Review: Good - Very good wot
Review: 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.

## Questions & Answers

**Q: Should i use this in a 6.7l ford super duty motor and if so, should i only use half a bottle (13 qt motor)?**
A: Yes you right

**Q: after you put the product in the engine, how many miles is recommended to run, before you change the oil?**
A: Regular oil change intervals

**Q: Can I use every 40 - 45 k miles , not 60 as it says on the box. I have an older engine...**
A: Dear Consumer,

Thank you for the question. You absolutely can use this bottle more frequently. However, we do also suggest you using XADO Highway for Diesel Truck after every oil change to keep your engine fully protected.

Best Regards,
XADO USA
