Hi thought I would post this on the STR site as well as the XJ forum. Anyone use Xado Engine treatment in there STR? This stuff is supposed to keep your cars engine better than new. Saw this reviewed on Trucks on Sunday Morning and they said its really good, Top Gear Magazine in the UK also said it was good. Bit nervous about trying it, anything that's keeps the Engine running well is great by me but have no experience of additives. You guys over here Mod more than the XJ owners so thought I would ask.

 

Most experts advise car owners to stay away from engine treatments. Changing your oil and oil filter on a reasonable schedule (every 5,000 to 7,500 miles) is all you need to do. I believe the Jaguar owners manuals also recommend that no oil additives be used....

What are you attempting to accomplish?

 

Despite employing every method known to man over more than a century of research, no additive has ever been shown to fix something that's not broken.

Our Jag engines live long and healthy lives by doing standard maintenance using standard materials, no additive is going to improve upon that.

There is a LACK of any credible evidence that this particular product does anything at all. My trusty steed has this observation to offer:

 

As was said above. No need. Spend your money on maintenance instead.
.

I take that as a no, no one has used it!

 

You can also take it as 'not going to use it' as well.

 

Why use it? The engines last a long time IF maintained. That stuff is not required at all.

 

Ok so lets look at this, I look after my cars with the best oils (castrol in my opinion) and spare no money to keep my cars running as we'll as possible, I do not work for any automotive company and are not looking for any silver bullet and I don't listen to my mate down the pub who has an opinion on every thing! New technologies are being developed all the time and anything that can make a car last longer with no ill effects is good right but to find out you need to hear from owners who know there cars and have used products if this stuff works or not other wise you are just taking the word of the company or the opinion of owners who have not used the product, both these opinions are flawed. Someone once said the world was round and not flat and to prove it he went and found out. Information and factual results work in my book that's all I was asking.

 

How would an ordinary owner be able to tell properly i.e. factually whether it was any good? Face it, they would only be likely to be able to tell if it was VERY extreme, like blew the engine up. Not likely to be extreme so not likely any useful data even if people used it.

It's your car, stick the stuff in if you like. I think you'll be the first to fall for it.

 

Interesting website.

The TUV certificate of effectiveness strikes me as odd - I've asked TUV if they issued it.
The tribological paper (from Proceedings of the Serbian Tribology Society...)they quote is not concerned directly with their product.
The Chinese paper
http://www.xado.co.uk/images/tribolo...-engineers.pdf
is really rather interesting and appears genuine.
It cites a 6% silicate addition to lubricating oil producing a layer of 'hard carbon' on cylinder liners. No silicate is present in the layer and they postulate it acts as a catalyst causing the lubricating oil to break down and deposit this layer.
I'd think putting ceramic nano particles into an engine counts as sabotage - I'd like to see what TUV say.

 

Thanks Steve this is what I am looking for, I found an article on the Alpha Romeo forum from a garage owner who has no contact with Xado but independently tested the product with compression tests, oil consumption and engine behavior over a period of months. His findings which where documented very well indeed found no difference in the engines from before to after, but he did say that the Engines did run slightly smoother but this could of been somewhat of a placebo effect and should not be counted. So it looks like Xado has no benefits so in conclusion I will not bother.

 

And there's the good news and the bad all rolled into one - you'll never find anyone who can provide proof that these products work.

Today's engines typically go from cradle to grave without issue, given even a half a**ed attempt at standard maintenance. When's the last time anyone heard of an engine packing it in due to lubrication issues? Despite the small % of owners that truly abuse their cars, they seem to survive nonethless. Without using the overused superlative of being 'bulletproof', engine durability is just not a concern any more.

This is obviously very good news for owners but is also good news for the snake oil manufacturers. They are well aware of this inherent reliability and can package any ineffective and benign mixture of 'miracles' they want knowing full well that the engines would last virtually forever with or without them.

For all we know, this Xado 6% of silicate added to the oil may actually reduce engine life marginally- but it would take hundreds of thousands of miles to find out one way or the other. The car would have had umpteen oil changes by then, plus changing ownership possibly more than once. Who would know or remember that some miracle juice was added to the oil many years earlier or make the link that this might be why the engine died?

As mentioned above, you can't fix something that's not broken.

 

I think there may be something there but, as you know, clever people latch onto a scientific fact (maybe of dubious provenance) then somehow integrate this into their product.
If I hear from TUV I'll post their reply here.

 

Interesting reply from TUV
the product Gel-Revitalizant for Gasoline Engines of the company XADO-Technology Ltd. was tested by us.
The approval for using our test mark has expired. The product is no longer monitored by TÜV Thüringen.
A test report in German was issued by us. A test report in English does not exist.

Kind regards

In other words TUV didn't write the report.

 

So some testing has been done but it looks like nothing concrete that can be looked into to make any real decision. Thanks for contacting TUV Steve.
