0W-20 OOS everywhere I check, but was worth a shot. Thanks.

Same. I think I am just going to wait for the Costco oil sale and grab some 0W-20.

Usually, what time of the year does the costco oil sale happen ? I would like to wait as well if it is anytime soon. Just observed it has gone on sale in April/August last year. Hope the sale is not over already yet. Did not see a drop in price this month yet at the local Costco

Bought 2x5w20 at Anaheim, CA store just now. They were not on the shelf and clerk said they still have 3 in the back.

Got two 5w-20 and two 5w-30 at store about 15 miles away. No 0w-20 avail. Was only $4.95 extra to have it shipped so I did that. Cheaper than driving there.
