I was at Costco today and saw they had their house brand Kirkland engine oil onsale. Two 5 qt jugs for $30. I already did an oil change last month with Penzoil Platinum Full Synthetic 0w20 but I've been wanting to give Kirkland a try. I picked up a box of 2 and will give it a shot and get an oil analysis of the Penzoil coming out as well as the Kirkland to see how they compare. Probably won't have the results until late in the year on my 2016 Yukon SLT.
