Gm tracks your loyalty by cost billed out vs what you have purchased. If you bill out more oil cost than you have purchased you, may get insufficient purchases and that will count against your loyalty. Theoretically you should be fine billing pints as long as you adjust you cost per unit accordingly. If you really wanted you could even bill it by the ounce such as dexos 5w30 bulk 19293002 at 10.59 cents an ounce for cost.
