I head about an additive, developed by NASA, marketed as an engine treatment called Motor Silk. Is it any good?

I'm hearing about an additive that was developed by NASA and is marketed as an engine treatment which can reduce repairs by 85% and increase gas mileage by up to 20%. It's called Motor Silk. It comes in a kit to treat the engine, transmission and fuel system. It is suposed to treat the metal and last for 100K miles.
My local dealers service manager has never heard of it. Have you any knowledge of it, its performance or its honesty in the claims made?

Before you put it into a new car wait until you see a good independent report on it.
Like a previous replier (sorry can't remember name, sometimes can't even remember my own one :-) ) stated, it can be snake oil like we've all seen in the 70's, 80's and so on.
Granted there are products out there that will help treat the metal (usually just a temporary coating sort of like a rust prevention type of deal) but I do not trust these fix all/cure all products. This is just my jaded opinion especially after seeing people come in to have serious repairs done on their vehicles after they used these products to fix a minor repair (can't blame some of the people, they don't have the money (who does) to make costly repairs and rely on these companies that prey on them, it really erks me!).
If you find out anything let us know, I'd be interested in hearing. Good luck

I looked into it (which you could have done, making me suspicious of your question), and it looks like it was originated by a former Nasa employee, not by Nasa. Hard to judge the honesty of claims, at least the discriptions weren't out in left field. No third-party test results were easily viewed, further raising my concern, but I don't know. I'd be surprised if any kind of treatment could increase mileage that much - of course, you said 'by up to 20%", which means from 0-20%. Gotta watch that 'up to'.

I too have looked into it. But by far the information is supplied by someone selling it and I wanted an expert opinion before I put it in my new Subaru
Forester that's still under warrenty. Thanks for the response but not the sarcasum.

Easy, I just think he's skeptical like most of us are.

I'd say skip it as well. I think most folks after the Slick-50 (and similar) claims years ago chalk this up to "snake-oil", but there are a lot of people willing to give stuff like this a try just because it "might" work.

WIthout real independent 3rd party results, I think many folks here (myself included) will want proof (stats, dyno, etc) before dumping money on this type of stuff, or at least to believe it.

As they say, "If it's too good to be true...."

A lot of good advice given, but I'll add my 2 cents.

Several things concern me regarding that product.
One is a test done by Herguth Laboratories. I've used Herguth Lab's analysis' for several years now, along with CAT's SOS analysis. There is a large portion of the analysis that product's site shows from Herguth Labs.

Among the things missing in the analysis that product shows is one specific thing most oil analysis' measure. That would be Boron. Oh wait, that product consists is made with concentrated biodegradable Boron CLS Bond®.
The concern would be that the boron could create an acid in the oil when moisture is present and for those who know a bit of chemistry, they know that boron is very similar to carbon.

They seem to put an emphasis on it's cleaning ability, which boron is a great cleaning agent. But as it's ability to lubricate, I can think of many other things that are far better.


Here is some of their claims and my comments.

  • Reduce friction 80% >>>>Interesting. Even teflon doesn't make that claim.<<<<
  • Reduce wear 90% >>>>So, if you use it, you should be able to get 500K+ miles out of an engine with little wear. See the problem with this claim?<<<<
  • Reduce (energy) fuel usage by 20%+ >>>>Not even gonna comment on this one<<<<
  • 100% anti-corrosive >>>>Look up boron as a chemical<<<<
  • Reduce emissions by 50% >>>>Sure, a lot of times, you can do that just by changing your oil.<<<<
  • Reduce component failure by 70% >>>>If they'd put that on a warranty claim, I'd use it.<<<<
  • A solid and permanent boundary lubricant >>>>Yep, Slick 50 made that claim too<<<<


  • The problem with "independant" reports is that you have to look at the credibility of the place that is dong the report. Then you have to look at the report itself. Is the report complete? What is omitted? Since they use Herguth as a "source", compare the oil analysis that they have on their site, with a sample one on Herguth's website.
    How much is missing and why?

    Would I use it? Nope.
    Would I recommend it? Nope again.
    Do I think it is harmful? No. But I don't see any benefit in it, versus a good synthetic oil.
