Perfect, probably just what Jim needed to see. I tend to error on the side
of caution and tend to use the best products to prevent inadvertent
failures and get lots of Mile's out of my cars.
Most dino oils work great in water pumpers as oil temps rarely could ever
get above even  180-200, due to water cooling  but our air cooled engines
get the oil temps there almost every drive.
