XADO Tuning Motor Oil Additive - High Mileage Engine Restore Oil Treatment - Atomic Metal Conditioner for Gas, Diesel and LPG Engines - Friction Protectant, Cylinder Compression Restorer, Bottle 7.5oz

I bought magazine "Popular Mechanic" and sow advertising of this product. Then I read about it and decided to buy this product. My dad have Nissan Maxima with 150000 mi and I add this conditioner. After a few minutes the engine start work like new. Whiteout any noise, vibration. When he drive his car it got a lot of power. He was exited and start to tell everybody about it. I recommend everybody who have a car with 75000 mi add this product to keep your engine in good condition.

Good price,prompt delivery, engine runs smoother and quieter.

Only thing you need to remember - to wormed up before to add it to your engine.

Fast delivery and well worth the money.. I recently purchased a 2000 Nissan frontier 4cyl with over 100,000 and notice it lacks power in some places so this would be a perfect opportunity to put this product to the test again, I used the same product on my 2000 4runner 4cyl with over 150,000 miles which woke it up from sleeping. So after adding xado tuning atomic metal additive to my existing engine oil I left my truck running for 20mins to get the motor nice and hot before driving it around. I drove it around for 50miles and notice a big difference in power and acceleration, also the engine is running a lot smoother

Appears to perform very well in my 33 year old 5-speed manual transmission vehicle, mixed with 10-40 semi-synthetic oil. I can't verify it's overall longevity, since my vehicle is classified and tagged as antique. It doesn't travel long distances, but the engine revs nicely going through the gears.

The product came on time, and at a good price. With using a product like this, you have no way to prove the company's claims. My hope that it does work as described. If the price it's worth the peace of mind. I with continue to use it after a couple of oil changes, and then determine if it's worth it. So I do plan on purchasing the product the next time I perform an oil change.

I can't open up the engine and see inside, but the car runs very smooth and continues to get great gas mileage while I use the XADO products.

Motor seems quieter with increase in millage. 06 Cadillac DHS
