Really?

Wonder why my owner's manual shows SAE 30 (single grade) for temperature
range 32 F to 95 F ? ....
.... and SAE 10-30 milti grade for temperature range 0 F to 60F ?
.... and SAE 5-30 multi grade for temperature range -20 F to +15 F ?

Perhaps you would recommend to VW that they change the owner's manual? :)
