That's why you don't tell the the oil or even the grade. Make them determine it from their tests. If they give you numbers that are completely bogus. Ask them to retest.
Yeah good point. In the case of my UOA, OAI didn't know it was Quaker State. The form asked for the manufacture of the oil and I wrote in SOPUS lol.
