Helps engines perform as intended#
The higher octane of Vortex 95 and Vortex 98 Premium petrol can offer improved performance in many newer and turbocharged vehicles.
Many modern engines demand high octane fuel to deliver optimum performance. Direct injection and turbocharged engines are common across many vehicle car manufacturers, who recommend high octane fuels to obtain optimal performance.
The octane rating is a standard measure of a fuel’s resistance to pre-ignition or knocking.
The engine control systems in many modern vehicles can adjust the engine’s ignition timing to take advantage of higher octane fuels and produce more power and torque. Some engines will not perform optimally with lower octane fuels.
Vortex 98 and Vortex 95 are both high octane premium fuels, suitable for petrol engine vehicles.
#We tested the performance benefit of Vortex 98 using a standard Holden Commodore 3.6 litre V6 engine at an independent Australian testing facility. The engine was run on regular unleaded 91 RON fuel and on Vortex 98. The results showed, on average, 4% more power and torque compared to regular unleaded fuel. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
90% less engine nasties*
The special cleaning agent in New Vortex Premium fuels attacks the deposits that form on intake valves and fuel injectors. These deposits can adversely impact the combustion of the fuel, and can lead to a loss of performance.
The cleaning agent in Vortex removes these deposits by breaking them away from the surface of the valves and the injectors. It also leaves a protective layer over these surfaces to prevent the build-up of performance-robbing deposits. Ongoing use of New Vortex Premium fuels removes existing deposits and protects the fuel delivery system from the formation of new deposits.
The cleaning agent is available in Vortex 98, Vortex 95 and Vortex Diesel.
*The cleaning performance of New Vortex Premium Petrols were tested using the industry standard engine test ASTM D6201. Designed to measure a fuel’s ability to protect against intake valve deposits, this tests uses a 2.3L four-cylinder engine operated on a dynamometer over a 100-hour test cycle. Intake valves are weighed before and after the test to determine the weight of deposits formed during the cycle. Vortex Premium petrols were found to generate 90% fewer deposits than a regular, unadditised petrol. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
We tested New Vortex Premium Diesel’s cleaning performance using the industry standard engine test CEC-F-98-A-08 (DW-10). This test uses a high pressure common rail engine, and measures the loss of power due to deposit formation over a 32-hour cycle using a regular, unadditised diesel. The loss of power was significant, clearly indicating that performance robbing deposits had formed on the injectors. After switching to new Vortex Premium Diesel, this loss of power was completely restored over the test cycle. This means that the cleaning agent effectively removed deposits as the engine was running and returned the performance to the same level as clean injectors. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
26% better protection against wear compared to unadditised petrol*
Engines have many moving parts that slide against each other. The piston inside a petrol engine vehicle is moving up and down the cylinder wall thousands of times per minute when the vehicle is running. This metal-on-metal movement can cause friction and lead to wear along the cylinder wall.
The friction reducer in New Vortex Premium petrols provides additional lubrication during engine operation by coating the cylinder wall. This can lead to less friction and protection against wear.
*New Vortex Premium petrols were tested using the industry standard High Frequency Reciprocating Rig (HFFR) laboratory test, IP 450. In this test, a metal disc, submerged in the test fuel, was subjected to constant rubbing with a metal ball over a specified time period. The size of the wear scar on the disc is measured at the conclusion of the test. New Vortex Premium petrols containing a friction reducer showed a 26% smaller wear scar versus unadditised petrols. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
Prevents the formation of abrasive rust particles that could cause engine wear^
If water and other fine particles are present in fuel it can lead to the formation of rust. This can result in abrasive particles entering the fuel stream and potentially cause wear of engine parts.
New Vortex Premium fuels all contain a rust inhibitor that coats the internal surfaces of the fuel system and prevents the formation of rust.
^We tested the rust inhibition properties of New Vortex Premium fuels using the industry standard laboratory test ASTM D665A. In this test, a polished steel rod is immersed in a mixture of petrol and distilled water at 38oC for four hours. In this test, new Vortex Premium fuels were confirmed to completely protect against the formation of rust under conditions that would otherwise cause substantial rust to form. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
Ensures a cleaner and faster fill that forms no stable foam^^
Regular diesel can produce foam during filling, which can prevent the tank from being fully filled. The foam builds up inside the fuel tank and the filler neck, and triggers the fuel nozzle stop before the tank is filled to capacity. To fill the tank to capacity, you have to wait for the foam level to collapse and then restart filling. The foam level rises again and triggers the nozzle stop. The process is repeated – sometimes many times.
This foam can also lead to diesel splashing back from the vehicle filler during refuelling, resulting in a messy fill experience.
New Vortex Premium Diesel avoids all the hassle and mess by eliminating most of the foam so you can fill up faster and with no mess.
^^The foam inhibitor in New Vortex Diesel produces no stable foam, helping to achieve a cleaner and faster fill. How do we know this? We tested New Vortex Diesel against regular, unadditised diesel using the industry standard laboratory test NFM-07-075. Fuel was injected under pressure into a measuring cylinder, with the amount of foam formed and the time required for the foam to collapse measured. The test results showed that the foam inhibitor in New Vortex Diesel prevents the formation of stable foam. Individual results may vary by car, driving and environmental conditions and driving style, amongst other factors.
