Repco have a clearance for an older version of the product that offers 6 years / 350,000km endurance, but when I collected mine I actually got the newer 8 years / 500,000 endurance version of the produc, which retails for around $64. You might be lucky and get the new formula, but for 350,000km endurance, even the clearance item is good value.
Note this is a concentrate product of 5L which makes 10L once you add soft water.
