and its 16.34 for 6 quarts of syntec. i don't know what weights of syntec pepboys carries, but since pepboys sucks, i'm almost certain that the available ones are the most common. this is about 10 cents cheaper a quart than advance auto's current buy one get one free sale on pennzoil synthetic or quaker state qpower/torque synthetic (advance sells those for 5.68 a quart), but with the advance deal, you don't have to run the risk of having a rebate denied.

0w30 German Castol Syntec (gold) seem to work really well in my 95. FYI, it is made in Germany and is supposed to a group IV synthetic. Car seems to purr like a kitten this winter. May use in the summer. FYI, Check bitog.com for a section on Castrol and otehr euro oils.

which is why i implied that selection might be limited, pepboys doesn't carry GC. i doubt they have anything other than one or two xw30s and maybe an xw40 and an xw50.
