For you Scamsoil users:

Scamsoil has a reputation for deceit, like many MLM companies! Matter of fact, they try hard to make you believe that all of their oil products are API certified, in reality, there is only ONE (XL).

VW and Audi have engines that are prone to oil sludging (along with Saab,
Toyota, and Chrysler). VW and Audi have developed their own tests for oil sludging, and here are the approved oils....Notice that Scamsoil products are
missing, but Castol and Mobil-1 are there:

To make this even more intersting, Scamsoil issues this TSB, recommending to use their ONLY API certified oil product (XL) and to follow the vehicle manufacturer's OCI,
instead of the extended OCI BS that they try to justify the highly inflated prices of their products with. The reason for the inflated prices is due to the pyramid marketing
structure:

In a discussion with Blackstone Labs, who do UOA, they said that a UOA
test would not detect oil sludging.

 

Think with your DipStick Jimmy!!!!


I've filled up with Mobil 1 in both our vehicles last oil change. Not sure If i like the idea of changing every ~6k, I havent even put 2k on my truck in the last 9 months



Scottg

 

I go at least 10,000+ between oil changes. In fact, when I changed the oil last month, I don't even know how long it was but it was way more than 10,000 miles. I do this because I'm lazy, cheap, and it seems to have no detrimental effects at all. 3,000 miles FTL

 

Ohh God here we go again. "Scamsoil" haha. I use the XL oil and it's good stuff.

 

Mobil 1 as well, 5w-20 my whole life baby

 

I also use and know plenty of people that use Amsoil with no problems at all.

 

Yeah, like using Amsoil is worse than using conventional oils. Pretty sure you just can't go wrong with anything synthetic.

 

Only if it isn't API certified, a requirement by ALL US vehicle manufacturers for the warranty to stay valid. Most conventional oils ARE API certified.

 

So you void your warranty...big deal. haven't had one in 5years.

 

Motorcraft syn. blend 5w30 for 5,000 miles

 

Motorcraft 5w30 synthetic blend. . . seems to work fine for me so far.

 

A buddy of mine changed recently in a 04 4 banger. He said it seemed to him it made the truck run smoother and improved his gas mileage a little. I was thinking about switching over and wanted to know what everyone else thought about synthetic. If it improved anything or if they didn't notice any change at all.

 

Royal purple for the last 30k miles.

 

How do they know what oil you use? Is there a test for that too? It will name the exact oil you use?

 

The API certification tests!!!! DUH!!!!!!!!

 

Ok and what happens if it passes? Just because it doesn't have a certain certification doesn't mean it wont pass. I doubt the dealership will test the oil.

BTW. 122,000 miles on my truck running aftermarket parts and Amsoil.

 

What ever is in the 55 gallon drum of 5-30 at work.

 

So when the oil comes out of the truck, does it say "Hey look at me, I'm not API certified so void my warranty!!"

 

Only XL will PASS!! If the other products would PASS, they would be API certified!

Matt, are you familiar with the testing oil has to go through to be API certified? The oil would be tested Matt, if there is an engine failure
under warranty.

Why do you think Scamsoil recommends their ONLY API certified oil (XL), and vehicle manufacturer's recommended OCI in sludge prone engines?

 

If I had a sludge prone engine then I would switch to the XL. I never saw Ford Ranger anywhere on that PDF.

Ether way my truck runs fine and I will continue to use Amsoil.

 

You missed the point. XL isn't even Scamsoil's "TOP" oil product, but it is their ONLY API certified oil product.

Let me try and help you......if there is a warranty claim, Scamsoil doesn't
want the oil to be blamed due to it not being API certified......This would seem
to imply they have seen engine warranty claims denied due to their NON API certified
oil products, AND EXTENDED OCI's!!!

 

Here you go buddy. Straight from the source "The true milestone came in 1972 when AMSOIL became the first synthetic motor oil in the world to meet American Petroleum Institute criteria"
This came right off of amsoil's website.

 

I think you answered your question in your thread here:

Excessive wear from aftermarket parts and Scamsoil!!!

 

Too bad it didn't continue..........

 

So what do you think is the best synthetic?
