It was touted some 40 years ago as a formulation that would protect your engine. So, could not sleep last night and instead of sheep, or sugar plums, for some reason, thoughts of Slick 50 popped into my head. I remember it making a big splash and lots of my friends bought into the stuff. I would have, but it was expensive and I was not rolling in cash. Was it good I saved my $$? Quaker State Subsidiaries Settle FTC Charges Against Slick 50 | Federal Trade Commission I guess it is still around in differing formulations, as well as many other brands that tout treatments. Think I will stick to Kirkland synthetic engine oil.
i was at a trade show where a guy was demonstrating an engine with slick 50 and no oil. iirc, it was made out of some clear material so you could see the inside working, or a window type thing. it was impressive, but might have just been a dream.
I'm old, I remember Slick-50, I may have "treated" a car or two back in the day when cars were rarely kept for much longer than 100K miles. Yes, there are several products that tout the benefits of PTFE/teflon chemical formulations. There are several products that tout molybdenum/moly additives as well that have similar claims of coating/protecting metal surfaces and decreasing friction beyond what you get from motor oil, whether it is synthetic, conventional, etc.
PTFE is a forever chemical, so you cannot even get decent dental floss anymore. It is slick but it probably does not stick well on metal surfaces. Which means what? It gets stuck on your cat converter or what? .
I was reasonably new in the trade when this first hit the shelves in Australia. Slick 50, Wynns oil treatment and ProMar oil treatment were put to the test on the Timken roller test machine along with 3 well know high cost oils. Each oil on it'd own was tested, Mobil 1 wasn't available back then and it would have been interesting to test it along side the others. The only oil that passed the load shear test where 50ftlb was applied on a torque arm holding the Timken roller against the inner bearing case, was Penrite 20w/50, I won't name the other oils, but they were expensive yet the roller friction welded to the inner race within a min or so, even after being run in the oil bath for 10 mins at no load to allow a good coating of both parts. If enough pressure was applied, the motor would load up significantly, even with the Penrite oil. New, the oil that failed the test the worst, was again tested with each additive and allowed the 10 mins to condition the metal surfaces ..... Slick 50 did no better than the straight oil, Wynns and ProMar passed the test and accepted loads of 100ftlb without seizing. The oil cup was removed and the test between the 3 additives was repeated, the Slick 50 seized very quickly, the Wynns lasted for quite a while under 100ftlb load, but the motor amps went up after a short period, the ProMar lasted 10 mins without a noticeable increase in amps after the intial load was applied, but both rollers had a section the shape of the inner bearing cone worn into them .... more a visual difference between the Wynns and Promar, the micrometer was hard to read any difference at the lowest point. The catch with the ProMar was not to use in an engine before it had been run in, oil it used oil, found that one out to my own expense after using their grease when fitting the pistons and rings into the bore, 1ltr per 1,000kms oil consumption and remained the same for 20,000kms, but used it in the drag race engines, oil was cheap insurance under that sort of punishment. The other catch was oil changes every 2,000kms along with the filter in older engines, until the oil stayed clean on the dip stick. You most certainly didn't used either in very high milage engines, it was only the junk built up that kept them sealed ... Another disaster story with Slick 50, another service centre put it in a doctors Ferrari, it didn't take long before it lost oil pressure at idle and low rpm. The story went, the helical groove cut around the floating oil pressure relief valve was filled in to the point insufficient oil could bypass and the light spring pressure on this relief valve wasn't enough to stop the oil bypass ..... no idea if that was fact or fiction, but the story goes that the Slick 50 people paid the Ferrari mechanics to fully rebuild the engine ..... no idea if that was fact or fiction either ..... So, an actual test to prove what worked and what was air powered ...... T1 Terry
