There has been a lot of stories around about the benefits of octane boosters. It is the cheap ones that don't work. You need to read the fine print. With the cheaper ones you only get around a 0.5 octane increase. This Nulon product, (make sure it is the Pro Strength one), gives real octane increase numbers. In my case with using 98RON fuel to begin with it goes up by 3 units going to 101RON. I know this product works as I did a direct comparison. Drove the car without the Nulon Pro Strength and under load I could clearly hear the pinking, stopped the car added that recommended amount of Nulon Pro Strength and drove a bit to make sure the booster was well mixed and reached the engine, then again drove under load with no pinking. Also, with the Nulon Pro Strength the engine would run on when switched off. With Nulon Pro Strength there is no running on. It does work and works extremely well.Read full review

I have a worked Datsun Fairlady which uses 98 octane and is prone to a little pre ignition sometimes when turning off motor. A bottle of this every few tanks fixes this and makes for smoother running. Better than alternative octane boosters available too.

Put this in my Ford Focus ST Turbo along with 55 litres of 91 RON petrol and the car runs like it's on 98 RON ,so yes I would recommend this product if you want to bump up the RON in your fuel. 500 ml is supposed to do 60 litres of fuel but I went conservative and mixed it with 55 litres with superb results.

Great prouduct especially if you used 91 fuel and your car needs 95 or 98 Increases octane and stops pinging within a few kms of driving.
