Looking all over for this stuff for the Wife's Subaru. Finally found it(1gal jug) at Sanel Auto Parts in Exeter, NH. Lady at the counter (I think she was a lady ...) said this is expensive stuff. I said if its $20 its expensive and if its $15 its cheap enough (given I was at an independant AP store. She rang it up and said, $13.53. I was whistle'n as I walked out. It's CJ/SM but that's OK since its goin in the car - I would be a bit worried for the PZEV cats with the CI ADD pack. Yipee! I may even do an UOA on it, though total milage is still in the break in arena.
