Hi I just got my first F-150 friday, it's a 1998 Supercab with the 4.6L V8. This is also my first post here I just joined today, so hello all. My question is how do you guys feel about using slick 50 or dura lube in the oil? Anyone us it and will it really help extend the life of the engine?

 

I don't believe in it. I wouldn't use it in my engine I dont think it really helps. If I had to use one of these products I have heard more good things about poly-dyn tx7 than slick 50. I do recommend using synthetic oil, I think it holds up better than the natural product.

 

051F8991,

First off -- welcome to the board!!!

Secondly, regarding your question: I don't use them and have never had any problem with my engines (have owned multiple vehicles with over 130000 miles). Have also not heard anything but bad things about these additives on this board. Stick to regular oil changes and maintenance and you can't go wrong...

 

I've personally have never put any additives into my truck since I bought it new a few years ago. I did however use Slick 50 in my old T/A (that had a 4 barrel Carb.) Made a lot of difference in the morning as far as the amount of time it took to start. (especially in the winter.) Other than that, I'm not sure what else you could really tell.... Not sure if you would notice much difference on a fuel injected vehicle or not...

 

I started useing Dynosurge http://www.dynosurge.com/testimonies/richard.html
in my 01 Lightning after 1,000 miles when I also changed over to Royal Purple Synthetic oil.

Dynosurge is a 'metal-treatment' not an 'oil' additive. I now have 23,500 miles of daily driving, 1/4 mileing, and 5 dyno pulls. The eng. makes no internal noises(piston-slap, etc.), has no measureable oil useage, and makes lots of power.

No, I don't sell it but I like the results.

Welcome !! Change your oil and filter regularly with high quality products, and save your oil treatment money for a more useful investment.

 

I've never used oil additives and probably never will. I've never had any oil-related engine problems either.

 

Welcome 051F8991, Dupont produces the Teflon for Slick 50 and they themselves won't recommend the use of it in internal combustion engines. Also, either Duralube or Prolong (can't remember which) turns to something similar to household bleach once broken down. I've got a friend who is a technical consultant for an airplane racing team and he 's seen firsthand how this stuff can corrode bearing surfaces. I agree with the rest, skip the snake oil and put your money toward quality oil and filters.

In short, the FTC releases above indicate that all of these companies have used deceptive advertising in order to mislead consumers into believing that their products offer advanced engine protection and performance over motor oil alone.


Looks Like the Gov like them too.

First off, although there are a number of good oils on the market today, there are at least a few companies whose integrity should be looked upon as somewhat questionable. Specifically, when companies such as Valvoline and Quaker State (Quaker State is the manufacturer of Slick 50 Engine Treatment) utilize such deceptive advertising in regards to their oil additive products, how much weight can you put on advertisements for their oils?

 

I use dynosurge too. 98 5.4 186,000 miles. I think it helps 5/30 mobile one and filter every 10,000 miles. Stills runs strong.

 

I had an '84 VW GTi before buying my '01 XLT SCab.

The GTi always ran hot - it had an oil temp gauge in the console, it read Degrees Celsius, and the car always ran at 140 - 145C. Red line was 150C. In the summer in the desert, it would easily redline on a grade if I didn't back off on the speed. Turned out much of this was due to a non-VW radiator that VW of America was using. True VW radiator 2" wider as I found out later.

Anyway, I ran Mobil 1 15W-50 and then started using Slick 50 at about 40,000 miles. Much to my amazement, the average oil temp decreased 5 to 7C after adding the Slick 50. This wasn't my imagination, I had spent literally years watching that gauge to make sure I didn't redline it.

Consumer's Reports has always bad mouthed Slick 50 (and synthetic oil too for that matter.) I think Motor trend was saying 15 years ago that Slick 50 only showed measureable benefit when used with synthetic oil. They supposedly used a chem lab to help form an opinion.

But that's my experience with the product. Don't think I'd ever use it in the F-150 though - it doesn't run hot at all, no need for it.

 

Can you say Snake oil? Just change your oil on a regular basis and you will be
fine!

 

Another "snake oil" vote from me.

I read somewhere that in an independent test they did the slick 50 and prolong treatments to engines, drained the oil, and apparently all of the test engines seized in short order.

At worse the junk in the additives will break down into harmful chemicals or clog your oil filter involking bypass mode on the filter so no filtering effects what-so-ever.

Use Mobil1 synthetic oil and a Mobil1 or K&N oil filter for best insurance.

If those oil additives were so good then all the oil companies would already have them in their oils.

 

Thanks for all the advice, I think i will just stick with regular oil changes and forget the snake oil.
