anyone run Costco diesel? The price is good, but I don't know about the quality. We have other options in Indiana (shell, BP, marathon, rickers etc) that will suffice, should the quality be better. It's hard to know what you are getting.

 

Some of our Costco's in WA now sell Diesel, and yeah it's almost always the best price. I have fueled up a number of times there, and have had no issues with their fuel. My local Costco sells a lot of D, and it's always moving.

Costco likes to say they have their own fuel, or at least their own brand of fuel, but again in my area it's Shell fuel. In Indy the Costco in Carmel was using Marathon fuels. If you use their D, I would say you should be good.
