I used this for so long i can remember and I actually did not use it for around 2 years, because someone I know is skeptical about this so I literally told them ok, I'll prove that this thing works.My millage from 360km full tank per week (literally using my car everyday) for straight 2 years from e10 to 98 octane.Deliberation... Well here it is....I bought this month May 2021 and my consumption became lesser which brings down to 270km a week no matter if it is e10 or 98 octane it never came up 270km a week. I use it every 2 or 3 months or 10,000 either way I save up heaps of fuel.Now up to you if you believe me or not.

I used this on my early model fuel injected van which developed rough idling and an intermittent dead spot that servicing didn't fix. Tried this product with unleaded 98. After only a few km's I noticed my idle speed stabalise. No more dancing tacho needle. Also the dead spot has not reoccurred since using this. I've never previously experienced such good results from a fuel additive. Looks like there's a genie in this little silver bottle. Will be using this product more often.

Bought this as my usual fuel system cleaner was out of stock. Put a 1/4 bottle in my motorbike with a full tank of fresh gas and what a difference! Smoother idling, easier start up, throttle is constant and feels like it has boosted power over all. Really happy with this product!

Have noticed the improved performance and acceleration. A different Fuel injector cleaner product was added 2 weeks earlier and noticed hesitation when accelerating hard on a road trip. Added this product [bought on special] then highway driving of 1900km. Smooth acceleration. Unable to confirm any fuel economy reduction. My Toyota 3.5L V6 engine has always idled smoothly and odometer reading is 249K. Overall, I am likely to use this product again, especially for the next interstate road trip.
This product is exactly what it boasts about. I have a Toyota Prius 2010 and the engine had started producing knocking sounds after the car was started early in the morning. I used to put 91 Fuel. I googled to find the reasons and possible cures. Some of the people had given very good reviews about this product. I bought a bottle and added it all to the full tank of 40 litres filled with 98 fuel. After doing 150 kms I started noticing an improvement in knocking sounds. After doing 600 kms, Voila..!!its all gone. The engine is running very smoothly. I m very much pleased with this product and have bought another bottle to put into my other car. I think, as they recommend, this cleaner should regularly be added after every 10000 kms as preventive measures to avoid any ... MoreThis product is exactly what it boasts about.

I shall recommend this product to every person who owns and loves his car.
My car have done about 100km since I put this in a full tank of fuel. I can say it does makes your engine run quieter and smoother, giving you a more responsive acceleration and power. However, not sure about lowering fuel consumption.
I used Nulon on my E series Merc with 200Km on the clock. Despite car being in good condition I did notice a significant improvement in engine smoothness. Have bought a second bottle to double dose the engine (given it’s done 200km without cleaning fuel system) Again noticed an improvement all be it not as noticeable as the first dose. Will defiantly use on a regular basis for here on in.
Nulon another trusted Australian company and I have used several of their products for years.The modern trend to extreme lean burn engines and direct injection brings with it it's own problem and doesn't help with sub standard fuel building up deposits in the injectors and plugs.Nulons Total Fuel System Cleaner used every few tank fuls kep the entire fuel system from tank through to injector nice and clean.My 1998 XJ8 Jaguar has covered 216,000 klm and has never needed to have the injectors cleaned as i use a fuel cleaner on a regular basis.Any car that suffers from a lot of stop starting short trips where the engine never gets a proper clean out exacerbates the problem and needs to have a fuel system cleaner used on a regular basis to keep them problem free ... MoreNulon another trusted Australian company and I have used several of their products for years.The modern trend to extreme lean burn engines and direct injection brings with it it's own problem and doesn't help with sub standard fuel building up deposits in the injectors and plugs.Nulons Total Fuel System Cleaner used every few tank fuls kep the entire fuel system from tank through to injector nice and clean.My 1998 XJ8 Jaguar has covered 216,000 klm and has never needed to have the injectors cleaned as i use a fuel cleaner on a regular basis.Any car that suffers from a lot of stop starting short trips where the engine never gets a proper clean out exacerbates the problem and needs to have a fuel system cleaner used on a regular basis to keep them problem free and running smoothly.
I have a european Turbo car which presented with rough idling - I changed the spark plugs which improved the situation a little and then I decided to get one of these to see if it makes a difference. I was skeptical as I know from the past that these things do not usually make a difference, but after a few days of driving the rough idling disappeared completely. Now I do not know if this is a coincidence or not but I don't think it was.
Engine of my car Toyota Prius was badly knocking since many days. I googled and found good reviews about this product. I used one bottle with one full tank for 98 fuel. After consuming 25% I started noticing change in engine sound while the car was stationary position. After full tank, that sound had gone completely. Car now runs smoother and mileage has increase. I was very happy and have used another bottle just in case there was something leftover to be cleaned. Overall I m happy with this purchase and would recommend to anyone who is experiencing this problem of engine knocking happening when car is started early morning.
