Unless your coolong systems are inadequate or defective, there is no reason to use any oil "heavier" than 10w-30. Mobil makes a great 5W-30 if you want -30F pumpability. I used to swear by 20W50 oils for summer protection too. Then I listened to some engineers and was "converted". woof Radek <radeknopsamr.ca> wrote in article <iO%u2.46$7Y.239804nopsamRead.Toronto.iSTAR.net>... > Has anyone heard about problems with using the 5W50 synthetic oil?
