Hi
I've used it in a number of cars over the years and can honestly say that it has done absolutely no harm whatsover to any of the engines (ditto the gearbox version.)
At the same time I can honestly say that it doesn't seem to have made the slightest improvement to mpg, performance or longevity either!

All I've heard about oil additives from lubrication specialists is - don't use anything to upgrade the oil! Oil is build from mixture of substances and it shoul be balanced to get the best lubrication effect- it's the main job of Oil producer all the years. Any next additives can get the lubrication characteristics worse.
I'm working in SKF and we don't support any of these things.

My opinion is that if these additives did any good, one of the big oil companies would have incorporated them into one of their products and sold it for a bit extra. e.g. there would be "Mobil 1 Plus" or some such, marketed as a premium version of Mobil 1.
But insn't that exactly what they do? Each manufacturer brings out a new grade of oil (e.g. magantec) that is probably based on their old oil with some tweeks and additives. I've never seen an ingredients list on an oil so it is very difficult to know what is in there.

While I have heard the the Slick50 oil treatment is not good, has anyone heard of the Slick 50 Fuel System treatment. apparently 400ml goes into the fuel tank with 55litres of petrol. Apparently it's good for Petrol and Diesel, also N/A and Turbo.
Too scared to try it in my car...

True, but the standard ingredients are known. The different oils differ largely in the proportions of those ingredients. As far as I know, no engine oil on the market includes PTFE, the active ingredient in Slick 50. Dupont, the inventor of PTFE who market it as "Teflon" came to the conclusion that it was not an effective additive in engine oils and tried to refuse to sell it to oil additive manufactirers. After a court case they had to do a U-turn on that but instead issued a statement to teh effect that PTFE was not an effective engine oil additive.
Also, as far as I know, no engine oil includes any of the other solid friction reducers such as molybdenum disulphate.
Many of the liquid additives are in common use in engine oils, so why increase the concentration of them? Is the theory that "If some's good, more's better and far too much is just about right"?
The Saab handbooks (well, my 9000 handbooks anyway) explicitly state that they so not recommend using any additives with the oil.
See this article for some interesting reading about Slick 50 and other additives and for some links to other interesting articles.
For me, the bottom line is that I want to see the evidence before I add something Saab doesn't recommend and that I don't have the expertise to judge for myself.
I use to use Stop Smoke in my elderly 9000T when it started to smoke and it did help cut it down. I also put Molyslip gearbox additive in the box at about 120,000 miles. I parted company with the car at 174,000 and it was still running well. I can't say it did any harm apart from the extra cost nor can I say that there was much improvement apart from a reducing from the smoking turbo. I now run my GM900T on straight Mobil 1.

[/qb][/b][/quote]All true, and I have no way of knowing that there are any additives in there. But I do wonder if some of components are just too expensive and would cut into the manufacturers margins or make them prohibitively expensive and so make them uncompetetive. You might be prepared, for example, to add £10 worth of a fuel injector cleaner to your petrol but would you pay that much more for a petrol that had fuel injector cleaners in it.
I wasn't (and am not) trying to stand up for additives. But I do wonder if some genuine ones might be out there but that car manufacturers can not test everything with their cars, and it may not be in their interests to have them last forever anyway.

STP now there's a short word, I use fuel injector cleaning, with a full petrol tank once a month, it seems to help on fuel eco, and should help to keep the injectors fresh, I used to use OIL treatment in the old type on ICE, yesrs ago, always seemd to help oil pressure.
Have never thought of adding to my 9000, not sure what it could do to the turbo.

Very very occasionally I put some RedX directly into the inlet manifold and the rest into a full tank, smokes like a good un for a wee bit and then runs a lot lot better, have used STP oil treatment, also when I have been a long way from home;
this was explained to me as a product that will reinvigorate the detergent properties of oil between changes, have used both products in the same way on all of my cars, my brother does the same on his cars and bikes, my 2.3T is on 126k and his 2.0T is on 190k with no adverse effect
