Slick 50

[Aussie]

Just wondering if anyone has used Slick 50 in their oil?

Its a teflon based product designed to reduce engine wear.

I've used it on my Mopar with good results. The oil pump never failed so I don't know if the claims of running the engine w/ no oil are founded. But I got it as a prevetion of wear because I did alot of cold starts and short distance driving. I'm not sure how it compares to other synthetics though I've read that some guys get more oil leaks from a particular grade of syn.

Your rings will soon be stuck to the pistons and your engine will start burning lots of oil, especially in air cooled engines, trust me..

IMO, those additives suck. I did oil analisis before and after Slick 50 and the after results had WAY more Alu. in the samples. Then after a few oil changes with out the ***** added the samples were normal again.

[tshih]

dry sump oil cooled engines are not meant for such abuse (adding additives not approved by factory recommendations.). My advice and that of others practical experience is DON'T USE it in your 911!!!

Bull**** snakeoil rubbish. When your engine is in need of rebuilding no amount of additives will replace the worn off metals to make things right again.

If you do a search on google, you'll find many links to goverment cases and class action suits on Slick 50 and other "snake" oils. There is no need for them as long as you use a good oil. I also tested one particular product which will go un-named that was just kerosene with silicon in suspension - I wonder if it would help worn rings seat :-) Just kidding....

I used it once to fix a bearing on an air cylinder, seemed to help, but then I also added a grease nipple.

I also poured the remainder in my car, but didn't see any difference, but a fellow employee swears it improved his mileage by 10% (briefly).

I do recall that I left the *****50 bottle lying around, then tried to pour out the last little bit. It was unbelievably long and stringy, like a big long string of snot, very strange...

Dupont also has gone on record that they don't recommend the use of their teflon as an oil additive. Thought I should add that.

[sammyg2]

DuPont, the maker of teflon strongly states that it should never, never be used as an additive to engine oil.
Slkick 50 is one step above amway and one step below tornado vortex generators.

15 years ago, I used it in my Honda Civic. I religiously charted fuel economy and after Slick 50 my gas mileage DECREASED!

I'd never put any additives in my engine - nearly all manufacturers strictly recommend against them in owner's manuals.

[Porsche_monkey]

Well it does seem fairly thick, so worse mileage shouldn't really be a shock.

Consumer reports did extensive oil testing, religious oil changes with cheap oil was the best bang for the buck. No additives required.

I guess that pretty much sums it up!

The main problem is with PTFE (teflon) as on of the ingredients of *****50. When it is exposed to the by-products of combustion and heat in an internal combustion engine the PTFE starts to seperate and form into 'wax-like flakes'

If you ever wonder if a particular oil additive is any good.............ask someone who works on piston driven air-craft engines. See what they say. You may be suprised.

Like................................man we're losing oil pressure............................better pull over at that cloud, get out and see what's up

[wholberg]

The rationale behind these additives is that a film of lubricant stays on the metal surfaces when the car is turned off, so that when you start the engine metal-to-metal contact is decreased until the oil pressure is up and oil is circulating. In water cooled American cars it can take several seconds to a minute for the oil to get up to pressure and be fully circulating, so this is when "cold start" wear occurs. In my Porsche, I've got full oil pressure in less than 1 second, so cold start wear is minimal.

Although I have not read any scientific rationale for not using Slick50, I would hesitate to do so in a air-cooled engine due to higher internal temperatures. Teflon melts (sort of) at about 250C (482F), and decomposes at 322C (612F). While our air-cooled engines should not see oil temperature that high, it is possible that localized hot spots may get close to these temperatures, and one of the decomposition products of teflon is HF (hydrogen fluoride) a corrosive acid.

Could be a rule to live by!

Yea, that spray on hair was useless!

here is an interesting read

Use a good oil such as Rotella T or Chevron Delo 15w40. There is absolutely no need for additional additives. They are worthless.

after reading the link in my previous post, there is a comment that says that all the engine wear starts at startup and if you warm your car up a bit you can extend the life of your car by 100000 miles. It has to do with ACID? Anyone ever hear of that theory?
