BUT I am more willing to accept this since the vehicle will not be a DD anymore it will not really be an issue. I can say that it was M1 silver cap that I had this issue with and I began rotating M1 every-other OCI a couple years back. I am not 100% sure M1 HM will burn off as fast as the regular M1 though...But again less of an issue with a non-dd...
I just want to know if M1 HM will resist moisture, oxidation, and fuel contamination more than Maxlife blend cause I need a good oil for a vehicle that sits alot.

Yeah I can get it at O'Reilly's but I have always run M1 so I am gonna stick to that for a HM oil unless Pennzoil releases a PP version I guess.
