Slick 50

[Doods]

Been working on the engines this weekend getting all the service stuff done.
I was also planning on getting the oil change done and have Slick 50 ready to add. Never added it to the boat engine before but always use it in my vehicle engines.
Any one else use Slick 50 in the boat engine,.
Good and bad feedback welcom

Do you really think it makes much of a difference??

I've never used it apart from many many years ago when on my first car the engine was playing up badly.

We removed the engine, stripped it and completely rebuilt it including re-grinding all the valves etc.

As we re-assembled each section we smeared Slick 50 on every component and then when we filled the engine with oil we used the rest of the Slick 50 in it.

Yes the engine ran beautifully compared to before, but I suspect the work we did was at least 99.9% of that improvement!

A memory I have regarding slick 50 was back in my rally days. I rebuilt the engine and as ontheplane did I smeared everything with slick50. At the end of a rally a stone got wedged between the sumpguard and sump and punctured the sump. I drove two miles to the end of the stage and 10 miles home with no oil (Very carefully) I expected the crank etc to be in mush. When the engine was stripped the crank was still in good condition and the engine gave many miles of faultless service afterwards.
I use it in a ski boat and who knows if it is or isn't a good idea but the engine hasnt blown up.

On my last boat (Volvo AQAD 41) one year I made the mistake in using cheap engine oil (to spec but unbranded), I used 1 pints of oil in the first 400 nm,both engines the same, in the past I had not needed to add oil during the season.

I added slick 50 in an attempt to upgrade the cheap oil.

I didnt use any more oil that season ( 1600 nm).

I have not used cheap oil since but I can confirm slick 50 reduced oil consumption that season.

I used it on my Reliant Scimitar's 3 litre lump, it made a remarkably difference, I'd just had the engine rebuilt and when I came to 500 mls I changed the oil, then adding the S50 as per instructions. immediately it was poured into the running engine, the revs increased by 500 at tickover and the engine sounded much quieter and sweeter running. The engine ran faultlessly for the next 70,000 mls in my ownership and is still going today. The fuel consumption also markedly decreased. All in all a success, though I have heard that others on the forum have had different results.

I have also dropped several litres of the stuff into my boats Ford Lehman 6L 6cyl non turbo lump 5 years ago. no adverse results, a slight increase in revs on tickover, fuel consumption is hard to guage but it did sound a bit sweeter.

I have usedit for many years now in both diesel and petrol engines and think it fantastic - it may not be quite as good today as it was when it first came out but its stil excellent - I have lost all engine oil on 2 engines, 1 a Peugeot 504 on the motorway when the oil filter came loose,, it was rattling like hell as I limped off the M5 I got to a garage and bought 5ltr oil the guy at the garage said 'you will need more than oil after listening to that' a few miles later the rattling stopped and that engine did at least another 10,000 miles before being sold. I had exactly the same with my ex-wives MGB when its oil cooler burst and she drove it home with the oil light on - only 5 miles but you would have thought she had a very poor band behind her banging the drums of hell! Again it worked! - Since then I have used it in all my plant - fork lifts, gennys, crane, compressors etc. and now my boat, I think its great.

PTFE in suspension ... coats everything. Invalidates many warranties. Has been known to cause blockages in engines. Widely available previously, few revealing trade articles etc. and it dissapears from many shelves. Isn't it strange that the full page mag ads have gone ... no longer put fwd as THE magic fluid etc.

Trade always laughs when some obscure Test facility is quoted as having tested a product and the report is so fantastic that you wonder why Heaven didn't incorporate it into everyday life !! /forums/images/graemlins/cool.gif

I have no idea if it works or not, I only mention the above based on historical data over some years .... /forums/images/graemlins/wink.gif

Well
Looks a mixed bag of opinions. I have never had a problem with any of the vehicles I have put it in, and I cant see why it will be any different in a marine engine and no one has been specific about it being taboo on marine applications.
Think I will give it a go in one engine and keep a close eye on it over the next month. If all goes well then I will try it in the other lump.
Thanks for the feed back guys

Re: Slick 50 and this will interest those who wish to read ..

Legal Action Federal Trade Commision ref. Slick 50

Interesting reading that they were actually cited for their claims ..... read on ... now we know why it suddenly lost its big adverts etc.

Re: Slick 50 ... even more coming up on the web !

I'm having a field day here ... slick 50 test report ... entered into Google really blows it away !!

Try this for a read : Testing Oil additives incl. Slick 50

Does not surprise me at all.

Re: Slick 50 ... even more coming up on the web !

Wow
After reading all of that it looks like the only point they can make is that Slick 50 comes in a bottle.
Any one want to buy 2 x 500ml of Slick 50 ?

Re: Slick 50 ...

Now I don't have anything personal against any of these wonder fluids - I've never used them and never tested them in a lab.
The papers I linked to above are as far as I can tell genuine, but who knows on the web ? Only comment I can make is that the last link - the txt quotes some pretty hefty labs in the testing of these additives. Unlike eg Slick 50 and others who are reluctant to say who where and what.

I'm always suspicious of claims and also personal observations of " I had more power ... revs went up ... started easier etc." without actual proper conducted figures. Many a time I feel a certain amount of psychological "improvement" and not wishing to feel money wasted comes into it and you feel there's an improvement.
It's like I always feel my car drives better after I come out of the car-wash ... why I don't know but it just seems that way. Maybe it's because it see's a car-wash maybe 1 time a year !

Re: Slick 50 ...

Well, this IS interesting............. I've put it in two engines, the first was a Citroen CX2400 with 80k on the clock, 2k later it blew a top hose and I had to drive it 2 miles home thru London rush hour traffic.........repaired hose and engine lasted another 2 years...... tough engine maybe? the other is my Honda CBX550 1983 vintage bought 10 years old with 26k on the clock now done 78k...............thing is, these engines self destruct cam chain assembly every 8k and big ends fairly comprehensively at about 50k. The camchain assembly was replaced by Tony Galea (remember him) at 31k and its still working SILENTLY and all I get at tickover is a clutch rattle....go figure, I don't know if it's the Slick 50 or the way I treat it, still good for top speed of 116mph (GPS measured) 26 years old this May. I dunno. /forums/images/graemlins/grin.gif

Re: Slick 50 ...

I used to put slick 50 in all my car engines back in the 80s and 90s, and always saw an improvement in oil pressure, smoothness and fuel consumption...and if I ever get the engine rebuilt in my boat, I'm going to put it in that too-I'll have those bottles doods!

I'm amazed that anyone would think these snake oils would be taken seriously by anyone

That is literally a reprint of my second link given earlier ... where various NAMED labs give results and verdicts.

Basically you go with what you consider best. I can get Russian version of Slick 50 ( it's identical as far as we can tell) for about 2$ a litre bottle. We do not use it.

Good and bad feedback welcome

The Slick 50 formula went through a change in 1983. There's an explanation of what happened here:
