If I remember right Bob or his family have been burned by MLM companies in the past. So Amsoil gets lumped in with every bad MLM company that ever existed (I guess The History Channel didn't realize they were a crap scam company when they profiled Amsoil in the show History of Lubes and Greases).

If you do a goggle search on Amsoil and API certification you will find a lengthy discussion on why they don't pay the money to get the API Licence on some products. It's up to each and every person whether they want to accept the reasoning or not.

I use Amsoil in 2 cars, 2 quads, my sand rail, and my motorcross bike, all with super results. I've used the 15-40 in my old Cummins Dodge for a few years and had terrific oil analysis results on 7,500 mile change intervals. I don't currently run it in my PSD for 2 reasons: The truck only has 8k on it (breaking in), and I don't put enough miles on it during a 6 month block to warrant spending the extra money on synthetic.

p.s. I believe Amsoil is the only company out right now that makes a fully synthetic oil filter cartridge for the 6.0

 

Yes you are right.. they manufacture there own oil cartrige for the 6.0L and its the extended drain (EA) filter. Supposed to be good for 25000 miles w/oil analysis if running an EGR.

Maybe we can keep this thread on topic and accually try help someone who asks a ligit questions?? Sure would be nice!!

 

It would be very nice.

 

As I stated earlier, Amsoil is concerned about the API Certification issue,
Check out this question, and answer right from their website:

Q: AMSOIL will be using a different formula for its XL-7500 Motor Oils. Why did AMSOIL change the formula?

A: Our XL-7500 oils are the oils of choice in the retail oil change market, and primarily because of warranty concerns the customers in this market require API-certified oils. In order to obtain API SL/ILSAC GF-3 certification and still remain cost-competitive with the other oils sold at retail oil change outlets, we had to change to Group III basestocks. To obtain API certification with our top tier basestocks would have priced our Dealers out of the market.

 

top 3 most boring threads

1 Amsoil????
2 what exhaust?
3 what tuner?

 

Glad this thread has stayed open for more than 1/2 day...This is interesting as I am considering what synth oil to switch to when my Ex hits 15K miles, and am not an Amsoil dealer, no affiliation, but have found a couple well-known distributors that have a following due to great results, etc. I know the product costs more, but don't mind an (established) individual making some money off me vs. WalMart, AutoZone, Shell, etc. IF 1) the product is a great one and 2) if I'm comfortable going w/ extended changes to help offset the cost.

I think the original post asks about 5w Amsoil, but the 15w40 "PCO" is the one that is CI-4+ rated and makes sense in my climate (TN), and will not jeapardize my standing w/ Ford, so this is the one I'd go with. Is this the oil that you are/were running in the Cummins, or a previous version of 15w40? I'd be nervous about the 7500 intervals, I guess you could have an analysis done at 5k and 7500 miles to see if ther's a difference for piece of mind. With the fumoto, would be easy to sample twice from the same oil, right? Has anyone done this?

 

Not to steer this boring thread in another direction, but here goes. Is there a major difference in performance between synthetic and the non-synthetic oils in these diesels? I'm waiting for my new 6.0 to get in on order (my first diesel) and have been wondering about this.

 

However...everyone has a questions and they need to be answered....that is WHAT a FORUM is about...

 

97nukeford, It might be better to start another thread for that question or go our specific oil thread:

https://www.ford-trucks.com/forums/f...splay.php?f=70

Trying to keep this thread on solid footing so to speak...Thanks

 

Okay, sorry! Just wandered off on a tangent there!

 

Not a problem...thanks again.

 

Bob,

The "XL" line they have is not the top-notch product from them. It was formulated specifically for marketing to oil change places as an alternative to offer customers other than the standard 3,000 mile oil change myth. By their own oil change interval recommendation the XL line is only recommended for half the duration of the full-blown best syn oil they make i.e. 6mo vs. a year on a change out (non-diesel oils). Yes, the XL has the API licencing taken care of, but it's only half as good as the premier product they carry (in my mind), even though the top-notch ones may not have the API licence.

Getting people off the 3k change interval is hard enough, then in order to avoid further roadblocks to the successful marketing of this specific niche product they decided to get the API Cert. They address the uphill battle with 3k myth and the uphill battle with any shops that may be leary of product not having the API licence.

You have a valid point of view on the API licencing, no doubt about it. They way I see it there's 2 camps: Those that will not run product without it being licenced, and those that look at the oil data and see that it's superior to what they were using, and then decide the API licence is less important to them than the improved performance.

To each his own.

 

Neither am I, and you don't have to buy it from a dealer if you don't want to (otherwise I'd probably not ever bothered trying it).

This is just me but the way I look at it is if I really want the best and have decided on a particular manufacturer I'm going with their premier product in the weight range I want. The PCO is a very "dumbed-down" version of their AME (IMO) i.e. it's semi-syn vs. full-syn and I don't think it uses the same quality base stocks and additives. It's probably very good compared against other conven oils but if I'm going through the trouble to get it (time/expense) give me the best one. I have yet to seen anyone that melted down an engine say that Ford sent the used oil off for testing to see if it was an API product. I don't know if I've ever personally seen a post that someone melted down an PSD engine for a oil performance issue.


I was using AME in my Cummins. I religiously oil sampled every oil change and crept up on the mileage interval based on how my analysis were coming back. Even at 7,500 mile change out on my old Dodge the oil was coming back from an INDEPENDENT lab (not Amsoil) "good for continued use".....I just chose to cut it off at 7,500mi. Now, CTD to PSD is apples-to-oranges. IMO even the same year/make truck can be different from on engine to the other. There's many advantages to oil sampling, if you want to do it go ahead and start out at a given range and increase (or not) as you see fit and more importantly, what the science (lab) shows you can do.

 

Two great post. Thanks for have taken the time to do that. . Rblomquist gets two gold stars and one ataboy.

 

Ya know, if the topic is boring, go some where else and don't read em. Its that simple. It may be boring to you, but others clearly what some info.

I use it currently in my 06 PSD with 7800 miles. When it comes time to sample, I will post results. I fully expect to run it for at a minimum of 10K. I ran it in my 5.4 and went 31K with bypass filtration. So we shall see.

P.S. I could easily wipe the floor with Bob and his baseless arguments, but I got things to do. Perhaps some day I will make the time.
