Never got caught up in that, since never used Delo; did they still have CF2 in the API doughnut after they reformulated?
I guess a better way of saying it is that if/when the refiner changes the descriptive labeling, beyond the API doughnut, that should be one clue, calling them would be the next step. Many of them, such as Valvoline, also print the specs, such as Ash, viscosity and TBN online. My plan is to keep the list of stuff we know works today and continue buying those.
As far as DD PowerGuard, you also want to be sure you get the 2cycle version. The DD place in Rhode Island gave me a bucket of non-2cycle 40W once. Florida DD and J&T in Baltimore always had good supplies, but that's been close to a year now.
