Slick 50
Back in my college days in the early 90s, when I didn't know an alternator from....a non-alternator, Slick 50 was pretty hot stuff. Then they went out bankrupt and got bought by Turtle Wax I think.

I tried a bottle of it one time in a transmission thinking it might help clean up a 170,000 mile unit. Now I know it's not fair to blame slick50 entirely, but that trans has been screwy ever since. I will NEVER EVER EVER use ANY slick50 product again.
Just my experience.

Slick-50 was acquired by Quaker State, then Pennzoil acquired those two, then SOPUS/Shell Oil Products US, acquired those 3, so Shell now owns Slick-50 & is looking for a buyer, you interested????? lol
Lets think some more about products that have solids in them & say on the container, "shake before using". Now if we use such a product in our vehicles, how are we to shake the vehicle up to get those solids remixed, before using the vehicle after an over night, or longer sit????? How do those particles know not so settle out & clog something important up, or not to imbed themselves into clutch friction material & alter its friction properties, or not to get into a really hot area like piston ring lands, melt & cause mischief ect, ect???? I'm not aware of one vehicle mfgr world wide that factory installs, or specifies products like this for scheduled maintenance. Perhaps these kinds of products are best left on the store shelf to gather dust?????

There's all kinds of oil additives, and they are added by the oil companies. Teflon is overrated anyway, give me a good cast iron pan anytime. My rule is simple, if pilots won't put it in their plane, I won't put it in my truck.

Good rule. I kinda go by that too. If it's good enough for a plane or a big rig, it's good enough for me.

You have to watch it. A lot of products out there do more harm than good and are really more for keeping a clunker on the road for a few months until you can get something better.

I think there are a lot of "snake oils" out there, but there are products that will do a whole lot of good. That is where you just have to do your research and figure out what products (if any) are good for your vehicle

Only thing I would use is Rislone. It is a good cleaner, and keeps the engine clean. Been around almost 100 years.

dupont, the inventors of Teflon (the key ingredient in Slick50) is on record not reccomending "Teflon" for use in oil passages of engine.
aside from that...there has always been a suspension problem with oil additives...they wind up at the bottom of the oil caontainer or the bottom of the oil pan.
newer technology use of things like Moly in products like Mobile 1 0W30 racing and 0W50 racing involve particles that suspend in oil very well.

Don't know if Slick does anything at all, but their demo engine at the County Fairs, was the only time I ever saw an operating crankshaft on a running engine, with the oil pan removed, to demo that an engine treated with their product could run without oil. Knowing County Fairs, it might have been a trick, but it was impressive!

The original slick 50 was an add to fresh oil, drive for 20 minutes, then drain and refill the oil. Ideal was what ever particles that did not bind with the metal needed to come out.
however, mean while, dopont, the patten holder for tpfe, or teflon, was on record saying they did not recommend tpfe to be used as an engine oil additive.
there are a lot of oil additive today that are sub 1 micron in size and will bound to metal porous with out clogging oil filters. Ptfe is not one of them.
in the transmission world, there is only 1 transmission additive that claims compliance with oem standards and that's lubeguard. Lubeguard comes in 4 flavors. Silver which is a universal blend that claimed to work in all transmissions. There is a green, black, and a red version. The reversion is the one compatible with recent year ford fluids. The stuff is basically whale fat, which is an excellent metal lubricant .
but if your transmission is worn and your fluid is not red anymore, we all heard the stories of functional transmissions crapping out once you change the fluid...this is because the friction plate particles in the fluid was the only thing keeping the tranny from slipping.
