i have a simple question about oil on my '78 sc. but im sure the answer is much more complicated
what would be the best oil i could and should put in this car where i DO NOT know the history?.
i don't know what was used in the past (full syn, part, reg)
im not a hard driver on the car, and it will be drivin mostly up in BC, canada (summers only)
i like to find a good oil and always stick with it, but i know different, and older vehicles can be picky with drastic oil changes.
oh... i have 174000 miles with one rebuild some years ago..
thanks for the help.
