it just seems to work. the engines keep running.

My engines just keep running. I have used this for more than four decades I think. The last two cars I bought new and kept for over 17 years each, one I'm still driving. It is still running perfectly with no problems whatsoever with the engine (or anything else really). Can I tell you this is the reason - NO. Do I think it has helped - YES. I just had the recommended measure to my fuel tank with each fill up.

Great for lubricating parts

This is such a wonderful product for an engine. My dad told me when he had several trucks at his business that he got one serviced and the mechanic told him the trucks engine was the most lubricated and well maintained he'd ever seen. Since then I give my car 3 “gulps” every other fill up.

Highly Recommended

I use this in both of my vehicles, a family van and a high performance sports car. It's a great fuel or oil additive to keep engines running more smoothly and improve gas mileage. It's easy to use, with a measured and labeled bottle fire the correct amount each time. It's also a value because one bottle has enough to use multiple times.
