Alan, are you comfortable with the smaller
5W molecular size for the 5W-50 syntec? I've
run this in my MBW during winter - I live
in Minnesota - but during warmer months
switch to 15-50 Mobil 1, or 20W-50 synthetic
Valvoline.
Since the M37's like a heavier oil for a thicker
oil film, and since they tend to be run less
often than most daily drivers, I'm more
comfortable with the heavier oils, whether
synthetic or organic.
Seems like that 15W-50 Mobil 1 would be an
excellent choice except perhaps in sub-zero
weather.
But then again, you'd have to be really hard
core to want to drive an M37 in Minnesota in
January!
You've always been a great help to all who own
and love these trucks. I just wanted to offer
my two cents worth.
Thanks again for all your help, Alan.
