We bought a 2006 Buick Lacrosse CX 3.8l with 37,000 - 38,000 miles , this last June . The dealer had the oil changed before we took delivery .
Does not appear to require Dexos oil . 3000 miles later , went to change the oil / filter , this last weekend . Took a while to locate the filter & how to get to it to remove & replace it . Then the drain plug came next .
Turns out it is 13mm . Took my 13mm 12 point combination wrench . VERY TIGHT ! Short version , ended up using my largest vice grips to loosen & remove the drain plug ( after which the hex head was pretty messed up ) .
Tried to find a 13mm 6 point wrench this last weekend . Found one , today , at Sears . Craftsman , made in China . Let us hope for the best .
