This product transformed my engine
I own a 2003 Ford expedition with 290,000 miles on it. When I would get on the highway and try to drive it more than 75 mph the check engine light would start flashing due to low compression and low power. I used some of this product and drove it for about 1000 miles and I believe it completely restored compression and power in my engine like it just came out of the factory. I can now drive 100 mph no problem. It can pick up speed with half the RPMs as before. Incredible product I am a firm believer in the XADO products. Thank you for saving my vehicle.

Waste of time and money
Used it in my Cummins 6CT 8.3L diesel, which had become a little sluggish with age. I added one bottle and drove 1,000 miles. Didn't seem to do much, so per directions, I ordered a second bottle for a second treatment. Changed the oil and the oil filter, then added the 2nd bottle. At first it seemed to help somewhat as my oil pressure increased a bit. However, after 250 miles the engine seems to have blown the head gasket (bubbles in my coolant tank). Before XADO, engine was burning no oil at all. After 2nd bottle, I'm down 1 quart of oil within the last 100 miles. Save your money and your engine, and stay away from this stuff.

Works great in my rig.
I have a 2014 Freightliner Cascadia. It has 438k miles on it. With the first tank of fuel I've noticed a 0.5 MPG increase in fuel economy. The engine runs smoother with less vibration. The second tank I'm up to a 0.7 MPG increase over all. Used this product before in an old daily driver and was impressed with the outcome. Thought I'd try it in my rig, and I'm not disappointed. Great product!!!

中古のブルーテックキャンター 14万km 10年落ち に使用 添加走行後3000km 過ぎた辺りから 明らかにエンジン音とパワーが変わりました ただし 開封したときに ゼリー状になっていたため 良く振り 湯煎もして 流動性を高めてから 注入した方がいいと思います
