Fuel additive product update — 4 June 2021
Unfortunately, due to impacts of Covid-19 we’re currently experiencing shipping delays for our ZX Premium Unleaded fuel additive product. Customers in the Napier region filling their vehicles with ZX may not receive product with the fuel additive during the period of 4 June 2021 to 21 June 2021. The lack of fuel additive does not impact the octane rating of the fuel you purchase so you are still purchasing quality ZX fuel. We apologise for the inconvenience and will provide updates on availability. Should you have any further questions please contact us on 0800 474 355.
How ZX works
ZX features both a friction modifier and a cleaning additive. The friction modifier helps improve engine efficiency by reducing friction between the cylinder liner and piston rings. The cleaning additive helps remove performance-robbing deposits on the inlet valves, helping improve your car’s responsiveness. Together it helps improve your engine efficiency and overall performance.
