*Looks like QSUD ($17.xx) and Magnatec ($19.xx) per 5 qrt. jug are now everyday prices at WM (or have been on "roll back" at WM for longer than any oil I can remember? I bought jugs of each in 5W30 to try in my Hyundai GDI 2.4L fuel diluter , soot creating 4 cylinder which I can only realistically run for 4K to 5K mile OCI's in mostly large city suburban driving . Both a D1/Gen 2 rated and with the only differences being a shot of titanium in the Magnatec add pack along with "clinging" oil molecules while the QSUD (according to 540 RAT) has superior lubrication to just about any synthetic oil tested ... Probably just a case of picking which ever one you fancy best for a OCI of <5K miles in a GDI engine ?
