Nulon

Appears to do what it says on the bottle – I noticed a marked difference in the performance fo my 170,000 Km 3.0Lt Turbo Diesel Hilux after using this product. I used the method where the… Read more

entire bottle is added to 40 Litres of fuel. I will be using this product again after another 5000Km. This product apeared to imrpove the performance of the vehicel more than any other product I've used. And I've used a few. Comes on spesh at Supercheap for about $20.00 & represents good value for what it does.

I was a bit sceptical, but needed to stop the smoke (wife not happy) - wow this stuff is fantastic – I used this on my Jeep GC 2002 V8 with nearly 200,000km. It started billowing smoke out of the exhaust while idling ( sign of valve stem seal leak)… Read more

especially after I used a slightly thinner engine oil that was on special. My wife was not happy. I was desperate and decided to try this stuff, despite being skeptical. As such I decided to only put in a small amount (125 ml of the 500 ml bottle) just to test it to see if it makes any difference. It totally stopped the smoke. WOW, I still find it hard to believe how well this worked. I’m a mechanical engineer, and do most of the maintenance on our cars; with absolutely no affiliations with NULON, or any one else. In fact I was going to try another brand, but my local AutoOne store only carried this product. Anyway, it immediately stopped pouring out copious amounts of smoke. I’m a bit flabbergasted as I’m not into oil additives and never have been for many decades. Totally took me by surprise. This stuff totally exceeded my expectations by a mile. This is the most amazing product I’ve come across in many decades of motoring.

This ATF makes false claims regarding suitability. Using it, means risking damage to your transmission/expensive car – I wasted a lot of time and money buying this Nulon ATF. I lived apparently in a fairytale-world, where I thought that if a supplier writes onto his… Read more

product that it is suitable for something, that the consumer-protection-agencies would have checked that, so that I could rely on it - but sadly not. I bought 40L of Nulon ATF (for 2 cars), and after just having filled it into the car, I have found out in very long Jaguar Forum discussions, that this ATF could potentially damage my transmission, and that Nulon's claims that their ATF could be used ilo. "Lifeguard 6" are definitely wrong. I wrote all those technical details to Nulon with a complaint regarding the unsuitability of their ATF to Nulon about 1 week ago – but no reply at all. If they were convinced that their product is legit, they would have defended their product – but they know exactly…

And here are the facts and details:

The Jaguar S-Type 2002 - 2008 has the transmission ZF 6hp26. ZF recommends to use Lifeguard 6 (on page 4): https://aftermarket.zf.com/remotemedia/lol-lubricants/lol-en/lol-te-ml-11-en.pdf

And this is the MSDS (Material safety data sheet) for Lifeguard 6:

https://aftermarket.zf.com/remotemedia/master-content/zf-services-portal/oils-data-sheets/pc-1/lifeguardfluid-6/msds-zf-lifeguardfluid-6-aus-20190219.pdf

One of the more important parameters is the kinematic viscosity at 40 and at 100°C (call it KV40 / KV100): it's KV40 = 26.8 / KV100 = 5.6 and this is 100% in line with Shell spec m-1375.4, and this ATF has been designed very specifically by ZF Friedrichshafen for this transmission.

Now Nulon comes along and they claim that their ATF can substitute 50 (!) other ATFs. See that claim at: https://www.nulon.com.au/products/auto-trans-fluid/automatic-transmission-fluids/full-synthetic-multi-vehicle-automatic-transmission-fluid

As I did not know better, before having been enlightened at the Jaguar Forum, I believed that!

That link also says Nulon ATF KV40 = 33.4 / KV100 = 7. Interestingly, the Nulon MSDS claims something else altogether: Page 4 in the link below: KV40 = 37.

https://www.nulon.com.au/images/products/files/sds/full-synthetic-multi-vehicle-automatic-transmission-fluid_sds.pdf

This shows, that Nulon does not even have too much of an idea themselves, what the KV of their own product is - so there is not much point in paying any attention to Nulon's claims regarding suitability of their product...

So Nulon's ATF is way too "thick", or to put it technically: high viscosity fluids move sluggishly and resist deformation, which means using Nulon ilo. Lifeguard 6 heats up the transmission excessively - with a great potential to do damage.

Nulon claims there as well, that their ATF can replace both: Lifeguard 5 and 6. You can see the KV of Lifeguard 6 above, and the for Lifeguard 5 it is: KV40 = 37. Lifeguard 5 and 6 are obviously totally different ATFs, designed to totally different specifications! If Nulon claims that their ATF can replace both of them, you have proof (again) that everything they claim has no meaning at all.

Obviously, Nulon risks damage to the cars of the customers. This is highly dangerous, too. And in the world, where I live in, I also cannot see, how that can be legal.

This stuff may have changed my mind – Being a mechanic I never believed in a "mechanic in a bottle fix" we purchased a bobcat 3 years ago with a suspected blown head gasket. It would run… Read more

fine but get hot and push water out all the time. Today I put a bottle of Nulon radiator and engine block stop leak in ran it for 15 mins, it went straight up to just under hot where it always runs. Turned it off. 1 hr later jumped in worked it for over 2 hrs and it never went over half on temp gauge and didn't push a drop of water out!! This stuff may have changed my mind....
