Saw this at my local Costco (Lakewood, CA) on Dec. 2, 2019. Thought it was interesting since I've never seen it before. Must be brand new. It contains 2 jugs, 5 quarts each for $23.99. Only 5W-30 was available at the time. 10 quarts in total. Very good deal even better than Supertech's price but one must take into consider the membership fee for Costco. Still a great deal.

The membership fee more than pays for itself in gasoline money saved. This is another plus.

Wow.

its actually $5 cheaper per bottle than supertech synthetic 5/30. 5/30 Supertech is $17.47. i wonder if warren understand this might cause a price war on their oil. 3 huge retailers sell the oil they bottle. gonna get interesting

if they start selling 0/20 5/20 its gonna be flying off the shelves.

ST synthetic is $12.XX a 5 quart jug around here.

That means every quart is $2.40. Great price for a Full synthetic 5W-30.

Found these links if you guys are interested. Online it says its $29.99. I saw it at the store for $23.99. I'll have to go back and see if they are still $24 and just pick it up and save the oil for next time. Definitely a Warren Distribution product.
*Great news: They also have 5W-20 and 0W-20 on Costco's website as well.

Why would Warren care if their customers have a price war on oil they've already purchased from Warren? Warren is still getting whatever they charge per unit of oil sold... downstream sales make no nevermind to them?

Warren cares when Wally/Amazon/Costco come back later and say - I see you are selling to the other guys for 5% lower than us, but last quarter we moved more oil than them, so now you can drop the price 8% for us or we're going to buy from Citgo or Amalie. Then in another six months that happens again, etc. A race to the bottom is never good for wholesalers, they have to protect their retailers price margins otherwise those retailers who aren't getting a fair deal will go elsewhere.

Speaking of the Costco membership fee, how much is it? Thanks in advance.

$60 a year basic, $120 a year for Executive with 2% cash back.

I went to Costco for lunch today, and they didn't have the new Kirkland oil. Perhaps after Christmas.

Have we figured out who makes this?

First thread on this same issue began yesterday:

I've been to 2 warehouses in the past week and have not seen it either.
Remember Costco on line is a different business than the physical warehouses.
This oil may not be sold in physical warehouses, we will just have to see.
