Trueog,

I'll dig it out of my storage closet at home and scan it next week. As far as I know, I'm remembering this correctly -- that 10W-30 SJ oil was OK in the M111 up to 90 degrees F.

The chart was in a leatherette zipper case that I only just found this past spring under the trunk lining; I don't know how I missed it during the first 1.5 years I had the car! The owner's manual doesn't have anything but the instruction to 'ask the dealer" for oil recommendations.
