Hey Don,
You also have to consider the design of the engines. Low ZDDP
mostly affects "Flat-Tappet" designs (think Harley Davidson or flat 4 &
6 Porsche). (FYI -- ZDDP=Zinc dialkyldithiophosphate)
Here are some examples:
Valvoline (VV150-6PK) MaxLife 10W-40 Higher Mileage Motor Oil. ...
Pennzoil High Mileage Vehicle Oil. ...
Mobil 1 45000 5W-30 High Mileage Motor Oil. ...
Castrol 06470 GTX 20W-50 High Mileage Motor Oil.
Also, try Allen's suggestions or google high ZDDP oils.
Good luck!

For old school NON-MB (cast iron block) and 1984 technology would shell Rotella
(or something similar) be best because of the higher zinc content?
