All,
I've been using the cheapest 0w20 oil that meets Subaru spec that is readily available without rebates. It was Supertech 0w20 for $14.37 for a 5 quart jug for my last oil change.
I've heard the news that Costco is selling 2x5 quart jugs of their house brand oil for $30 online and $25 in store. I've only seen 5w30 in the warehouses.
Has anybody seen any other grades in a Costco warehouse besides 5w30? $12.50 per 5 quarts is an attractive price, but l will settle for Supertech if l cannot get it in the Costco warehouse.
