It's cheapest near Ann Arbor, Westland, and Monroe I think. I think I squeese slowly until I have a total of 15 gallons packed in my tank. Read the directions and it might tell you that you can double the amount in the white bottle if you want to. You can use the recommended amount, and if you want you can add the recommended amount of the Silver/gray bottle that is mostly for summer to increase the cetane, and lubrication to increase mpg, and starting ease. I use 10 oz of the silver bottle in summer, but I haven't used the white bottle yet. Last winter I didn't use anything but the silver bottle, this year I use what the VW dealership sells the Stanadyne Performance Formula. I think I will switch to the Power Service white bottle when I run out of the Stanadyne though.
