Tried this in a 40 year old fuel injection car. Car was standing for over 10 years so looking to clean out the system. Appears to be doing the job. May need a second dose.

My car was running a little rough and I’d already looked into plugs and vacuum leaks. The fuel injectors must have been dirty as this fixed the problem.

I have a 2020 Hyundai i30 N Line Premium. 1.6ltr turbo. Running 91 all the times is fine but I felt the performance wasn't there. Emptied the tank and used a bottle of this with 55 litres of 98 Premium. Driving I noticed sharper gear changes in performance mode and better acceleration with idling better. I will now use this every 4th tank.
It does its job. It helped me gain an extra 50kms from the tank of fuel. Could have been better but 50kms still is a bonus
I was having issues with an OTS tune on my car. Basically our 98 octane fuel in Australia isn’t as good as America’s 93 AKI or Europe’s 98 octane so I needed to supplement my fuel with a slightly higher octane to correct some timing issues. This product made absolutely no difference to the cars timing meaning the octane booster made no difference to the 98 pump fuel.So really this product is useless you are in the country where it’s difficult to get anything better than 91octane and your car requires 95 to run properly, or just simply fill up with 98 octane.However in my testing I found Nulon Pro-Strength (The one in the silver aluminium bottle) actually did make a big difference.

Half a bottle of the pro-strength in my tank fixed all my timing issues which means it actually does raise the octane level of 98 octane.I hope this review helps people choose the right product for their application. Basically if you want to use this product, see if you can find 98 pump fuel as the pump fuel is still better than the “boost and clean” product. But if you’re already using 98 fuel and need a bit more, use the Pro-strength product.
I have used this product a few times over the last 8 years, probably once a year. It works really well even in a 12 year old Camry Altise that is parked away in a garage for couple of weeks no use. Yet this seems to keep the fuel nice and juicy when I drive the next time. Fill on last ten litres of fuel and drive the car on highway for an hour or two (I use it before interstate travels) and you will feel the difference. Car feels quiet, smooth acceleration, fuel economy in Sydney CBD is really good getting 8-9L a tank and Toyota service are quite impressed despite long periods of no use. I use the Pro Strength Extreme Fuel Clean as well, so maybe we are onto a winner. Hope this helps. Regards
Good product, well priced, helps increase octaine level in High Compression Engine. Regularly use this product, no concerns recommending
Put a bottle of this in and topped up my tank before a long trip. I found throttle response improved slightly, and the boost in my Turbo Charged 2L was a little more prominent.I'm not sure though if it cleaned anything as I only poured this product through as a preventative maintenance and not to treat a symptom. 4 tankfuls later after the treatment, the car feels exactly the same in smoothness for idling and driving as before the treatment.I only noticed the Octane Boost effect during treatment.
I bought this a month ago, used it in a Toyota Echo that was rattling & pinging consistantly.poured into a quarter of a tank and ran for 50 km,s before filling. The vehicle has stopped rattling & now runs well on 91 fuel.well done good product
