Almost immediately after I poured the content in my engine, and started driving the car, I could tell the engine is not working as hard. 1000 km later and the car is using a liter less of fuel per 100km. Engine works smoother. I can not tell or see what happens internally inside the engine, but it is happy!

Having used the Xado addative I have found that I have a smoother running engine, I rebuilt my Subaru engine (on 102000 miles) and it has only done as of now 1050 miles but I can feel its allready smoother, when the 1500 miles is up I can honestly say it will have improved my engines preformance considerably, a great product in my opinion.
