I used to use Molyslip in all our engines... having first used it on a Rally event... in an RS2000 Mk1 and had it prove it's worth... we cracked the sump (smashed the sumpguard to bits on a rock) , lost nearly all the oil in a mile or so and still had some 15 miles of special stage to go....
got to the end of stage, Service crew replaced Sump , Sump-guard and oil, and a new tin of molyslip/.
Zero observable damage to engine, Finished the Event (4 more stages) and the next 2 events before scheduled rebuild.... rebuild showed no more obvious wear in bearings and the like than was normal for the engine...
Molyslip proved it's worth......
I've been using slick 50 in the Meega, actually because it came as part of a package deal with some injector cleaner... which i use.
some say mine is one of the nicest/smoothest sounding V6 meegas they've worked on recently .
whether that's got ANYTHING to do with Slick50, I have no idea...

I used to use Molycote many years ago, though I don’t do it any more (who wants BLACK oil from day one?
)
I think Molycote is a great product and certainly does what it says on the box i.e. reduces friction and cling to the metal bits etc. The point about Slik50 and similar PTFE-based products is that they claim to better Molycote, but the worry was that (a) the PTFE products in an engine environment do not actually contribute to friction reduction, and (b) that PTFE bits floating in the oil can be damaging by clogging filters etc.
The issue is still controversial, and DuPont (who invented Teflon, the commercial name for PTFE) initially refused to sell Teflon to automotive additive manufacturers, but was taken to court and forced to supply the product, so they issued a statement saying that ‘there is no proof that using Teflon in an engine has any advantages’. To be honest their reasons for not wanting to supply Teflon were probably more to do with commercial reasons than them worrying about the well-being of you engine, but the fact still remains that the use of Teflon in engines was and still is disowned by DuPont.
I don’t think the product is needed in modern engines that can rack-up six figures mileage easily without it. In fact, if you follow this website you will see that it is almost unheard off for cars to have internal engine wear damage – cars either get scrapped with good engines because of other faults, or they suffer from internal engine damage due to tensioner failure. But worn engines, excessive oil consumption, etc – very very rare.
As for driving without oil, as soon as the oil drops both your oil pressure light and the low oil level warning on the MID will come up – unless you are in a Rally or race the thing to do is switch off the engine asap. I don’t think I would want to continue driving without oil even if I did have some additive in the engin. In my opinion anyone continuing to drive on the road without oil thinking ‘I have Molycote’ or ‘I have Slik50’ should have his head examined…
As for running an engine without oil, surprisingly it does not suffer an immediate damage… I once serviced a 1.8 Astra and after draining the oil I started the car, forgetting that it has no oil… when I saw the oil pressure light I realised what I have done and switched the engine off – it probably ran for a minute or so without oil. I had the car for several years after that with no problem. Obviously running engines without oil is not recommended, but the point is that if you loose all your oil and switch the engine off as soon as the oil pressure light comes up, you will probably still be OK and not cause any long term damage.
So in short I don’t see the point anyway, and the fact that the product is controversial is even more of a reason not to use it.
