We were surprised to see the Kirkland Signature Full Synthetic SAE 5W-30 Motor Oil in the store.
At first glance, we thought that the Kirkland oil was priced about $4 cheaper than the Mobil 1 motor oil with the current rebate.
But upon closer look, it’s actually much cheaper than that.
The Kirkland Signature motor oil comes in a 2-pack of 5-qt bottles for a total of 10 quarts and $2.499/qt.
The Mobil 1 oil is available in six 1-qt bottles for a total of 6-qts and $4.782/qt (with the current rebate).
So, the Kirkland motor oil is actually 48% cheaper!
We only saw the SAE 5W-30 in the store but Costco offers the Kirkland SAE 0W-20, SAE 5W-20 and SAE 5W-30 online at Costco.com
The Kirkland Signature Full Synthetic SAE 5W-30 Motor Oil is priced at $24.99 for two 5-Qt bottles.
Unit price is $2.499/qt.
Item number 997930.
