Diesel oil has been hard to find at the WM's near me. The other day I was buying this at $18.24 and it's now $24.48. I'm lucky to even find any 10w30 diesel in stock around me. My last OCI, I had to go with 15w40 because that's all they even had. Unfortunately I think this will get much worse before it gets better. Is everyone in other states having this problem at WM too?
