I would stay away from any thing that had slick 50 written on it. Even though quakerstate owns it who is owned by Shelloil

 

Google slick 50, was lawsuits and quilty of false advertisement.

Im not going to give you any BS. Im my 2 experiences of using it in slowly failing transmissions. It has worked. The shifts got a little better and it stopped slipping.

 

The trans shop that put it in recommended it to me and said I wouldnt promise you anything but it might work for 1 day or a couple years. Of course if you flush out your trans, it wont work out. Add it just the way it is, dont do any servicing to your transmission. A couple bucks for a bottle is worth a chance.

 

 

 

 

 

EDIT, the only thing Ive found about any lawsuit against Slick 5o trans treatment, is 1 post on a nissan Forum pretty much repeating what youve just said, Don. The lawsuit is only about their engine additive

I couldn't believe it either! Anybody remember the Slick 50 booths at the state fairs in the early 80's? LOL. My grandfather used that crap in 2 cars in like 1982/83, a citation, and a malibu (both low mileage back then)...the citation's cam failed, the dealer wouldn't fix it under warranty because they claimed he had an oil related failure (maintenance item). He didn't believe it was the slick 50 and continued to use it in the malibu, it began to burn oil profusely and the dealer claimed it was due to "cold weather starts, and neglect" LOL crazy, he owned a Honda/Stihl chain saw shop and was so meticulous with his maintenance...

There is some stuff that is only marketed/sold thru reputable trans shops. I would trust my local knowledgeable shop for a product for this application. Not something that I can buy at Wally World.

Man, this'll open a pandora's box, but I guess I should justofy my inflammatory statement.... :D

 

This is JUST MY OPINION.....

 

there are many good shell products, mostly lubricants (Rotella Motor Oil, etc) that I have had personal experiences with. I wasn't making a BLANKET statement... well, OK I was.... :D

 

Had a Fire Department Mechanic that used Rotella Oils exclusively on Detroit Diesel engines for YEARS with excellent results.

 

Now, for the gasolines, this is all from my personal experiences, and I have heard similiar anecdotes for years:

 

Shell gasolines contain additives that have made my engines make noises I have NEVER heard before. Back in the 80s, when I was a "wet-behind-the-ears, not fully cooked" college student, I had a VW Golf GTI, one of the first models sold in the US. Put Shell SU2000 fuel (remeber THAT?) in it ONCE, pinged so bad I couldn't believe it. Went back to Mobil (pre Exxon-Mobil back then) and it all went away.

 

I still have a copy of a letter that VW sent to owners, back then, stating that they would NOT cover warranty repairs on the FI system if it could be verified that owners had used Shell fuel products. It was on corporate VW letter head. The reason stated, was, that shell gasolines had additives that would, eventually, attack the elastomers in the FI system, and it would fail. Also stated that the additives for increased octane "were not consistent with the longevity of its engines". I waited patiently for Shell to file a lawsuit against VW which never came... That told me a lot....

 

I have heard MANY experiences with Shell gasolines in tuned engines. In fact, Diablosport recommends numerous "quality" gasolines... Shell isn't among them. I also know that many other tuners do the same.

 

IT's the "where there's a mouse there are probably mice" thing. Never touched Shell fuels again. Numerous Diablo tuned vehicles have reported bad operability which was, eventually, traced back to fuel. In most occurences, the Shell brand was involved... and the problems ceased upon using other fuels.

 

So, I guess it's up to everyone to make up their own minds.... mine is.

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
