Yep, that's all pretty true. Generally speaking, though, if I have to read a product description that carefully and there's some confusion as to what I might be buying or the product size and/or the price are totally out of line, it's time to find another supplier. At brick and mortar retail stores, when it comes to oil, some people stocking shelves can't tell the difference between PP 5w-30 SN/GF-5 and the Euro C3 5w-30. The last thing I need is someone similarly [un]skilled fulfilling an online order for me.
