Highway - Oil Additive for Car Engine - High-Mileage Motor Revitalizant Restore Treatment - for Gasoline, Diesel and LPG Engines, Worn Metal Parts Repair - Atomic Metal Conditioner (Bottle 7.5oz)

I am a big Xado fan after using this product and the auto trans product. They work like they say they do. My engine runs smoother and has more power after using this engine treatment. I will use the more $$$ one for my new car as they have a different app for that. My trans no longer sticks in gear where I have to manually override, all fixed.

Works like it said!! Brought my over 200k Ford Edge 3.5 engine back to life again!! Will definitely purchase again.

The engine began to run quieter and smoother.

All these additives are purchased on your trust in their claims. This one seems pretty good. My results have shown a decrease in oil consumption and clean oil longer. I notice a darkening about 5000 miles . I like that it is less expensive than other high profile additives like Zmax.

👍👍👍

great thing! I'm happy with it!

So I followed instructions and let my car sit overnight. Next morning I honestly couldn't believe it ran smoother. It definitely is saving on gas mileage after driving for a few hours. Give it a try.

This is the third or fourth bottle I've purchased over the past few years, adding one with every oil change when due. I've driven many miles these past few years and this product has taken great care of my engine. Technically, one can is supposed to protect the engine for many thousands of miles but I appreciate the added power and quietness of my engine when I add it to the oil after the oil change. Great product.
