I prefer Costco diesel, best price and they carry only Top Tier diesel, but I am lucky having a rare Costco with diesel fuel location only a mile from my house.
Below is a cetane rating for branded diesel fuels that I found on the internet last year ... can’t vouch for its accuracy or how old it is ... may not even be relevant anymore.
I do however try to use Chevron or Conoco when out of town just in case this comparison is accurate.
BP (Amoco branded), 51
Chevron, 49 (51 with Techron D)
ConocoPhillips, 48 (California 48-53)
BP, 40-42 (Powerblend 47)
Husky, 40 (Max 41-45)
Sunoco, 40 (Sunoco Gold 45)
Holiday Stations, 40-43
Flying J, 40
