Engine Oil Additive Restoring Your Engines. New Engine Coating Technology based Carbon Nano Tube(CNT) with Nano Platinum. (For Any kinds of Car, Truck, Tractor, Ship and Motorcycle)

I bought Z-flex engine oil additive in March after my 2003 Silverado mileage dropped to 15.4 mpg. After adding Z-flex my next tank got 16.6 mpg, the next one got 18.3 mpg and today i got19.4 mpg on a 30 gallon tank full. My daily driving is 4 trips of 5 miles, 2.5 miles each way, that's rough on any engine and my truck has over 200,000 miles on it. If your vehicle is older and isn't running well give Z-flex a try. I worked wonders for my truck.

GREAT OVER ALL.My GASOLINE MILAGE PER. NOW 39 MPG.WAS 19 MPG

Wont buy again

I like the idea of this, the idea being that the particles are smaller than oil so they in effect seep in the metal of the engine, adding additional protection against wear. The performance improvement they claim is based on friction. less friction engine runs smooth cooler and potentially generates more power, or performance.Our engines get abused, regular maintenance is the key to keeping them running great. todays modern synthetics have proven to go many more miles between changes and have reduced wear and engines really last much longer than they have ever in the past.Adding this to your engine with every oil change will provide a small level of improvement in the wear of the engine, and thats definitely a good thing.

Well I like with the product said it offered. There's no way to tell if it's doing what it said it would do.

This engine oil additive is surprisingly great. I’m not even going to pretend to know anything about cars. I like making my very old car (2000 Toyota Corolla) look and run as good as possible, especially for its age, but when it comes to knowing much about the workings of my car or any other car, I really am not an expert. I can do the basics and that’s about it. While I can’t tell you the ins and outs about how this product works, I can tell you that it DOES work, and it works well! I added this to my car’s oil tank, and since adding it, my car has been running so much more smoothly. The idle of the engine smoothed out and the car sounds and feels better while driving it. I also am getting a bit better gas mileage. I don’t usually find that additives do a great deal, but this one has me sold. Highly recommend.

I put this in my 19-year-old Massey Ferguson tractor. It's a 3 cylinder diesel engine. I really wanted to see if it made it quieter as with older tractors you do have a lot of noise, especially with a diesel. Now I can't say for sure it got quieter but it does sound better and before putting this in the tractor the temperature would always run around 170 degrees. After adding this to the oil the tractor now is running at 164 degrees. I can't believe it dropped the temp down 6 degrees. I was not expecting this to do that.I am buying another one to add to my lawnmower to see how that works.if you are looking for an additive like this for an older motor give this one a try. I don't think you will be disappointed.

I added this to my 2016 Ford. It is hard to tell with 100% confidence, but, it seems like it made the engine run smoother. It appears that my engine starts a little smoother than it did before. I am not sure if the MPG increased so I will not comment on that.
