Schucks has it on sale for $12.  Is it worth using?  My vette has 53K orginal miles.  Thanks

 Use the search button above 0 type in oil additives - C3 general discussions - you will see alot written - looks like it works according to members -Good Luck

On Ken's (kstyer) recommendation I've put it in "The Toy", "BIGBRRD", and "The SilverBuckboard" ('70 Vette, '78 TransAm, & '01 F-150) on their last oil changes.  Too early to tell on any outcome. Norsky38893.8689236111

Hey Big Al.  Go over that again with me how I do a search.  I tried under General Discussion-typed in Oil Additives, but none were found.

And Norsky, keep me advised to what you think......Thanks!!!

Here's the links for your help.

I've done some research on this stuff and the best description that I can print is it is nothing more than 'Snake Oil'

See link http://skepdic.com/slick50

Don't bother! Use a good grade of motor oil and you'll be fine. The synthetics like Mobil 1 or something similar are even better. I've raced my '68 for over 30 years without EVER having an oiling problem.

 

My sugestion would to use Royal Purple Engine oil and (if so desired)Purple Ice Radiator coolant additive. Your vette will run cooler and the oil protects quite well,is synthetic and has been proven to gain a few Horsepower. If your engine leaks any oil then you might want to think about using it because it is a litle pricey and you dont want to spread it all over the highway let alone your car. Excellent stuff though. Best oil in my opinion.
FYI. I have used Slick 50 in my 86 Turbo T-bird which always ran hot especialy at red lights. My overtemp cooling fans would always come on but with the Slick 50 they rarely did. Ok stuff. Will have to add it at all oil changes.custom7638913.0161342593

I agree with Custom 76 - use Royal Purple and forget the additives. I put it in my '69 small block and while working on it a mechanic put a stethoscope all over the engine and said he couldn't hear a thing clicking, clacking or knocking!

I learned about it from a fellow who has a Corvette garage and builds racing engines. He showed me some bearings lubed with regular oil and some lubed with RP - no comparison. Best reccomendation  have gotten on motor oil!

I do not like most oil additives.  Slick 50 is a metal treatment.

Here is real world testing.

My brother's 1985 S10 pickup with 30,000 miles.  Driven the same way, by the same driver on the same route daily. Purchased new.

EVERY dime and drop of fuel, oil etc that ever went into this truck from day one was documented.  My brother is like that.

I did a 30,000 mile service on the truck, then he put an additional 1,000 miles to see that mileage etc was the same.  It was.

I did a complete engine analysis, then added Slick 50.  The truck was driven 1000 miles, and fuel etc tracked.  Then another complete engine analysis.

The results.  After Slick 50 this truck picked up 2 mpg.  Compression stayed the same.  Cranking amps required to start a fully warmed up engine before Slick 50 was 130 amps.  Afterwards it only required 87 amps.  This is a direct result of reduced friction.  Engine temp dropped slightly, about 10 degrees average.

These numbers continued until 110,000 miles, when a head gasket let go, dropped antifreeze into the crankcase, and ruined the bearings with antifreeze.

At 105,000 miles I did another check.  The mileage was STILL the same as it was after adding Slick 50.  Compression was within 5 psi on all cylinders.  It still required 87 amps to crank the engine. Engine temp was consistant.

I have tested it in several other cars as well, but not that long term.  Results were all similar.

It works.

Many other additives I have tested have done nothing, or created problems.  Some are good as a bandaid for worn engines, but are not helpfull, or even harmfull to a good engine.

After the work I have done to the engine in my Vette breaks in well, it will get Slick 50, as do all of my other vehicles.

Some of the bad press is due to teflon formulas used in earlier versions of similar treatments.  They did not stay in suspension and caused clogging of oil passages and components.  Silck 50 fixed that problem, and it does not happen.

It works by filling the holes in the rough surface of metal with teflon to create a smooth surface, allowing the oil to work better.  Machined metal is a rough surface, even it it feels smooth to the touch.  The teflon also allows less friction when operated without oil, such as start up conditions, where most engine wear takes place.

I do not endorse products lightly.  I only recommend what I know to be good.  There are many I know to be bad, or at least not helpfull.  I never just test one car, or make one test before I make my decision. I do not believe published testing, and do not use those test as part of my testing and results.  I need to see it in person.

AND it does NOT replace the need for quality motor oil.  It helps oil, it does not replace it or do it's job.
