Z Fuel Stations Claim New Fuel Ensures No Carbon Buildup
After inquiring about their new fuel in regard to rotary engines, Z have came out and said (after talking with Mazda) that their new additive "Friction Modifier" will ensure no carbon build up. (See Facebook Link)

I know it won't eliminate carbon buildup, but i thought i should make everyone aware of this
Please discuss!!!!

Facebook text isn't a link, and is the "Z" only available as a station in New Zealand? If so, I will move this to the appropriate subforum. I've never heard of the brand.
Likely the same marketing scheme as Shell's nitrogen enriched thing.

I already made a thread in the Aus/NZ subforum, but since activity there is low and i wanted responses from some of our more knowledgeable members i made a thread here.

Ah, understood.
A tech discussion with some of the chemical experts of the forum would indeed be interesting.
I personally don't buy it. There is going to be carbon from the combustion, so it would mean that their fuel prevents the carbon from sticking to the various surfaces. If that had really been found, it would be rampant among all brands of gas.
easy test would be to buy some, pour a little bit into a glass jar and light that. See if carbon does or does not build up on the interior surface. Not getting smokey, although I suspect that is carbon too, but I've found from past periods that I have had to burn off bad gas from my lawnmower that there will be an accumulation of flaky carbon that will build up along the inside of the upper rim of the glass jar.
I know that it isn't the same environment as a combustion chamber, but it doesn't behave any differently than other gasoline here, then I doubt it would behave any differently in your engine.

I may try your test this weekend and put a vid or pics up

Email from Z fuel
Hi Jack,
Thanks again for getting in touch with us, good to have the chance to discuss fuels a bit further. Dave Jacobson is our Fuels Technical Manager has reviewed again and I have posted a response from him below.
Jack thanks for your comments. We certainly do not deliberately set out to mislead anyone. We have test data that shows that using ZX fuel will reduce the inlet valve deposits in a piston engine. The generally accepted weight of deposits on a valve below which a valve is deemed to be clean is 30 mg. Using ZX the weight of deposits on the valves to kept to <20 mg. So while this isn’t eliminating the deposits according to the vehicle OEMs it is at a level that they deem to be ‘clean’. ie no expected dis-benefit on engine performance.
Understand that the piston engine is different from a rotary engine, but as you can see from the engine data above the ZX additive is effective at removing carbon deposits. This is a function of the detergent additive pack included in the ZX additive.
The deposit build up propensity of an engine will also of course depend on the individual state of tune and age of the engine. An older engine with maybe less effective seals will result in more deposits forming than a newer cleaner engine. The use of the ZX fuel will mean that less deposits will build up (due to the good cleaning properties) but you are right depending on the engine and the conditions there will still be deposits present in the chamber.
We hope the above helps clarify however if not then it may be easier to have a phone conversation on this one, let us know the best number and time to contact you if you are interested in discussing further.
Best regards,
Tim
