This product works extremely well. Since using it in an early Mercedes Sprinter, I have noticed a marked improvement in fuel economy, the engine idles smoother and the fuel is at least partly protected from Algal blooms. In short, it's a perfect companion for the fuel!

This Injection Cleaner really works & it is excellent. While you might need to use it a few times before you see an improvement in your fuel consumption, it sure will happen & you will not be disappointed. I highly recommend it to everyone. C U L8R

Been using this stuff for as long as I have had my much loved work horse, a 1995 Toyota Landcruiser HZJ75. She's has been to the Moon, on the way back and still going strong! I put this in every tank and I get on average 26 MPG (Miles per Gallon) that's better than 11L/100km for around town/city driving. Also running BP Ultimate Diesel ONLY (of course) and the way you drive (but I'm NOT drivin' like Miss Daisy either). Been doing this since 2008!So as the title states... If you aren't using this stuff you are a FOOL!Only flaw is it needs to be in a 1L availability.
I put this in my diesel Ute, which was running a bit rough.& now it’s running better.Yes it does cost more than others, but it treats 300 litres of diesel not just 80 litres of the cheap products
I use Nulon Diesel Cleaner as a precautionary measure in my Turbo Diesel Ford Escape.I always used Diesel Injector Cleaner in my truck that I used for work for over 20 years.
Have used this before as an aid to keeping injectors clean. Not sure how much it helps but the motor runs fine when using.
I have a 2006 Audi A6 3.0L TDI Quattro. This thing is a beast.. or rather was. It's done 210,000km but since 90,000km, it's had this thing where when I drive under 50km/h, the car starts to jerk around and the rev meter goes up and down. I once cleaned out the throttle box and that 'helped' but never resolved the problem. No Audi forum had a solution. Audi forums are full of people with the same issue. Audi experts and mechanics were useless...but one did suggest getting new injectors. I bought the Nulon injector cleaner almost by accident to demonstrate to my son that these formulas are a scam. He urged me to put some into the tank at the parking lot. I couldn't believe it, it had an almost immediate effect that got even better after 100km of driving. The jerking ... MoreI have a 2006 Audi A6 3.0L TDI Quattro. This thing is a beast.. or rather was.

He urged me to put some into the tank at the parking lot. I couldn't believe it, it had an almost immediate effect that got even better after 100km of driving. The jerking is almost completely gone and this brute of a vehicle has power once again. I forgot what a beast this car was... and, it runs nice and smooth... and, quieter again. Seriously, had I only known this a few years earlier, I would have bought it earlier! This stuff definitely is not a scam. It works!
Tried this as suspected a blocked injector with the van. Worked perfect. Bought another for use in our other car. Bit of noticeable extra power when using it too. Does a lot for such a small bottle of liquid.
I bought this some time ago as a potential (rather cheap) solution to intermittent power loss issues and random cut outs resultant from aging fuel injectors. Prior to using Nulon Diesel Injector Cleaner, I would experience frequent cut (2-3 a week) outs whilst driving and generally sluggish acceleration/performance. After pouring in a full bottle before fueling up, there was a noticeable increase in throttle response, performance and I no longer experienced the random cut outs!!!! Awesome product, and highly recommended.
