Some times it is better to be lucky than good. I went down to the local WM to buy a gallon of Delo 15W-40 HDEO, they had it for $8.50, to do my semi-annual change on the Bonneville. Been using Rotella but you can't beat the price. While poking around in the oil section I found a 6qt case of The Mobil 1 4T 10W-40 that was stuck behind some car oil. My local store clearanced the last of their cycle oil months ago. I got it at the clearance price of $6.99 a qt. Got a couple of gallons of the Delo for the pickup. Both prices I couldn't pass up. Pays to poke around sometimes. I continue to be surprised that WM stores in close proximity have such divergent stock. My home town store has no cycle section while a store 15 miles away, admittedly a much larger store, continues to have a cycle section in automotive. They only carry Castrol dino 4T oil though.
