Official UOA thread with oil poll

[UnleashedBeast]

Thats' a lot of dirt. I would inspect the air filter, unless its a k&n thats how they operate.

It's not due to the air filter in these cars. The first factory fill drain will yield ~250-300 ppm of silicon, the second drain ~100-150, until finally leveling off to 20-30 ppm on every change.

The more you change your oil, the lower the silicon ppm becomes in the 5.4L GT500 modular. The oil is leaching silicon out of the engine from the assembly process, sealants used, and certain types of casting parts.

Here is a sample of the factory fill of Motorcraft 5W-50 in a 2012 GT500. This sample was used for 681 miles.

Wear metals do not concern me on a break in fill, and will be ignored. Neither does silicon or oxidation. What does concern me is...

Viscosity: This sample has already sheared to a 40 grade lubricant (14.2 cSt @ 100*F) after only 680 miles of use. MC virgin viscosity is 19.9 cSt @ 100*F

TBN: Detergent additives are already down to less than 50%

Ordered my test kit, case of 10W40, and EAO11 filter. Will have 1000-1100 miles when changed since new. Ordered an EAO98 for my next oil change on my '11 6.7L F250 too. Always used WIX filters so giving the Amsoil filters a try.

The WIX filter is good, but the Nano fiber media in the EaO is above and beyond. That filter, with Amsoil diesel lubricant, will allow you to double and triple the factory recommended oil change interval in your Ford truck.

Using Lubrication Engineers Monolec Ultra 8800 15W40. Been using LE products for the last 20 years and I perform oil analysis. Never had an issue yet with any of my vehicles or equipment that is/was oil related.

Do you have any samples taken from a GT500 engine?

Getting ready to pull first sample with LE. I have samples using
Motorcrap and Castrol

I really want to see your samples. You have a low post count, how can I contact you through email?

I posted this on Team Shelby, but Unleashed is sleeping over there. So as promised, Mobil 1 15W-50 UOA.

Oil details:The oil was in for exactly 1 year, has 3,400 miles on it, and during this period my stock clutch went out. Other than that, it did sit in my cup holder for a couple months until I shipped it out, but should be a decent representation of the 15W-50. On the last fill I put Redline in, so we'll see.

Sorry about that, it's been kinda quiet over there, so I don't log in as much.

Thanks for the report. I will get this added to the list with the other two tonight.

TBN and wear numbers look decent, lead is a tad high. Viscosity sheared down to a heavy 40 grade lubricant over the 3,400 mile interval. This isn't a big surprise considering the formulation. I knew it would shear, but not as much as Motorcraft. A 15W-50 will be more shear stable than a 5W-50 due to a much lower concentration of viscosity improver polymers.

Your use of 5W-50 Red Line will be more shear stable than Mobil 1 15W-50. True synthetics do not require the use of VI polymers at all in most formulations. However, as previously proven...the use of 50 grade lubricants are too viscous in the 5.4L supercharged modular.

i just sent mine off on the Vavloline Roush 5w-50 with about 3400 on it too. i send it to you beast when i get it. i just used the last of what i had, so next time ill will be trying Rotella full Syn 5w40

Thanks for that! This is one sample I have really been waiting to see.

Then one day we will have a Rotella Sample to add. Most awesome! Thanks for your contribution. :beer:

First post has been updated with the last three UOAs sent to me.

Thanks for the contribution.

no problem it helps everyone out

Unleashed, the virgin visocsity of the M1 15W-50 is 18, so it is more than likely a true synthetic...in this weight anyway. The shearing after 3400 miles is 12.2%.

Typical Properties
Mobil 1 15W-50
SAE Grade 15W-50
Viscosity @ 100ºC, cSt (ASTM D445) 18
Viscosity, @ 40ºC, cSt (ASTM D445) 125
Viscosity Index 160
Sulfated Ash, wt% (ASTM D874) 1.21
HTHS Viscosity, mPa•s @ 150ºC (ASTM D4683) 4.5

I noticed that as well, but Blackstone had a different story to tell at first with an inaccurate VOA. I didn't use Mobil's spec, I used the VOA tested spec of 19.88. Now that I have the accurate VOA of 18.88 cSt, I will update the chart.

Which number would we consider more accurate, the formulators spec....or a tested spec? *This is a question, not a statement* I can use either.

as far as the base stock used, I've gotten reports that Mobil 1 now uses their VISOM highly refined petroleum in all of their main line formulations now. Even those previously told to me that didn't contain them. They blend VISOM group III+ with PAO group IV at undisclosed percentages.

The inaccurate VOA

The accurate "corrected" VOA - Viscosity is actually 1 cSt thinner than initially reported.

I will make the change asap on the chart.

Chart updated to reflect accurate virgin viscosity of Mobil 1 5W-50

 

[2008GT500]

Interesting... I know for a while M1 had 15W-50 Extended Performance, but I can't find a spec sheet on it. I'm wondering if the Extended Performance version had a higher VOA? I know you've done a lot more research than me on the subject, so maybe you can find the difference between the 2.

I will check into that for you.

A new UOA sample from a 2012 GT500 was sent to me today. It's the factory fill with only 1,000 miles of use. This is about the right time to dump the factory fill, as you can see wear metals are on the rise from the initial break in period.

The report looks very normal, but one spec overall shocked me. This is the first time I have seen oxidation this low on a sample of Motorcraft, or any lubricant tested from a GT500 for that matter....yet it's still flagged. Come on OAI...how do we satisfy thee? :smmon: I ignore this spec on all samples from OAI as it's become a wonder how they ever come up with it considering a virgin sample of the oil being tested is required to calibrate the machine for testing (so I'm told).

Again, viscosity has sheared to a 40 grade lubricant, no surprise here....that was expected. This time at only 1,000 miles of use. Why I know a 50 grade lubricant is over kill for this engine.
