So I guess my 14 has 2 bottles in it then, I had the XL-18 for a while just put it in yesterday, Reason is I do not drive the car to much, work home is only about 8 miles, and its not my daily driver, Installed yesterday drove about 100 klms really can't tell any difference at all, I have no problems shifting or missing shifts just trying to get rid of that little nibble in the morning time for the first 5 minutes, after that the shifter works flawless, As someone stated before maybe the 13 -14's have the additive from the factory, This morning I went for a little drive and the nibble was still there no changes at all for the first 5 min,
