Yeah that SF oil was intro in 1980 , thus supposedly unsuitable for engines after 1988/89 era .
For the most part a engine is stupid, has no clue what oil is used... Probably with no exception 1990 engines were no different than 1988(I know the Fords were same), but yet it's said they could be damaged by using earlier oils... Mostly a Chicken Little "the sky is falling" routine..
Somehow, Shell Helix HX3 SF can read your engine features ............
