Advanced XADO Petrol/Diesel Additive Restores Treats Engine Knocks Worn Bearings, up to 5 liter oil

Did a great job

Instantly quietened the engine upon starting, good product

Definitely made a diffrence. Quieter and feels refined.The engineer seems to be alot happier in its self.Not really noticed a MPG diffrence but not really taken any notice as that's not what I was looking for.All in all on a 70,000 mile deisel engine it was definitely worth it.

Good but very expensive

This is an excellent product you can literally hear the engine sound quitening as you run your car after putting it in. My car runs more smoothly too.I am very pleased to say communication with the company was really good after the delivery company lost my parcel, they have sorted it out. Many thanks. I will buy again when needed.

Good

Used it after getting my oil changed (Hyundai i10) and the engine has been more quiet and the car just feels a bit better, totally recommend Xado, awesome brand that sells stuff that actually works

TRIED THIS OVER MY NORMAL MUCH BETTER PERFORMING CERATEC PRODUCT, I THOUGHT I WOULD GIVE XADO A GO ON MY 70000 MILE MEGANE DIESEL, I HAVE TRAVELLED 900 MILES AND IT HAS MADE ABSOLUTELY NO DIFFERENCE EITHER POSITIVE OR NEGATIVE, NO FUEL IMPROVEMENT, NO RUNNING IMPROVEMENT, NO NOISE IMPROVEMENT, CAR DRIVES AND RUNS NO BETTER THAN BEFORE ADDING,SORRY BUT THIS PRODUCT IS IN MY EYE PURE SNAKE OIL, AT BEST IT MIGHT GIVE SOME PEOPLE A PLACEBO EFFECT OR A PEACEFUL SLEEP WITH THE KNOWLEDGE THEY AT LEAST PUT SOMETHING INTO THE CAR HOWEVER IN REALITY NOTHING, ZERO ZILCH, NADA,RIEN, NICHTS, NICHEGO POSITIVE EFFECTS AFTER NEARLY 1000 MILES IS GOOD ENOUGH FOR ME TO RATE THIS PRODUCT AS USELESS RUBBISH.SO WHY BOTHER USING IT? WELL I HAVE ADDED MY NORMAL CERATEC BACK INTO THE CAR AND GOT INSTANT RESULTS AND BETTER MPG, I FOR ONE WILL NO USE XADO EVER AGAIN AS IT GAVE ME NO CONFIDENCE IN THE PRODUCT WHAT SO EVER.AFTER 30 YEARS OF USING AND REPAIRING MY OWN CARS I VOTE THIS PRODUCT AT LEAST AS INEFFECTIVE AND WOULD NOT RECOMMEND IT TO FRIENDS OR FAMILY OR YOU GUYS.IF YOU WANT THE PLACEBO EFFECT, OR JUST HAVE A FALSE SENSE OF SECURITY OR JUST USE IT FOR THE SAKE OF IT THEN GO FOR IT.... I SAW NO HARMFUL EFFECTS OR BENEFIT SO FEEL FREE TO WASTE YOUR MONEY WITH THIS PRODUCT AND IGNORE MY WORDS.---------------UPDATE---------------12000 MILES LATERCERATEC MIXED WITH XADO XA 40210 DID NO HARM BUT DURING THE TIME XADO XA 40210 WAS IN THE CAR OVER THE LAST 12000 MILES I NEVER SAW ANY IMPROVED PERFORMANCE, OR INCREASED MPG OR ANY BENEFIT WHAT SO EVER THAN USING ANY OTHER CHEAPER BRAND OIL ADDITIVE,THIS IS MY 2ND OIL CHANGE (EVERY 5000 TO 6000 MILES) SINCE FIRST PUTTING IN XADO XA 40210 SO I SHOULD IMAGINE ANY TRACE IS NOW WORN AWAY, I DID THINK ABOUT TRYING OTHER XADO PRODUCTS FOR MY DIESEL ENGINE BUT I SIMPLY DONT WANT TO THROW AWAY GOOD MONEY FOR ZERO BENEFIT ESPECIALLY AS THESE ARE NOT CHEAP PRODUCTS COMPARED TO OTHER PRODUCTS ON THE MARKET,I FEEL I GET GOOD RESULTS FROM CERATEC SO THIS TIME I WILL JUST STICK WITH WHAT I KNOW AGAIN, THE MAIN THING IS XADO XA 40210 DID NO OBVIOUS HARM TO MY ENGINE, IN ALL HONESTY I CANT HELP THINKING THIS XADO XA 40210 IS JUST BOG STANDARD THINNED OIL IN A FANCY TIN BOTTLE. I WOULD HAVE GOT EXACTLY THE SAME OUTCOME WITH NO ADDITIVES AT ALL AND JUST USING MY NORMAL HIGH QUALITY ENGINE OIL EVERY 5000 MILESBASICALLY 2 OIL CHANGES 12000 MILES AND MY MIND HAS NOT CHANGED ABOUT XADO XA 40210 IT IS STILL SNAKE OIL IN A FANCY BOTTLE,I ADMIT IT SIMPLY MIGHT BE THE WRONG PRODUCT OR MY EXPECTATIONS WERE TOO HIGH BUT IT DID NOTHING SO HIGH SHOULD I HAVE MY EXPECTATIONS SET TO PRAISE THIS PRODUCT.
