Are use this rebate last fall with no issues. Walmart seem to have the best prices I could find. 12 quarts for just under $50 and the 5 quart jugs were under $23… Possibly under $20 each. I have enough on the shelf for 2.5 oil changes and don’t expect to be putting many miles on the car so I probably won’t be buying more for the crossfire with this rebate.
