Holden cruze 2011 had low boost pressure and when accelerating from 1k rpm to 2k would often stutter and loose power. Also was getting limp home mode as dpf was clogged. I ran 2 bottles of the nulon diesel cleaner through and it made a huge difference! Car isn't stuttering anymore. Dpf passive regen went from 3 times on a full tank to 1. Fuel economy when from 7.9 to 6.9 per 100kms. Acceleration is linear and smooth and now have confidence over taking people as before when I accelerated my car would stutter and loose power.This product made a huge difference and will Def buy every 10km

Fantastic product. Will be including this in my 10,000km service routine.Having a car with over 220,000kms and only being 5 years old I am always looking at ways to maximise the life of the engine. One bottle into my 80L diesel tank has really done the car some good.

Have a 2007 audi q7 which had a sluggish 3.0l diesel engine, guessed the injectors were pretty gummed up.Put the bottle in with 45L of fuel and immediately felt more power (octane boosters) but then 120km later and a few of hard accelerations to clear the injectors the check engine light went off and now am getting much better fuel economy 9-10l/100k as opposed to 12+Great value when on special at $20
With many fuel and injector cleaning products on the market and having been using another brand for 4 years on my Pajero with 350,000 on the injectors I decided to give the Nulon Pro Strength a go with pleasing results.It took half a tank before I noticed any change.. Injectors were quieter, economy went from 11 litres per 100k to 9.6. Pretty happy with that.
This is the first time I’ve used this brand of product As I usually use liquid Molly.I pored it in just before filling the tank up and it honestly did a great job of quieting that diesel injector clatter but.. while the bottle states a large interval for the next treatment it hasn’t seamed to hold much truth to that.So far I’ve used a good 3 quarters of a tank so around 52.5 litres of diesel. And that typical common rail clatter is back alreadyI can’t really see any improvement in fuel economy or any significant results overall.honestly I have had better longer term results with liquid Molly and both products are around the same price.
I have a 2006 Nissan Navara D22 ZD30 turbo D/Cab and do a lot of country trips to South East of W.A. with around 230,000 kms on the clock.I have owned this vehicle since December 2015 and have clocked up around 70,000 kms on it.I dropped all the oils on it and refilled with Nulon products and 3 months after buying it, took a trip to Queensland and back to Perth - It ran fantastic and purred like a kitten all the way.I have regularly run the Nulon Diesel Injector Cleaner 300ml regularly through the fuel tank but I still felt that the motor was lacking overtaking power even though I have done the recommended Mods to the motor.I decided to put a bottle of this Nulon-Pro Strength Diesel system Extreme Cleaner 500ml and before 1/2 a tank of diesel< I noticed the ... MoreI have a 2006 Nissan Navara D22 ZD30 turbo D/Cab and do a lot of country trips to South East of W.A. with around 230,000 kms on the clock.I have owned this vehicle since December 2015 and have clocked up around 70,000 kms on it.I dropped all the oils on it and refilled with Nulon products and 3 months after buying it, took a trip to Queensland and back to Perth - It ran fantastic and purred like a kitten all the way.I have regularly run the Nulon Diesel Injector Cleaner 300ml regularly through the fuel tank but I still felt that the motor was lacking overtaking power even though I have done the recommended Mods to the motor.I decided to put a bottle of this Nulon-Pro Strength Diesel system Extreme Cleaner 500ml and before 1/2 a tank of diesel< I noticed the engine was performing and responding 100% better than before.It has usually taken 3/4 of a tank to get to my destination and another 3/4 tank to return to Perth - under 1/2 a tank of diesel each way, a distance of 450 kms each way.I am heading away again this weekend and will be adding the Nulon - Pro Strength Diesel Turbo Cleaner - 500ml to the fuel system and can't wait to see if there is a further improvement.I recommend running these products through your Diesel Fuel system and see if it works for you.I highly recommend ALL of the Nulon products - I have used them on all my vehicles past and present and have prevented potentially costly mechanical breakdowns occurring by using Nulon products.Use Nulon products with confidence!
I have a '08 Mazda BT50 that decided to throw a check engine light not long after hitting 300,000Kms. Came back to a P2008 code. After cleaning out the intake system and MAF manually light was persistent.Found this product, was sceptical at first, but for less than $30 why not give it a try. It worked. After just over 1/2 a tank the light is off and staying off.Turbo cleaner is next...
Excellent product. The cleaner is best added when the tank is low to allow better penetration into the system. I bought a car knowing it had been sitting on the lot for some time, so I bought the diesel cleaner as i had heard good things. Fuel economy and engine performance has improved greatly. Mileage has gone from about 500km per tank, to at least 600km. Average litres per tank has reduced from 12.1L/100km to 10.4L/100km. I believe this will be a one-off jump because the system has been sufficiently cleaned that the next time the additive will just be preventative maintenance. But there's no denying the Nulon cleaner did its job. Highly recommend.
My car is one year old and only has 15,000km on the clock, but mostly suburban driving. Noticed that the fuel economy wasn't as good as other people have claimed to get in the same car. I poured a bottle of this stuff in the tank and filled it up. I've only gone through 1/4 of a tank so far, but already I've noticed an improvement in fuel efficiency from 11.5L/100km to 10L/100km on the dash readout, with no change in driving style.
