Restore in a 4.0 Jeep

It's good to find a product that actually works as advertised. Many 1998 and older Jeep 4.0 L engines have the infamous “four liter knock”. It's usually harmless and sounds worse than someone not familiar would think. Restore is the only product that quells that noise and usually lasts for my oil change intervals. My brother, other family members and our mechanic weren't believers. Adding Restore to a running engine at the end of the oil/filter change proved the product. Within two minutes, the noise faded, evidence they couldn't deny.

Inexpensive and it actually works.!

Simple to use just add to your motor oil after an oil change. It absolutely works, it increased compression and reduced oil consumption to less than one quart in 3000 miles, before I was adding a quart every 1500 miles. It improved the engines responsiveness and restored horsepower and torque. I definitely recommend it. I used this on a 2008 chrysler town and country 3.8 V6 with 179000 miles still running very well, just getting tired, the Restore has definitely extended its life.

It works

I am surprised that this made a noticeable improvement after driving 20-30 miles. Good product for a reasonable price. I've used it in two vehicles and it's made improvements in both. I hope others have similar results!
