Thanks, C.E. By the way, I was googling yesterday, looking for a Timken lubricity tester, and found a link to a video where this (somewhat elementary) took was being used to evaluate several motor oil lubricants and additives. It is worth a quick look. I will try to find it and post it on here.
I have been there before, but at $12 per paper, I didnt go any further.
Especially when you do a little research on the "winner" of that test, Motor Latte.
You can find a number of items which will give spectacular test numbers on this kind of lubricity unit. Whether they do anything at all inside an engine, and whether they promote longer and more trouble free engine life is quite another thing.
I always harp on wanting to see hard data. For something to be of value and interest, it needs to be tested under relevant protocols, over a variety of conditions, and with enough population in the test set to assure that the data is significant.
I have to update my kill file on Mike Hunter frequently. He trolls with unbaited hooks.
The feds didnt say that the product didnt work. They said that Slick 50 was making claims they they could not substantiate. Not false claims, but unsubstantiated claims. There IS a difference.
I have seen no hard data that shows conclusively that Slick 50 does anything worthwhile.
That is not the way I heard it. All the testing that I have read does show that slick 50 reduces engine friction. That means you can get better gas mileage (something like 3% better IIRC). The problem is that all the long term testing done on slick 50 also showed that it reduces engine life. That is a paradox that is not completely understood (there are plenty of theories). Some of the testing showed that using slick 50 can shorten the life of an engine by as much as half. The advertising for slick 50 either implied or directly stated that the reduced friction would result in less wear and therefore longer engine life, but that conclusion was a pure leap of faith that wasn't ever supported by any evidence.

I dont doubt that it might show some friction reduction. It WILL burnish into metal surfaces, of that I am positive. But I have seen no data at this point that would convince me that it is either a good or a bad product.
Quaker state still markets it. Their current claim appears to be:
"reconditions engine parts and gives your engine staying power, keeping your engine performing at it best"
This thread started by raising the question "is an oil pressure problem due to Fram oil filter?". Later on it was revealed the ownwr of the engine was also getting regular slick 50 wallet flushes. But of course that has nothing to do with the oil pressure issue.
