This is one of the best proved additives out there. I've been using specifically XADO 1 once to an old Iveco Daily 2.3 engine and the difference was significant. Increase on power ,less fuel consumption and most important that van I've sold on 450 000 miles and the engine was still good . Yes , it is a bit expensive , but you can use only once per 100 000 miles . The difference i believe each vehicle is different but from my experience after 400-600 miles can see significant power increase.

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.
