No doubt this is true, but I don't recall seeing this recommendation in various Haynes, Chilton, Motor, or other repair manuals specific to given models of cars or motorcycles. When formally schooled, mechanics may learn the SAE recommendation, but the self-taught home mechanic is (I don't think) reminded in the manuals I've seen, though they are intended for home mechanics rather than shop pros. Then again, I could be wrong. The last time I read a Chilton manual from cover to cover (1979 Honda CB750F motorcycle), was about 20 years ago.
