Does anyone have any experience/factual knowledge about this Duralube stuff.

They make engine treatments/additives which they say greatly improves the life, performance, and a bunch of other stuff...

If it works, is this stuff only for older cars??

And, how does it compare to the other additatives like Prolong? or STP? or is it even worth it???
thanks

 

All this stuff is snake oil. Its a waste of money and potentially harmful to your engine. If you want max protection, run Mobil 1, Amsoil or Royal Purple.

 

Redline is also another good oil.

 

Duralube and all of the other Slick 50 rip off's were sued by the FTC and either folded up or paid out huge sums of money. ALL OF THEM! The chemicals used in most of these products will actually rust internal engine parts.

 

I used to use engine additives like Slick 50 and Prolong in my old '93 Civic. At the time, the engine probably had less than 60K miles under its belt. Even my mechanic used and recommended that stuff. However, after a while I got lazy about buying that stuff and stopped using it at around the 100K mark. When I traded the car in, the engine was still running fine and that was at 239K miles.

I heard that a lot of those products do build up harmful stuff in your engine even when they claim there should be no build-up under the extreme heat. My mechanic later told me that he had stopped using those things too for the same reasons.

Moral of the story...don't use engine additives. With regular preventive maintenance, your engine should last a long time.

 

Yea I stopped using engine additives after I heard about MotorUp getting sued and refunded money to everyone who purchased their product.

 

I used to think Slick 50 was a waste if money until I saw how it saved a 7.3 liter diesel engine. The oil was drained from the truck one afternoon. The next morning, the transmission fluid was drained and refilled. Nobody checked the oil because the person that drained it the day before said that the only thing left was the tranny service. I started the truck to take it around the other side of the shop so the boss could drive to town to buy repair parts for the shop. The boss drove about 2 miles down the road when he noticed that he did not have any oil pressure. He turned the engine off and had a mechanic bring him 12 quarts of oil. Poured the oil in and went on his parts run. That was in 1997. We still have that same truck with over 200k miles on it. The engine has not had any internal work done on it ever. The engine ran at least 6 minutes without any oil in it abd suffered no damage.

 

When I get to work tomorrow, I'll post the link to the FTC's site. Slick 50 lost big time and they were unable to backup any of their claims because they didn't test their product. The truck still had some oil in it which allowed it to go 2 miles. They are all Snake oils...... Don't you notice that NOT ONE of them is still running infomercials!

 

I know the truck had some oil in it but it was 3 gallons low. The refill after changing the oil filter and oil is 12 quarts. I know they stopped the imfomercials some time ago. If it is snake oil, it worked for that 7.3 diesel. I'm not saying to go out and buy some. Just saying that it helped that engine.

 

I haven't seen any of those engine additives informercials for a while now.

 

The only one that didn't have to pay was ZMAX. Nascar was behind ZMAX. They promised the FTC that they wouldn't advertise anymore and they got off without any fines. I think it was consumer reports that tried draining the oil and running the engine with these additives. Slick 50 was one and so was Duralube and Prolong I believe. Needless to say all engines seized in no time at all.

 

I got my money back from ZMax.

They may not make certain claims but they still sell it and make some other claims.

 

Actually, on that site, I didn't see one claim for the oil additive, it was only the fuel system treatment.

Come on. Even KMart brand oil is allowed to claim that. After all, it's petroleum based.

 

Will Kmart oil give you a 50k mile warranty? They just toned down their claims from previous years. They are still claiming some of the same things in different speak.

 

Please enlighten me on the warranty. It lists nothing on their website. Please post the terms of Slick 50's LIMITED warranty. They state you have to change your oil at regular intervals and use Slick 50 with every oil change. If you don't does it void your warranty. Here is Amsoils warranty and it's good for unlimited mileage.

It's not my warranty dude. I just pointed you to the website. I'm sure that you can get the details from Slick 50 if you want them.

 

I was unable to obtain any warranty information from their site. That's why I asked. I thought you may have had some literature and I was curious to see the fine print.

 

I did not see the details on the website either.

 

It's a really weak website for such a large company.

 

You know they have to be careful because of that FTC order.

 

I don't put that $hit in my car. I know about them how much residual contimnate the engine thus ruining it. Even clogs up the filter. I saw it on consumer report magazine. It was pretty bad.
