In my gas motors I always ran slick 50 oil addative does anyone run it in their diesel? Thanks Randy

 

About Slick 50 and the different additives out there.

The basic ingredient is the same in most of these additives: 50 weight engine oil with standard additives. The magic ingredient in Slick 50, Liquid Ring, Matrix, QM1 and T-Plus from K-Mart is Polytetrafluoroethylene. Don't try to pronounce it: call it PTFE. But don't call it Teflon, which is what it is, because that is a registered trademark. Dupont, who invented Teflon, claims that "Teflon is not useful as an ingredient in oil additives or oils used for internal combustion engines." But what do they know? They haven't seen the secret studies done by Petrolon (Slick 50).

PTFE is a solid which is added to engine oil and coats the moving parts of the engine.

However, such solids seem even more inclined to coat non-moving parts, like oil passages and filters. After all, if it can build up under the pressures and friction exerted on a cylinder wall, then it stands to reason it should build up even better in places with low pressures and virtually no friction.

This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, "In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant" (Rau).

In defense of Slick 50, tests done on a Chevy 6 cylinder engine by the University of Utah Engineering Experiment Station found that after treatment with the PTFE additive the test engine's friction was reduced by 13.1 percent, the output horsepower increased from 5.3 percent to 8.1 percent, and fuel economy improved as well. Unfortunately, the same tests concluded that "There was a pressure drop across the oil filter resulting from possible clogging of small passageways." Oil analysis showed that iron contamination doubled after the treatment, indicating that engine wear increased (Rau).

the FTC and Slick 50

In 1997, three subsidiaries of Quaker State Corp. (the makers of Slick 50) settled Federal Trade Commission charges that ads for Quaker State's Slick 50 Engine Treatment were false and unsubstantiated. According to the FTC complaint, claims such as the following made in Slick 50 ads falsely represented that without Slick 50, auto engines generally have little or no protection from wear at start-up and commonly experience premature failure caused by wear:

"Every time you cold start your car without Slick 50 protection, metal grinds against metal in your engine."

"With each turn of the ignition you do unseen damage, because at cold start-up most of the oil is down in the pan. But Slick 50's unique chemistry bonds to engine parts. It reduces wear up to 50% for 50,000 miles."

"What makes Slick 50 Automotive Engine Formula different is an advanced chemical support package designed to bond a specially activated PTFE to the metal in your engine."

In fact, the FTC said, "most automobile engines are adequately protected from wear at start-up when they use motor oil as recommended in the owner's manual. Moreover, it is uncommon for engines to experience premature failure caused by wear, whether they have been treated with Slick 50 or not."

 

I used Slick 50 and Lucas oil additive in my brand new Chevy 350 4-bolt main 300 hp factory crate engine. It was worn completely out in 60k miles and would not even hold oil pressure with 50w oil in it!!!!

I'll never use slick 50 or the lucas additives again...

What makes you think the Slick 50 or the Lucas additives had anything to do with the engine being wore out in 60K?

 

Well, I changed oil every 3,000 without fail. The engine was in a half-ton step side little short bed pickup that was a daily commuter. It was only driven by me, and always allowed proper warmup. It was never beat on or abused. Fuel filters, air filters, etc were all changed regularly.

After the fact, I found reports of many other people with similar results, including a nice concerned gentleman I ran into in PepBoys who saw me buying Lucas Oil Stabilizer.

I did some research on the web that led me to believe that.

I maintained my dodge 1/2 ton gasser the exact same as the chevy, except never used the slick 50 and Lucas, and the engine held great oil pressure and compression at 300,000+ miles.

I dont know that it was due to the slick 50 and Lucas, but that's the best I can figure...and several others' opinions as well.

What's your idea?

dont waste your money on slick 50 or any other bogus claims

The best oil available on this planet is Mobil One Turbo Diesel Truck.

Use regular oil analysis as well. Your engine will outlast you.

 

Slick 50 is a joke. Always was, always will be. Use the proper oil and go synthetic if you want extra, or add a bypass filter and do oil analysis.

 

Slick 50 means it is a slick way to get $50 out of your wallet. Snake oil if you ask me.

 

that's a good one! Hadn't heard that one before!

 

I use the lucas additive. Only one quart though. My oil anaylisis from Blackstone cam back a lot better with it. They recommended it, and of course I was leary. I tried it, and it seems to work great. Lucas recomend 4 quarts in my motor, but I only use one.

 

Read the stuff on bobistheoilguy.com about oil additives. Then don't put anything in your engine cept quality motor oils and you'll be fine.
Lucas and Slick50... I'm amazed that anyone still uses that crap.
Sucker born every minute, I guess.

 

Sucker born every minute! The oil anaylisis company (wont mention any names, but it is the one that everyone on here uses) told me to use it. They said that all of their test that they do on the 5.9 that use a bottle of Lucas come back excellent almost everytime. And no they don't sponser or get any kickbacks from Lucas. After I started useing it, test were coming back better and better.

 

If you're talking about Blackstone, I've been using them for quite a few years now. I thought they never recommended one oil over another??
and I didn't mean to call you specifically a "sucker"...

You'd have to show me in writing where Blackstone recommended Lucas.

 

Well yes it is Blackstone. Since we are naming them, I had an extensive conversation with a gentleman there and we talked about oil samples and oil specifically for the 5.9 cummins. I mentioned I used Amsoil, Royal Purple, Valvoline and Rotella. The last oil sample that I sent it, it was Royal Purple. He told me that the 5.9 Cummins does not really care for that paticular oil. He said that certain diesels respond diff. to diff. oils. He said that with the thousands of 5.9 test that they do, in his opinion the best oil for the 5.9cummins is Rotella 15w40. I told him that I usaully run Rotella Synthetic and he said don't waist your money. Use the 15w40. He said that if you were worried about cold starts or dry starts, use a bottle of Lucas oil. Lucas oil turns out to be excellent in the 5.9 cummins. I have no reason to disagree or not believe him. He is the one who test oils, not me. I have tried the Lucas and my oil samples came back excellent. Call Blackstone on Monday and just talk with one of the guys there about the 5.9/Rotella/Lucas combo. It seems to work for me. Test come back GREAT.

 

I've had great results with Delo, Valvoline, and Schaeffers. I would continue to use any of these. Lately it's been ValvolinePremiumBlueExtreme.
