This is the response from ExxonMobil:

Thank you for your inquiry,

To meet the demanding requirements of today's
specifications (and our customers' expectations) Mobil 1 uses
high-performance synthetic fluids, including polyalphaolefins
(PAO, groupIV),
along
with a proprietary system of additives. In fact, each Mobil 1
viscosity
grade uses a specific combination of synthetic fluids and selected
additives in order to tailor the viscosity grade to its unique
requirement.

Mobil1 motor oils are 100% synthetic and offer the best overall
protection and performance in the real world. Consumers need to focus on
end performance not how we or any other petroleum manufcaturer gets there.

This is a typical nonresponsive answer that OTHER companies get lambashed for. The bottom line is that since they lost in court to Castrol, they have decided they too must join the deception party in order to maximize profits. Sell a Group III as a pure syn. Just because the courts say so doesn't make it real.<!-- KEN: 1-13-2007: show 300x250 ad-block to non-Club FTE users in the 1st post of every page --><!-- / Ken, end of hack --><!-- / message --><!-- no sigs except when logged in --><!-- sig -->

Scafes posted this in the 6.0 forum you must have missed it.

 

Wow, and we were just starting to make some progress again.

Pete, no, it is a problem specific only to the 6.0

Matt, I understand that it is only a 6.0 problem, and looks very good in the application he is using it in.

Like I said, by no means am I discrediting his info. It just confirms that I am doing the best I can by changing my oil ak 5k and skipping the testing.

Pete to answer your question a little better. THe 6.0 injectors are alot higher pressure than the 7.3, and to attain this pressure repeatably they need to have pretty tight tolerances. Any water or trash on the fuel side will scrap them pretty quickly. The oil side is just as tight, I think some of this was caused by the 7500 mile interval, but again no one is commenting openly or putting it on letterhead. The issues became non issues really quickly when the vast majority switched to the 5k mark.

 

You took the words right out of my mouth, Ryan!

Matt and Ryan both... thanks for the info.

 

Since this is my first post I know I'm going to get slammed on it, but here it goes anyway.

I owned a 2003 F-250 6.0 for 2 and 1/2 years. The only problem I had was a check engine light which was fixed by changing a wiring harness. At around 7000 miles I switched to the Amsoil AME 15w-40 and their filter. I went 17,000 miles on that oil and filter without a problem. 14 mpg the entire time, started fine, ran fine. I did an oil and filter change again with the same product. I went 18,000 miles the 2nd time around. 14 mpg, started fine, ran fine. Where I live, it is in the 20's in the winter and the 90-105 range in the summer. I sold the truck 3 months ago and the last time I talked to Chris, about a week ago, there were no problems. I never did a UOA so I know this statement doesn't carry much weight among the frequent posters, but it is what I did and what I experienced. Take it for what you will.

Remember, you dont need to be a posting guru to pass along useful information. It seems everytime I see someone post on here for the first few times they get beat into submission by someone.

 

Ryan, it sounds like the fuel delivery systems are same for the 6.0 and 7.3, except the parts are different. Do you know what the peak operating pressures are for the high pressure oil and the fuel pressure on the 6.0?

 

Actually, pretty amazing first post, if I was grading you, I would give you an A+. While you ran it and never had issues, you are one person. The same can be said for me running a tuner on my 03. I never lost one ounce of coolant and had 60K, yet many here on this very board running the same tuner had puking issues. So take it for what its worth.

 

Welcome to FTE and thanks for posting. Gotta start somewhere.

 

First of all let me say WELCOME to FTE and second we were all 1st time posters at one time . This site is about helping others and getting help on a problem you may have . I wish more people posted that way and would remember this when they reply to a post.

Good Luck and Glad to have you post here on FTE.

 

I do not know exact figures, (Tim, Matt, or anyone else greater versed in the specs of the 6.0 help here?) However I do know its more fuel pressure, Hpop pressure, and injection delivery pressure. They also have 2 fuel filters on the 6.0 instead of the 1 on the 7.3, which tells me they are very concerned about contaminants pasing through them.

 

Bob I aint ever been to the Amsoil website or heard anything they have to say, sorry. I just buy it, throw it in and run it w/ no problems. Race on it, or drive on it every day, I've never seen it fail, have you?

 

Welcome to the two new faces in the Oil and Lubrication forum...

Cool6.9DieselGuy and crimefighter

Thanks for joining us!

 

Hello Crimefighter! Good post. Kinda new too but sure have learned alot from all the readings. I too use Amsoil ATF but regular Rotella every 3-5000 miles, used to own a lube center so believe in regular changes and clean oil. Still do it myself so know it is done right. Hope you become a supporter. Welcome to FTE. Pay for three years and get a nice T-shirt!! Dave Tyler

 

Thanks for introducing yourself, Dave. Welcome!

 

Probably not.

 

Well I decided to write this post not in the light of educating Bob, but to educate the readers of these posts through my discussions w/ Bob regarding Amsoil. Dont get the wrong impression Bob I dont think you're a bad guy, you have your opinions, I have mine. But I do feel if you took the time you've spent bashing Amsoil and used it in a more positive way you may have even been able to develop your own line of lubricants that could outperform Amsoil.... I'm picturing something along the lines of that motor oil commercial in the early 90's where a guy was holding 2 frying pans both w/ motor oil and one burned before the other at the same temp. That would be fun right Bob? After this post I am done w/ the subject.

