1978 vehicles or oil are no match for today's technology. But the quality of ingredients sure seem similar between the 70s/80s Mobil 1 and EP of today.That doesn't mean 1978 M1 would pass the same testing that SP GF6A Mobil 1 Extended Performance passes today.
Regardless neither Mobil 1 Annual Protection or EP is likely to be overmatched by an 8 mo 3,000 mi oci.
I never mentioned the AP of 10 or-so years ago. Talk about a short-lived item. Seemed to just sit on store shelves until it was clearanced-out a year or two later.
