Works well always use it and all my equipment

It's a very good product for my European car. Unfortunately, it arrived with a small leak, even though it was sealed.

been using this product for years and seems to really stabilize the gas over months

Use it for years, it’s perfect for outboards and other small engines. My old evinrude 48spl ran so much better with this additive, noticeable improvement. I add it to all other engines- jetski, old car, riding mower. It does well for maintenance. The great thing is it definitely cleans carbs as it runs— helping those old motors!

This stuff works great! Not just my truck but my lawnmower, edger, trimmer and blower all work better

I use this to pretreat gas that sits in a shed at a remote cabin. When My jeep sat unuseded for 2 years I just added this to the tank and within a few minutes (10 - 15) of running the engine went from stumbling to purring. A generator that had a full tank and was only run for a few minutes at a time started to run rough so I added this to the tank and she started running great even under full load. I'm sold on the StarTron Fuel Treatment. It's not a replacement for fixing worn out parts or clogged filters. Check your points, plugs, fuel filter and air filter as well as servicing the oil at appropriate intervals (more than onece a decade)
