While in Costco the other day, I saw that they were selling a Kirkland branded 15W40 Heavy Duty Diesel Oil. In previous years, they had sold Shell Rotella T4 15W40. I've been on the lookout for it this year, but haven't seen it. Then this Kirkland branded stuff shows up. Works out to $7.66/gallon compared to the Rotella T4 which is about $12.50 at WalMart.
Would you use it in your diesel engines? I may call Cummins to ask. If the spec is the spec, that's one thing. There could be some proprietary "additives" in the Shell that make it worth the extra $5/gallon.
Thoughts?
