Yeah mineral oil. Some food coloring appeal, fancy label and box, nice bottle, has to impact the cost but the wallet took the biggest impact - sure glad they don't run all them TV skits like they used to.
Nice gift for those you hate.

OK so it must not be Z for Zinc, or the drug that is top of Google, but is this it:
Snake oil Z max
Never seen it for sale in the EU except on Fleabay.

Say what you want about it, I have personally seen some amazing pistons out of a Lycoming aircraft engine rebuilt at my BIL's shop. Truly clean pistons and rings like a 20k mile car engine in a motor with a couple thousand hours on it! The guy was an old pilot who used it in his planes.

Zmax actually prevailed in their FCC lawsuit, the product does some things very well despite the hoo-hah.

There is no comparison between an aero engine and a modern car one. Different compression ratios, fuel type, injection system and even ignition control. I wonder what the chances are that it was tested in all the different engine types to see if it worked and to check for long term damage to seals and bearings etc. Close to nil is my guess as it takes years and big bucks to test a new lubricant additive.

I haven't used it but they are the only additive I have seen that had to put up or shut up in a court of law and were able to put up enough to validate making their claims.

Good point.
Now that I think about it I did use it once. I never saw any difference in fuel economy or how the car ran so I never bought it again.
Didn't Carroll Shelby endorse it? I think I saw a program where he stated he put in the sump of every car they build.
I may be mistaken though.

This is part of the Z MAX web site I agree with:
Today, the wholesalers, distributors and counter people have to face Chemical Roulette: Engine, radiator and transmission flush products, friction-lowering engine additives, detergent and solvent chemicals that de-carbonize the engine along with fuel tank and injector cleaners; all to aid in better mileage. A lot of so-called problem solving additive products.

When the consumer approaches the automotive chemical isle, vertigo is easily experienced. Whatever sells the best gets front row position. Rarely does the question, does it work, come into play. Does the counter person know the quality of these products? In most cases the answer is, NO.

The counter person rarely knows the facts for 50 different products. Whichever product has the best advertising, the best sales force, the best shelf position, is the winner, regardless of whether or not the product really works.

Today's engine oils are excellent performers. Synthetics and engine oil packages such as GF-4 and now GF-5 API approved categories have almost eliminated the need for the use of aftermarket engine additives.

The rest is classic snake oil advertising!

The exact same problems as a car only WORSE! Carbureted, no injection. Lousy weak ignition system with poor spark intensity. Air cooled with horrific hot spots based on airflow and power demands.

Every piston airplane engine I have seen apart on a bench (my FIL was a helicopter pilot and FAA licensed inspector) has had horrific carbon buildup and tons of coke in the rings and the heads.

With Avblend (Zmax in a different bottle-http://www.avblend.com/faa/faa.html) the difference is almost miraculous. So it does offer some very unique cleaning properties at the least.

The FAA did not approve snake oil, and would not ever do so.

Adam,

Be careful of these products. Check out the FTC's website about this Z- MAX stuff before you buy it.

Read the really long thread started by Johnny. He had been using this stuff in one form or another since the mid 1940s, and it is a widely used aircraft additive with FAA approval.

It is indeed highly refined pharmaceutical grade mineral oil. They do a chemical recombination on it to make the molecules all the same shape and form, and claim it better impregnates into the voids and pores of metals in the engine.

There may be something to that theory, but volitility if really small molecules, and practical assessment of this being a valid effect are highly questionable. They did a bunch of fancy sounding tests, but they dont appear conclusive to me. Still it may be a useful solvent with some lubricity, and aircraft results seem to indicate that it does something...

That depends on how you define snake oil.

The only thing the FAA does is make sure it does NOT HARM the engine. The do not check to see if it benefits the engine.

If I re-bottle SN 5w-30 oil, call it "super double-duper oil", and charge $50 a quart, it can be considered snake oil even though it is regular 5w-30.

You get to call it whatever you want.

I am not a user, but I HAVE seen direct evidence on more than one engine of its efficacy with regards to cleaning pistons and ring packs.

It is no different than group III "synthetic" oil. Highly re-refined mineral oil that behaves very differently than the general public has been taught.

I thought Cadillac was recommending Z-max in an official TSB for carbon removal in their northstar engines.

I will try and find it. I think most people pass it off for snake oil.

Nicholas, I wouldn't assume ZMAX works just because of that. All of the factory fill or service fill fluids are chosen based on the highest bidder...
