The SAE ratings refer to equivalent viscosity rates at 20*C. One thing to look out for with Automotive products is the additives such as detergents and viscosity modifiers most of which are not necessary in other machinery.Walmart has iso32 and 68, otherwise known as SAE10 and SAE20, any Walmart in your neck of the woods?