First off, I've never been to the Amsoil website, well maybe once like 10 years ago, but I do know a lot about lubricants in general and what makes Amsoil a great one. I've used their atf and gear lubes first hand, snowmobiles, outboards, cars, trucks, racing and/or daily driving. I keep the lubes clean, dont burn them up(they're incredibly hard to burn up), and I've never seen them fail.
The cSt specs that Bob has been crying about w/ the amsoil and other oils being different are not very important factors when it comes to the slight differences between them. Basically the amsoil flows as good as one, but then flows better than the other. Is proper cSt important for a transmission to operate properly? Yes... the lubes have to meet a few different characteristics, but see that's why you dont put things like 'gear oil' in an auto tranny that calls for 'ATF'(and it's 101 names), for the most part your protection would be great if you only had one gear, but other than that the chances are it would not shift and operate properly because the fluid would not be able to move fast enough to actuate the different moving and interchanging components inside. For the most part, the Amsoil apparently flows better than the other oils, it matches some cSt specs of other oils and is slightly higher or lower than those of ATF's with different names and 'certification' criteria. This does not however mean you shouldn't use it... it's a universal ATF, it's designed so that you dont need 100 fluids with slightly different characteristics to chose from. With cSt for example again, I personaly wouldn't go and use a fluid that had a lower cSt in something that called for a fluid of a higher cSt unless it was just a great lube overall. I would however use a fluid of slightly higher cSt in a tranny that called for a fluid of slightly lower cSt as long as it had equal or better overall characteristics.
So why doesn't Amsoil have stamps and certifications all over it? Well first off I guess because the people that use it know better, they dont care if it's 'certified' they just want the highest quality lube they can get and having the bottle that says Amsoil is enough proof of that to them. It's also probably an expensive process to certify through API or whatever. More important, like you can't expect it to be certified as dextron III or mercon X, it's not! There's nothing to be scared about, it's just not made by these gigantic corporations that control the industry and mass produce everything and have partnerships w/ the car manufacturers. However it is a much higher grade of synthetic lubricant. If it was the other way around you couldn't say mercon V(or whatever they make you buy now) matches Amsoil's specs. I guess what's most important is, the differences between all the ATF's out there and what these vehicles are calling for aren't very critical, the main reason they call for the newest mass produced ATF's is so that you dont go and do something stupid like put a bottle of original dextron in one of the more sophisticated transmissions that come off the line today. And Amsoil can't certify that it's 2 different fluids(it's only 1 fluid), especially when they start seperating fluid certification names by .5 cSt.
Here's a motor oil analogy to try to explain easier why you shouldn't be scared about using it... My Subaru WRX calls for 5w-20 or something really light like that... Now who the hell is gonna run that in a motor? well I guess the idiot that doesn't know any better... take your car to a GOOD local mechanic or even a regular oil change shop and chances are they dont have any 5w20 in a tank waiting for the next customer that needs 5w20(dont quote me on this completely though I dont tour around having shops change my oil, I wouldn't let someone I dont know touch anything on any vehicle I own). It calls for 5w20 but can you run 10w30? absolutely, it's a little heavier and would give someone of my driving style at least some better protection on the motor and I think any good mechanic would aggree. Can you run 75w90 it's oil too? now that's a huge difference of oil characteristics compared to the other oils and chances are even if it's the slickest 75w90 in the world it's not gonna flow through the oil pump good enough.
Bob what do you do when you need fluids for your model T? do you try to scrounge up oil that met the specs for the car back in 1920? Fluids have come a long way since then, sometimes you are even forced to use better fluids than what was originally called for but I'm sure you've found that out by now but just not w/ the amsoil. I have 2 stroke outboard motors from the 1940's that call for mineral oil to be mixed w/ the gasoline at like 12:1, MINERAL OIL!! 12:1!! It says it right on the manufacturers label crystal clear. Does that mean that's all I can use? I mean yea I'm sure it would work but oil is so much more advanced in this day and age, modern 2 stroke oil at 50:1 works better than the 12:1 mineral oil they were using back in the day. I guess that's similar to saying that the amsoil is a little more advanced as to compared to what these other companies are mass producing cheaper for you. Just for common knowledge did anyone ever tear apart a motor that was run in the 70's? There's a little bit or a lot sometimes of some black gunk inside... well how come if you tear apart a motor today there is no more black gunk you used to love? rebuild that same 70's motor today and tear it apart again in a few years and you'll find out it has to do w/ the quality of the oil being produced today which is much better than back then in the 70's to early 80's. If you were to use oils that were called for at the required specs set by the manufacturer from back then because that's what the manufacturer said to use, now that would just be silly, yes Bob I said silly. And how bout how the oil of today you can drive on for 5-10K when back in the day you could only drive on it for 3K? Anyone notice that these quick lube places still want you back in 3K but the car manufacturers are even giving you till 6K sometimes 10K in your manuals??? Amsoil motor oil I guess you can drive 15K. What does that say?
Many people might not agree w/ me, but from what I've seen these car companies that set the standards for your vehicles really dont care much about your vehicles, they care about selling it to you, they care about fixing it after your warranty is up, they care about selling you parts for it, why would they want you to use a better fluid in it then what they said should go in it? With motor oil they dont have much of a choice because of what's available. They more or less partner w/ the oil companies though once they list the oil company's 'specific' 'certified' oil that's supposed to go into it like with ATF. We're lucky they dont do this w/ motor oil. For all you know the fluid that's called for to use makes your parts wear evenly enough to be finished right at the end of your warranty.
So anyways, the slight differences between the oils are nothing you should worry about, be scared about, or cry about and say it's not good. Amsoils are made to stay really cool and protect metal parts exceptionally well. The ATF is made to help operate an auto tranny really well that's why they make it. I beat the crap out of a majority of what I drive and the amsoil holds up everytime. Somtimes fluids meet standards, and other times they outperform them. I'll leave you with one last analogy but I cant say it's the greatest but some might find it favorable.... the finest cuban cigars dont have certification labels wrapped around them, the finest bottles of tequilla dont have FDA labels on them.

Oh yea.... OEM is for suckers.
