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.

STA-BIL Start Your Engines! Because Sometimes Engines Need a Pep Talk

Size: 2 fl oz

So, STA-BIL Start Your Engines! is basically that friend who shows up uninvited but actually saves the day. You know, the one who doesn’t ask questions and just gets your engine running when it’s feeling moody or sluggish. Does it work? Of course it does. Like, “put a little in your gas tank, say a quick prayer, and voila!” kind of work. Suddenly your car remembers how to start, and you feel like a mechanic genius without actually lifting a wrench. It’s simple, it’s reliable, and it doesn’t judge you for letting your gas sit around until it gets that “I don’t want to cooperate” attitude. Pros: Makes your engine start like it just had an espresso shot. Easy to use — even if you’re barely awake in the morning. No weird smells or smoke signals, just clean, smooth starting. Cons: Won’t fix your “I forgot to put gas in” problem. Sadly, can’t make your car drive itself to work (yet). You might start relying on it a little too much — hey, no judgment. Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. If your engine is feeling lazy, this stuff just works. It’s like a pep talk in a bottle for your car. Highly recommended for anyone who’s ever cursed their ignition.
