I never used them. If you use good synth oil additives ... are not needed...
Snake oil stuff mostly...

Never used them and never will because the r&d went into the engine without needing them so it works without them.

It is a touchy subject this one because some people swear by them and others dont.

Only one i use is Proma MBL8. Was recommended by a few mechs. I don't currently use it though mainly because its expensive and a bit of hassle to get in Launceston.
Good thing about MBL is it is universal. Can go in an engine as well in some gear boxes and open diffs. MBL will quieten a noisy diff and help the bearings last longer.

Although the engines don't 'need' them, doesn't mean they can't work better with them. Liqui-moly is a German company which has been around for over 60yrs and has the runs on the board with their Mos2 friction reducing additive in particular. It was originally used by fighter pilots to allow them to land their plane if they had a direct hit on the oil tank, resulting in a complete oil loss.

I've read up a lot about their products and the R&D that goes into them, and they have a lot of credibility over a long period of time. I currently use around five of their products regularly and find them great. All made in Germany as well, if that counts for anything

I would try them if I had an engine problem like a stuck lifter. If it's running well I wouldn't bother throwing stuff in my engine just for fun. I hear lifter free is good stuff for cleaning the engine tho.

Just use decent oil and change it regularly.

Well this perhaps:

The inference was that ZB commodores are somewhat sub-par?..all I'm asking for is your reasoning behind that?

You might have taken the inference to mean something it didn't?
Personally when I am shopping for things like tools and I want quality I will often hunt down something made in Germany or Japan since made in Australia no longer exists.... Have you used a German Wiha screwdriver? Fantastic.

Thats why i said its a touchy subject.
There are many companies that make all sorts of claims about a product and whether they are true or not it comes down to the customers that stand by the product whether it works or not.

In my opinion it comes down to the longevity of an engine that uses an additive and one that does not use it and whether there is any difference over a certain amount of kms or years.
The test must be repeatable over and over with the same outcome showing that the additives had a positive effect towards extending the life of the engine regardless of the claims made on the bottle and the testing would need to be done by an independent party.

As for german well volkswagen is german and they did the whole dieselgate thing by faking emissions testing procedures and selling millions of cars that scientists say will cause alot of premature deaths so the germans like anyone have no problem making false claims about a product for profit.

I read it as a throwaway humorous play on their lack of popularity, rather than any serious comment on quality. :)

As for oil additives ... I just buy my oil with the desirable additives already in it.
The mechanic I go to is a very cluey guy & has had enough experience with motorsport that when he recommends a specialist to rebuild a head based on both industry reputation & personal experience, I trust that head specialist. And said head specialist listed all these reasons that just using Penrite or Nulon in the right grade was going to be at least as good for my engine as putting extra additives in the oil ... sorry I can’t remember the reasons, but as a result I’ve just been buying Penrite (would also buy Nulon but the independent local car-parts guy stocks Penrite).

Your not wrong there @Forg
Penrite seems to be taking over the shelves everywhere at the moment. It's even becoming difficult to find Valvoline now as they are being squeezed out of Super cheap by the looks of it.
And Penrite is good stuff but I prefer Valvoline engine oil and Nulon Full Syn MV ATF in the VE so they starting to make my life difficult!

I didn't say that. You did. I was only quoting you from post 5.
I was only trying to be funny.

Liqui-Moly MoS2 for me. Been using it since 2005 in all my cars.
- Can quieten engines down a little bit, some more than others.
- Improved fuel consumption claims are so minimal it's impossible to measure.
- It's preventative maintenance, providing long term engine wear protection under extremes (like daily cold starts and hard driving). That's what I'm interested in.
- Some oil manufacturers still use it in their additive packages, for the above reasons.
- It's origins are military, like much of the cool stuff in this world (eg: synthetic oils and Ethernet protocol/the Interwebs)

I did heaps of research into use of molybdenum disulfide (MoS2) in engines to understand if it's a snake oil or not. There's LOT's of conflicting opinion out there... but opinion can only be used as a guide. I looked into facts and got comfortable that the science behind Mos2 stacked up.

Decided that Liqui-Moly MoS2 was the product I'd use, because:
(a) it was TÜV Rheinland certified (means it was independently certified in Germany to verify that it DOES do what it's designed to do), and
(b) it was readily available at car parts stores and fairly cheap.

Used it in a Mazda CX-9 3.7l V6 for 200,000km from new with 10,000km oil changes and it never missed a beat. Pushed it hard with lots of towing, beach & dune soft sand use and daily stop/start school, shop, errand runs... so it was exposed to extreme service conditions. When I sold it, the motor was still strong. Guy who bought it independently commented that it was the strongest of the CX-9 engines he'd test driven.
I use MoS2 with a quality synthetic oil.
