Brad Penn Green, (20-50) with zink additive is $145 smackers a case in Ontario Canada. It is very hard to find, and has to be ordered ahead of time. The product is not usually kept in stock, and I find it at a speed shop 56 KLMS from my home. I use 14 quarts of
oil every change. With the WIX
oil filter, the cost for an
oil change is a little over two bills every 3000 miles. I'm not wineing, but I think you get what you pay for. Crappy Tire does not fill the bill.
