No lynch mob here, but I would not reward manufacturers for
intentional fraud. The court depositions made it pretty clear that the indivuals involved knew it did not work, and could cause engine damage under certain conditions.
The absolute worst damage was caused by those that believed that you could actually drive the car to a service station after the oil light came on when using Slick 50. They, of course lost their engines. Sadly, many came forward with this outcome.
It was interesting to see who actually tested the stuff.
GM
Ford
Briggs and Stratton: They were lured in because Slick 50 recommended the use of their motors in "sideshow demonstrations"
wherein the oil was drained out and then the motor was restarted and ran for a while. Interestingly, Briggs found that the motors would run longer without Slick 50 then with it (after the crankcase was drained out) and the damage was more severe with Slick 50. With it, both the piston and rod bearing seized up, without it only one did - I no longer remember which. (sorry, this is clearly a research failure)
The US ARMY vehicle command: Tested for the same reason as Briggs, if a motor could run even a couple of minutes longer after the pan was blown off it could be very valuable.
Again, no luck
Then, there was the long "epa cycle"tests actually conducted by Slick 50. They actually showed that ordinary energy conserving motor oil gave better mileage than oil with Slick 50 in it.
Like Mr. Madoff, those who stood to profit knew they were clipping the customer.
