Amsoil in new 6.4

[sd2009]

Can I use Amsoil in my new 6.4 or will I void the warranty? I would like to maybe put Amsoil for the engine and transmission. Thanks for your comments

I have been using amsoil in my 08 for 40000 miles except for one time my service manager gave me a free oil change to test Ford's new syn. I do oil samples every time. The Ford oil tested just about as good as the Amsoil. The Amsoil is quite a bit cheaper. Amsoil has improved their cj4 oil recently so I expect it will test a lot better. They are recommending 3 times the normal change. I still plan on changing my oil every 10000 miles. In answer to your question no it will not void the warranty as long as you change it at Ford's recomended intervals. All my oil samples have come back with good for continued use. I do not see any advantage of using Amsoil in the tranny. Ford fluid is syn.

I have a 6.4 in the dealership now all taken apart, blown high speed turbo and sludge found in the engine.
has denied repair simply cause they found sludge in engine.
Used oil analaysis was taken by me and sample sent in, came back as excessive coolant found in oil, I was using AMSOIL HDD 5W30 and it was in there for 19,000 miles.
the oil was found to be in good condition except for the contamination of coolant.
I am way ahead of the experts at and they will honor my warranty due to failure of engine oil cooler leak, inside of the radiator, they had already replaced the radiator before I took the oil sample, the service manager has not returned my calls yet today.
I guess he is trying to figure out how to read the UOA I sent him

where are you sending your oil for the exams, the dealership? I would like to have mine tested just to see how it looks.
Thanks

I just kept hunting around for a garage that new what I was talking about when it came to getting oil tested. Never thought about taking it to a dealer ( price). I eventually found a garage that works on rigs and Diesel pick ups.

Free test kit from Blackstone Labs:
Free Test Kit
$22.50 when you send in your oil sample.

I was a huge Amsoil fan when I was running my 2002 7.3, and ran their 5-30 diesel synthetic. I sent in samples at every oil change to Blackstone. At around 100k, I started getting some high iron readings. I changed my oil before 3k to see if it would clean up. It didn't, so I changed to Delo 400 15-40. My iron immediately cleaned up and I continued to use the Delo, with normal reports, until I sold the truck at 182k. When I mentioned this iron problem and Amsoil on this forum and also the "oil guy" forum, there were a number of other former Amsoil users that experienced a similar history at, or around 100k of Amsoil 5-30 usage. If anyone wants to see my Blackstone reports, I still have them. Just send me a pm and I will be happy to email them to you.

It will cause you serious problems with the warranty if you have a failure. The problem is that AMSoil does not API certify their diesel oils, so Ford has no way of knowing the it MEETS or EXCEEDS their spec for oil. It will be totally up to you to prove that, and it could be a long expensive haul. The other prat of your question involves the Torqueshift transmission which REQUIRES Mercon SP for it's fluid. No one but Ford markets a SP fluid, so if you use an AMSoil product there, you have no leg at all - it does not meet spec.

Why use a synthetic at all? Do you live in a cold climate area where cold starts are a problem? Do you plan on doing extended oil changes with bypass filtration? I've never found the cost of synthetics just not worth it. The ROI just isn't there for me. DELO LE is about half the cost of any syynthetic, and will go the 10k recommended OCI just fine. I have a 6.0, and it's harder on oil than the 6.4, being known for shearing oil. The DELO will go 7.5k just fine in my engine.

I've taken an OI at every change to track fuel dilution in my 6.0. With some of what I'm reading here, that may be a wise thing for 6.4 owners as well.

19k miles since the last oil chnage? Now you are asking Ford to cover the bill after running a oil with no API cert???? Sounds like a no brainer!!! Let me guess we'll start blaming Ford and jumping up and down when they refuse the repair???

That Iron # wouldn't be something I'd be crowing about. Lead isn't so hot either.
My average iron # is 24, and lead is 4. This is with 5000 mi changes over 100k+ miles on my 7.3L.
On a per mile basis, my iron is less than 5 per 1000 miles, while yours is 8.5/1000mi. My lead is less than 1/1000 miles and yours is over 2/1000 mi.

What that means to me is that engine is wearing out twice as fast as mine. Is saving a little money on oil changes worth replacing or rebuilding the engine? Not in my book.

Running AMSOIL will not void your warranty no matter what!

I hope Amsoil will if Ford won't. I'd get it in writing from Amsoil. I like to see if Amsoil ever sucked it up and paid for an engine warranty when their oil was used. Any examples??

Do you have an example of an engine failure with Amsoil? I have never heard of an engine failure with Amsoil. At least an oil related failure.

No matter how tempting I have decided to have all oil changes done at my dealer. I am still blown away at waiting so long between changes. At 15K I have changed the oil 3 times. Dont get me wrong I love the syn oils such as Mobil 1 and Rotella but the Motocraft is a blend and I have it documented they changed it. I have dirtbikes and this old and tiring arguement on which oil is best goes round and around. Lets face it, the oil is just about the only thing we can change on these machines so we all hope for some kind of miracle. Bottom line is run whats required i.e. CJ-4 API and have fun.
