Excellent service and excellent product. Been using it for a while now and couple of my friends love it too after I gave them a bottle to try out. All their misfiring, over revving, studdering issues gone.
We have been using Stanadyne Performance Formula All Season Diesel Fuel additive for 15 years and we are believers. We have just tried the Stanadyne Gasoline Fuel Additive on our 2006 Toyota Sienna van and are seeing noticeable results ... better starting, smoother running and less hesitation. So far we have run through two bottles (2 tanks of fuel) on this vehicle which was never previously treated with a fuel injection cleaner. I hope that it continues to improve with more use as the fuel system cleans up. I plan to continue to use this conditioner with every fill up. I also will add it to my small engine gas and hope to see similar result.
Convenient size of bottle to put in the fuel tank of my 2014 Ford Flex
Really good stuff, sure made a difference
This stuff did the trick and made my car and van much more responsive. As usual excellent customer service and quick shipping.
