I heard that it "POSSIBLY" could be Quaker State.

Ken,


I spent a couple of hours researching your question, and all I can say is wow! There is a bunch of debate about this oil. If you go to http://theoildrop.server101.com/ubb/ultimatebb.php and do a search, you will find that they have OA results with the oil and give it a favorable review overall. I think the consensus is that it is made by QS/PZ.

FWIW i was at walmart today, good selection of diesel oil, and they had power service diesel fuel additives on the shellf. I use primrose, but was kinda surprised they had PS on the shelf.

Sounds to me like it is API rated for our diesels-Good quality oil-inexpensive- and possibly even made by Shell. If you change it about every 5000K miles, how could you go wrong?---Ken
