I regularly use Chevron Techron Concentrate every 3000 miles in all of my cars. If they work, or not, is another question; I also use only Chevron gasoline which is on Kirill's list. MB recommends Techron and another privately labelled one that you can buy from a dealer.
You might have other things causing your sluggish acceleration, but I don't think you can do any damage by trying either of the ones I mentioned.
Another thing you can try is to have a compression and/or leakdown test performed on your engine. With 200,000 miles, your compression might be lower than it should be, which might indicate bad compression rings on your pistons.
