Engine Oil Additive/Protection For Motor/Additive For Wear Protection & Rebuilding Of Worn Metal Surfaces/Metal Conditioner With Revitalizant 1 Stage Maximum (Up To 5qt Of Oil Capacity)

I have a 1993 Jeep XJ. The engine (like many 4.0's) had a tick that was starting to get pretty loud. Tried many of the typical fixes (different oil, filter, additives, cleaners, etc.) with no real improvement. After doing a bit of research and looking at some of the other reviews, I decided to give this a try rather than tear the engine apart. I didn't notice an immediate improvement like some people mentioned, but after driving it for a couple of weeks, I've noticed significant improvement. The volume of the ticking sound has significantly decreased to the point where it's hardly noticeable. I don't know about more power or efficiency, but if it helps the engine run better and longer, that a definite win. I'm optimistic with the results, definitely glad I gave this a try!

I've been using this miracle product for 20 years, and my engine refuses to age. Unlike me! 😆 I pour XADO in, and the engine purrs like a happy cat. 🔹 What I've noticed over the years: ✔ The engine runs smoother, like it just came back from a spa day. ✔ The oil stays clean longer—I don't know what XADO does, but they should probably open a dry-cleaning business. ✔ Fuel consumption decreases, though not enough to buy myself a yacht, unfortunately. 🔹 Cons? ❌ Now all my friends come to me for car advice. ❌ The engine feels so good it might start demanding premium gas and a massage. If you want to extend your engine's life, don't wait! XADO is like the elixir of youth, but for cars. 🏎🔥

I bot this fir my 98 durango 5.2 v8 got it with 209,??? Miles on it and it ran fine it just smoked a lil bit cuz fryed rings from prevo ownerand ran ruff somedays and fine on others and factory max rpm waz 5250 but it would over rev and back fire right at 4500 not even redline zoned and couldnt peel out or powerstomp it even on small ass 235/75r15 tires (28in tall) so yea i firgurd i would give this $63 work of god in a bottle a try b4 i dumped out $1000 for a performace rebuild kit... so this how i did it- dumped all old oil flushed it till all clean oil came out with a quick cranking of the engine couple times to allow the moving oarts get cleaned and made shure all old dirty gas smelling oil waz gone and then refilled all but 1quart with cheap walmart hi milage mystery brand oil with a new 15kmile filter then started it and let it warm up wile ispent the next 15min hassle of trying to get the dam bottle to shake and mix p.s does not happen in 35deg weather so i ran in side ran the hot water on full blast on the can till i couldnt hold the can cuz it waz to hot grabbed a towel and it shook and mixed freely like milk that waz so much easyer!

Wonderful product. I drive a 14 year old Towncar with a bit over 200K miles. I was just starting to have a bit of valve clatter (not bad), but, I could tell my compression wasn't as good as it once had been. Wow!! this made a difference. It wasn't bad before but it is great now. Great product-so glad I used it. My son's Towncar is 16 years old with around 250K miles and it made an even bigger difference in his car. Increased his gas mileage almost back to manufacturer spec (took a couple of months for that to happen, but, it did). His mileage had dropped to around 17mpg and now it is back up around 21ish. WELL worth the price. Update 062614-My Towncar now has 238,000 miles on it and is now 15 years old-it recently developed some issues with fouling out plug #8 repeatedly. I used this product a second time and it has 1) increased the pick up and overall pep of my car, 2) increased my mileage back to a combined average of 22-23 miles per gallon, 3)it also seems to have slowed the oil leak onto plug #8 considerably. I'm not sure yet if it stopped the oil leak into the cylinder, but, I do know it has improved it significantly, at least. It is a wonderful product based on the results I have obtained. It may be that I have to repeat the use of it occasionally, but, it is WELL worth it based on the results I have gotten both times I have used it!!

I have used this a few times with very good results. We used this in a very worn out 20hp lawn tractor engine that was blowing a tremendous amount of oil out the exhaust.This engine also had some lower crankshaft/connecting rod noise.Added about a 3rd of this bottle to the engine and ran it for a few minutes. Engine stopped smoking almost instantly and it started to run much smoother.This engine ran great for about 3 weeks after treatment then it blew up after mowing the lawn.Lower end bearing failure. So the Xado did its job sealing the cylinder and piston rings but the wear on the lower end of this engine was too bad for the Xado to help.I was very impressed by this experiment.This product seems to work very well to re-seal piston rings /cylinders.Works faster under heat-friction and pressure from what I have experienced.

I'M A believer in this product.. Made my AUDI run smooth as butter..And it has more power when I STEP DOWN ON IT.. IT feels like a NEW RIDE. Give it about 2 days to work itself into the motor. You won't be disappointed.

BRZ（走行距離:3万km）に投入したところ、エンジンからのノイズが減り、回転がスムースになってアクセルレスポンスも良くなりました。

I have been using XADO Engine Oil Additive for several years across multiple vehicles, and the results have been consistently outstanding. My engines were starting to show signs of wear, with reduced compression and increased oil consumption. After applying this additive, the improvement was noticeable almost immediately. The metal-ceramic layer it forms on worn surfaces works wonders, making my engines run smoother, quieter, and more powerful. I have also seen a significant drop in fuel consumption. It is easy to use, works with all engine types, and doesn't interfere with the oil system. I highly recommend this product for anyone looking to protect and revitalize their engines.

I've used it but can't really tell if it helped or not

Buen aditivo. Lleva una parte más densa, en forma de tiras redondas, cortas, como de cera, que es de mal gestionar, para verterlo el el motor. Lo usé en un Renault 21 2 litros inyección, con 330.000 kms. Ahora el motor va más suave y silencioso. El aceite se ensucia menos, o tarda más.

Instantly quietened the engine upon starting, good product
