I have about 150 hours to go before my next fluid change and would like to have maybe a gallon on hand to top things off. I'm not losing any but if I needed to add some at any point I would not have any. The place I bought it when I did my first service only sells in bulk. Another question. If I found some Mobil 424 in quarts would it hurt to top off with that?
