So I have on hand a jug of SL rated M1 HM 5w20 and SL rated M1 HM 5w30. Almost at 4,900 miles so will change oil soon and leave magnets and Bosch d+ filter on. Which M1 HM would you folks use thru winter? Already saying this winter will be "milder" and warmer than last winter here in southwest PA
THANKS in advance
