OK, .....I have a 2003 6.0, getting ready to do my 2nd oil change.
Thought this might be a good time to go synthetic. I came across the amsoil web site and was sold on their oil.
However, I did come across some negative feedback from some of you more experienced diesel owners....HELP!
I have the oil but not in a hurry to use it, although they HIGHLY recomend it for diesel engines.
Of course Amsoil will recommend their oil! Its not certified by API, CI4 or otherwise. Ford recomends NOT to use oil not CI4 or a least CH4 certified. Your choice.
AMSOIL is the best on the planet, for the gassers.. well proven in the racing industry... I have no Idea how it runs in a diesel.. Id say good to go.

If you go back to the website you will see that Amsoil was the first synthetic to be API certified. According to my brochure its it CF-4, CG-4 CH-4 . I've used it for 11 years now in everything from tractors to lawnmowers and have never had a moments trouble. I would recommend it over anything else. Also what other oil maker gives you extended drain intervals if you use their filter. Thats one thing that sold me.
Not sure about the diesel grades, but SCAMsoil sure tries to trick gassers into believing their stuff is API certified when it's not. They even use a starburst-like symbol to confuse people. Not the kind of company I'd trust to do business with.
IS Amsoil API certified or not??? I have 4 gallons of amsoil and a partial of Rotella T in my garage. The both have the same API service ratings on the containers.
I'm a neutral person on what brands are better or worse, but there seems to be a lot of slamming of Amsoil for not being certified. Is there some small print somewhere that I'm missing?
I did purchase 4 gallons of Amsoil but probably won't use it. It sounds like the majority prefer Rotella T or Mobile.
All opions are greatly appreciated. I would much rather learn from any mistakes or incidences from the more experienced diesel owners than to find out the hard way!
I thank you ALL for your input on this subject.

SCAMsoil claims to meet various API service ratings. However, many of their products have not actually been tested and certified by the API to meet the claimed service ratings. Look for the API "donut" symbol on any diesel products you decide to use. http://api-ec.api.org/photo_library/...5W40_donut.jpg
WIth a coupon I can get the stealer to change the oil at $39.95 plus tax for the cheapest oil he can find. If I use a synthetic and go 6k miles in between changes that covers my cost, with the added benefit of the heat protection. Some of the synthetcs go for extended drain intervals which would save me even more money...
I just checked Amsoil's web site and their 15W-40 Diesel is API rated....

Better read closely. They (Scamsoil) claim it meets the API service requirements, but I don't see the API "donut" anywhere. The "donut" means that the API has CERTIFIED the oil. Of course, I don't have a bottle to look at, just the photo on their website... and nothing in that photo shows the oil has been certified by the API.
That's the crux of the issue: Company claims versus actual certification.
Just to let you guys know....You sparked my interest in the lack of a API certification....I have run amsoil for about 5K miles. I went out to the garage to get a bottle....and as it sits in front of me, smack dab in the upper corner of the bottle...is that seal that says " AMERICAN PETROLEUM ISTITUTE CERTIFIED" just to end any confusion.
I would stay away from any product that uses a brain washing, multi-level, get rich quick, marketing scam like Amsoil!!!!!! And in
this country, it is ok to put anything they wish on their own website!!!!
Besides the risk, just look tat the price you have to pay for the stuff, but that's because of the number of pockets your putting money into when you buy the stuff!!!
