It says what it does and does what it says.
My old flathead six never ran better.
If you buy this for the stated purpose, you'll come back for more -- I did.
I own a Chriscraft (1963, T327 ) inboard that hadn't had much use for a couple years, and I needed to run it 80 miles to it's home dockage. After several failed attempts due to motor problems, and after all the usual things were checked and adjusted or cleaned, I added Startron. After the 80 mile run, it ran great and still does.
I did have to readjust the carbs after the trip to lower RPMs, probably due to cleaner jets, but that's about it. Now I'm down to the one 8 oz bottle for every 250 gallons of fuel, just to maintain the system, instead of the the initial 8 oz per 120 gallons, and I convinced my local marian to start carrying Startron.
This is a great stuff, I will buy more. I currently use it in my boat and diesel pickup. I have notice and increase in mileage and smooth operation of both boat and truck.
Last spring I had the carbs on my 2002 merc 40hp 4 stroke re-built due to hesitation and overall poor running. I got it back and it ran ok, just ok for most of the season. last fall I bought some Star-tron and put it in the gas. It seemed to run much smoother no more hesitation. I stored it last winter with startron in the gas. This spring it started right up and runs perfect. I really think the startron is great. I put it in my 4.3 mercruiser (carburated) and the motor has never run better! I'm definately a believer!!

I can honestly say i dont know if it works, but what i can say is that i keep my engine in top condition all the time and have been using this stuff since it came out due to the oxygen additive and had no problems so does it work i dont know but i will keep on using it thats for sure 150 merc o.b.
I usually complain more than compliment, but in this case I have to take my hat off and bow to this stuff and write a review.
I have been using Star Tron for about 6 months in my boat (1999 Yamaha 200 outboard 2 stroke.) Right away I noticed that it was easier to start, especially when I let it sit for a few months during winter. It also runs smoother. Very noticeable and will keep using it in boat. (I used to have to Starting Fluid and change the plugs if it sat for too long, bad I know :( but now it just starts quick every time like it was warmed up.)
But the big visible difference is when I put it in my friends F150 pickup. It was running poor with hesitation and sluggish. I thought it was going to stall in the middle of an intersection. It always died on hard acceleration. I put in ONE treatment of Star Tron. Half a tank of gas later ALL THE PROBLEMS WERE GONE! Not just less, but GONE! We were both shocked actually. I thought it might help a little, but it went way past helping.most of my friends carry a bottle in our trucks.
ALSO, I use it in my lawn mower, weed eater and chainsaw. They run smoother and always start after sitting.
The first fuel additive that really does something noticeable.
It's hard to review something that prevents bad things from happening but I've been using this for a couple of years on my Johnson outboards (2 and 4 cycle) and have no water or storage problems
