Electric Impact Wrench, Valvoline Maxlife Synthetic

I just picked up a "crappy tire" electric impact wrench on deep discount (C$50 down from $150). Do I need impact sockets for this thing? I need 21mm to take off wheels, and maybe 19mm if I am to do my own struts (It can do 240lb-ft). What other sizes I may need to service my two pigs? (see sig )

On the same occasion I also grabbed a jug of Valvoline MaxLife Synthetic, also at discount at C$19.79, and purported to be a crappy tire exclusive like M1 EP. Is this good stuff? I know there's regular MaxLife and to pass on those.

get impact sockets, you can get a set called a flip set that has the 4 lug nut sizes needed rolled into 2 sockets which 'flip'. one pair is metric and one is standard. it includes a small extension.

Hey, my trolley jack kit comes with two such flip sockets and an adapter piece that lets me use the trolley jack handle as a breaker bar, only it isn't impact.

21 is for factory lug nuts and 19 for the smaller aftermkt lugs.
