Does what it says
Size: 16 Fl Oz (Pack of 1), Style: Individual
Have a JD 280 and it was not running well at all. Surging, not running good overall, where as previously it was. I used this and after a few hours of running, it cleared up very well and runs like a "Deere" now. Product line is still, one of the best out there. Bought again for my chain saw and use it in my weed wacker too.
