Smaller oil blenders like Warren Oil, Warren Distribution now Warren Highline aka much higher prices actually, Smitty's Supply, Amalie, Omni, Pinnacle Oil, Olympic, and Martin Lubricants.
And daggone there's one in California that makes a oil for some gas stations. Race Pro oils is the oil they make for those stations. Have to look up that one.
These all make legitimate very good API and Dexos rated oils. Some of these blenders are not the best with Euro spec oils. In terms of saying their oil is suitable for a MB 229.5, BMW LL-01, VW 508 or Porsche C30 etc etc... When it's obvious they don't have the real approval.
