for years and years the rule was no synth in any older engine due to the rope rear main seal. I use sae NON DETERGENT straight 30 wt oil 5 qts + 1/4 to 1/2 qt of lucas eng oil additive, changed once a year on the limited use classics and 89 octane fuel with lead substitute and a splash of marvel on fueling and have had great results on unmodified original engines. I dont drive vintage cars in the dead of winter so I see no need for multigrade oils. make sure the cooling system is full to the top and wire the exhaust crossover closed on these vehicles when used in the summer heat!
