Ralph, you're proposing the 'best available' solution but I'm not convinced these 40+ year old antiques need anything better than generic quality, the sort of stuff that Tractor Supply sells a lot cheaper than M1.Millions of VW TDIs running around with 5w30 in their crankcases. What I run in the 2025R Yanmar engine and in our Isuzu generator driver.
In future, I plan to try to get 0w30 (probably online) M1 ESP. In past, I was getting the 5w30 Castrol for VW TDIs from the VW dealer.
And - while a passenger car isn't run hard enough to exceed 30 weight oil capability, these may continually be run so hard, rototilling etc, that they can barely maintain rpm. So if it will see extreme hot weather, the 15W40 widely used in road semis seems more appropriate. Are truckers now moving to 5W30 etc for semis?
