I have used TX 7 for over 20 years. It started in the Sprint Car world (dirt track) and they were a huge sponsor. We got to see all the testing and data. Huge difference when it came time for tear down of the engines. Have ran in my cars for years.

This additive will minimize old burning. Lower friction and engine temperature. Highest recommendation.

I have been using this for years, just found it on Amazon.I use it 20% by volume.It really works but don't add it to a new engine, it's so good it will inhibit ring seal.They have a high mileage formula too.I primarily use it in diesels but it god for everything.I recently added it to my car lift hydraulic system.

Over the years, I've tried them all. But recently a professional driver turned me on to this product and all I can say is AMAZING! Smoother idle from the first start. Better acceleration and cooler engine temperatures too. In fact mileage has gone up slightly also, which just makes me that much happier. This is a great product that lives up to its description. I'm sold! Recommend this for any motor and especially for high performance engines. Well worth the price. Get this!

I use this in my excursion v -10 ,makes the engine run smoother, quieter, and 1 to 2 mpg better.I personally like using TX7 but wish it was a little cheaper.

This stuff is amazing! I was a little skeptical and have been about a lot of additives, but this one really works. It has increased my fuel mileage and made startups nice on cold mornings and no more oil consumption. I am extremely impressed, I would totally buy this again for every car we own. TX7 is what you want.

PolyDyn's TX7 engine treatment is a no brainer. I use a bottle of this on every oil change. My vehicle is 10 years old with over 180,000 miles on it, and the engine works just as good as the day I bought the car. Not once have I had anything on my motor breakdown. If your looking to keep your vehicle for many years to come, I would recommend using this product.
