Maybe I'll go that route too. If your even remotely getting up on 15k that's well worth the money. I been changing 3k just out of habit with GC.

Amsoil claims 25,000mi intervals on their Signature Series for normal conditions and 15,000mi for severe applications (which includes turbocharged). For this first go, I sent in a 5K sample, and I'll send in samples every 2500mi until I get to 15K or i need to change it sooner. I could do a lot of oil changes for the cash I'm spending on analysis, but I'm hoping it will save me in the long run and/or help provide some insight to the community.

I've been off topic for a while now (sorry), so I'm going to stop replying to this thread before @ZSHO yells at me.

Dammit miwiau that was going to bug me......i just called amsoil and they dont show on the web page but the 0w-30 meets the ford specifications for the SHO

Sorry to drudge up an old post, but I wanted to clear up some potential mis-information. Up until my timing chain recently failed, I was running 0W30 Amsoil SS. After additional research, there seems to be a lot of speculation that the timing chain stretch is somehow cause by oil/oil contamination. Maybe it was my one-time experiment with extended OCI with the Amsoil SS 5W30 that cause irreversible damage, maybe it was the 0W30, maybe it couldn't have been prevented - I don't know - but this experience has caused me to re-evaluate my oil choices moving forward.

Long story short, earlier today I e-mailed Amsoil technical service: "Does Signature Series 0W-30 (AZO) also meet Ford WSS-M2C946-A specification?"

And just received a reply:

Mike,

No, the AZO does not meet that specification however, our Signature Series 5w30, product code ASL does.

Thank you for contacting AMSOIL Technical Services.

Have a great day, and please let me know if you have any further questions.

After my $3k repair, I'll be switching back to the 5W30 SS, which meets the Ford spec. For anyone still under warranty consider the AZO evidently does not meet specification, so oiling related failures may not be covered under warranty when non-spec oil is used.

Cheers!

Everyone has their plans and ideas. This is what my Dad taught me.

Change it sooner than later. Every 6 months and or 5000 miles Max.

Oil is cheap. $30 for a home done synthetic oil change with filter.

There are many high quality oil brands out there far cheaper than Amsoil/Redline etc that will yield the same protection following the change it sooner and often mentality. I understand some people/Fleets cannot follow this.

I use 5w/30 Castrol Magnatek which is testing very well lately online. Usually runs $25 for 5+1 at Wally world.

Oil List. Not too current but with some recent updates.

Exactly, I am actually going to switch to the Castrol Magnatec for my next oil change.

Mike, do you remember WHEN you purchased the 0W30 formulation.  I believe the pre-Nov 2017 formulation had some ... issues ... with regards to volatility etc.  But yeah, if you are going to work that powertrain, you need mfr recommended oil weight at MINIMUM.  0W oils are primarily for fuel economy, some wear, but really if you look at the specs, see what temps your vehicle is most likely to experience.   Look at the cold pour point.  If you have cushion, stick with 5W.  If you really are pushing it, then you would look at 0W, but a premium 0W, if you are, again, work that powertrain.

Indeed! Looking back at my Amsoil order history, this is what I found:

Case ordered Feb 2017 (~15k miles)

6 qts ordered Jan 2018 (~7500mi)

Case ordered Jun 2018 (~15k miles)

6 qts ordered Mar 2019 (just before timing chain replacement, still have)

So, I would have gone approx 15k miles on pre-Nov 17 0W30 SS, and just under 37.5k miles (tuned) in all on 0W30.

I'm planning to exchange the stuff I just bought. Now that I'm back to stock, I'll just stick with mfg recommended 5W30.

Additionally, I had been going 7500mi between changes, and I think I'll revise that to 5k. Funny thing is looking at the onboard oil monitor, it wouldn't have me changing until a 10k interval. That seems insane, especially on the OEM filter.

You gave me similar (and solid) advice in my oil analysis thread a couple years back as well. I tend to learn the hard way, but it's my own doing.
