I was doing some research on M1 High Mileage and Valvoline Full Synthetic with Maxlife...both in 5w-30 flavor. Problem is that all the thread I kept coming across were several years old. I tried to revive one to avoid cluttering up things with a topic that's probably been discussed many times. But apparently that is frowned upon.
But it seems like a few things have changed over the years and it might be worth discussing. And please, no cynics. Just civil discussion.
So here goes....those 2 oil in that weight are what I would like to discuss. '15 Toyota Tacoma with a 4.0 V6....5k OCs with either an M1 or Fram Ultra filter....whichever is available and/or on sale. As I approach and soon pass 100k I am considering a HM oil. The rig has spent most of it's life on vanilla M1 or Valvoline Synthetic. A couple of M1 Truck and SUV changes when I found it for cheap.
From what I can gather....Maxlife is the granddaddy of HM oils. M1 HM was a very robust product at one time, but may have been watered down some to meet SN/SN Plus requirements....and greatly reduced zinc levels too. In fact, it's zinc levels are the same as vanilla M1 according to their site.
If I remember right...VML has a viscosity of 10.8 @ 100°C and M1 is at 11.7.
So what do you experts think? Is the heavier weight of the M1 a plus for it? Is there more to all this than a layman like myself needs to know?
