HOW DOES THE Z5 WORK

The Z5 causes a catalytic reaction in the air before it mixes with the fuel in your engine, resulting in a cleaner, more efficient burn. As a result, your car needs less fuel and produces fewer emissions. See the How the Z5 Fuel Saver Works page for more information or contact us with your questions.

DOES THE Z5 WORK IN DIESEL AS WELL AS PETROL ENGINES?

Yes. Tests have shown excellent results in petrol, diesel, biodiesel, hybrid and LPG engines. As long as there’s a combustion in the engine, there’s a benefit to be gained.

I HAVE TWO AIR FILTERS, DO I NEED A SECOND Z5?

Yes. You should install one Z5 in each filter.

HOW LONG WILL IT LAST?

Ongoing tests have now been running on the Z5 for five years with no degradation in performance.

DO I HAVE TO SERVICE MY Z5?

No. Once you’ve fitted the Z5 Fuel Saver you can forget about it. When you have your car serviced, remind your mechanic not to touch the Z5 with ungloved hands when they replace the air filter: the skin’s natural oils can interfere with the alloy’s catalytic reaction.

WHAT RESULTS CAN I EXPECT FROM MY Z5?

Different vehicles will produce different results. However, we’ve not yet come across any combustion engine which doesn’t see an improvement after the Z5 has been fitted. This includes better fuel economy, lower emissions and improved performance.

You can see other users’ experiences Z5 Fuel Saver Proof’ page.

CAN I TRANSFER THE Z5 TO ANOTHER CAR IF  I SELL MINE?

Yes.  Just take it out and install it in your new car.

HAS THE Z5 BEEN TESTED INDEPENDENTLY?

Yes. The Z5 has been subjected to a series of independent tests in a number of countries. You can see the results on the Z5 Fuel Saver Proof page.

DO I NEED TO RUN THE VEHICLE FOR LONG BEFORE I START SEEING RESULTS?

While the improvements will begin as soon as you fit your Z5, in some more modern cars with fuel monitoring ECUs you might find that it takes a tank or two for the ECU to adjust itself to the Z5. However, you should expect to see improvements in power and emissions almost immediately. We’ve run dyno trials on rolling roads and seen immediate improvements when fitting the Z5 to our test vehicles.
