The oil aisles in the "blue" big box Marts in my area have looked like the the bread or milk aisle on the eve of a snow storm for that last month. The engine oils are still available, but I cannot find 75W90 gear oil for the differentials and Transfer case at all. I can still find the more expensive stuff at the auto shops, but the Supertech and now the Valvoline 75W90 is out at every WM in the Metro. I still need 4 qts to finish up the 4runner and the wife's RAV4. Anyone else seeing this?
