Walmart and VIP have it around here in the winter. My dealer usually orders in a case or two a winter for me and says I'm one of the only people who ask for it. Man do I hate it when it warms up and my saw is full of low temp oil, the huskys are leaky enough. Nothing like having a whole tank of oil on the floor.
Put some JB Weld on the seals of your oil tank...my only thought
