I pick up a gallon here and there from time to time. A month ago I picked up a gallon for 17.50 plus tax. Then about a week ago I picked up a gallon at O'reilly's for 17.99. The first gallon came from NAPA. Yesterday I changed oils in my pickup and dozer. Travelled to WAlmart picked up 2 , 5 gallon pails for a per gallon price of 12.78. I did have to drive 16 miles round trip to Walmart but I saved over 50$ on the oil , and picked up the latest Guns and Ammo magazine. I'm not a big Walmart fan , but what else should you do. What prices are any of you seeing for oil. I don't need to buy in bulk or even a 50 gallon drum. Maybe a 30 gallon drum would do me 6 months plus. I thought 5$ difference was rediculous.
