Official UOA thread with oil poll

[NuclearPower]

Still amazed at how fast my Amsoil gets here. I ordered Friday afternoon and the UPS guy dropped it off today! I'll be sending in my first Amsoil 10W-40 sample with 5000 miles. If it looks good I will extended my interval to the factory recommended 7500. I'll send in the UOA to Beast when it comes in.

I eagerly await to see that sample. Thank you my night glow friend. lol

Here is the very first known UOA of Roush 5W-50 in the Shelby GT500. *That I recall anyway*

Wear metals look very nice, as they should. Your engine has over 20,000 miles in it, the break in process is long over. Lead is following the trends of other 50 grade lubricant samples taken from the GT500. I've seen lead ppm in Motorcraft 5W-50 low as 2, or as high as 22. Between all known MC 5W-50 samples, I've calculated the average of lead to be 8 ppm. That being said, you are in the average window. If you are still concerned about lead/bearing wear....all of my Amsoil UOA samples has never shown more than 2 ppm of lead, and I do not baby this car. I treat her like a prostitute.

This lubricant has a more robust detergent additive package than MC 5W-50 ever had. The TBN is still at 5.9 after 3,200 miles. MC would be only be 50% of that amount after this many miles. I did notice that you had one quart of make up oil. This does benefit the TBN reading, and would boost the amount of detergent additives in the tested sample.

I see a small level of Manganese in this sample. Have you been using any Torco fuel additives or race fuel? If so, that's to be expected.

Viscosity (17.0 cSt) started out much lower than expected from other 50 grade lubricants commonly tested for the GT500. It sheared to a 40 grade, as expected, but not nearly as bad as MC 5W-50. Sheared only 15%

Here is the VOA of the same oil for comparison you posted a long time back.

In conclusion, this is a better alternative for those who insist to use the Ford recommended 5W-50, however as most of us know...it's no longer available.

Thanks troy for the review I'm on my last oil fill of this brand an will send out too when I change again. This time I will not add a qt. If I need oil ill just change it out at whatever miles its at so I can get a clean sample. Then ill be try rotella 5w-40

I will say that I've never really been found of Rotella, even though it does return good UOAs on BITOG.

Rotella uses a mixed formulation of magnesium and calcium as a detergent additive. Some of the tribologists have suggested that magnesium has the tendency to build up deposits in a gasoline engine. I don't know the details, or how severe...but I understood their explanation of the process.

My predictions, Rotella will shear to a very light/heavy 30 grade within a 3,000-5,000 mile interval, just like Motorcraft 5W-50. The TBN "detergent additives" readings should look good, as this is a primary diesel lubricant. They commonly have very high TBN virgin content.

Let's wait to see how accurate I was. ;-)

Oil Change

Just changed the oil. Drained Amsoil 10W-40 and filled with Amsoil 10W-40. Have 5000 miles on oil and will be sending out on Monday. I'll send the results to Beast once I get them in. I am looking forward to this as I plan on extending to 7500 miles if the sample is good. The oil looked just as dirty as the MC, I presume this is normal for all oils to darken(?)...

I also checked the JLT oil catchers on both sides...I will post this in the Bob's oil catcher thread also. Very disappointed...:fm::cuss:

I don't think that they are working like they are advertised to...the driver's side was bone empty. Didn't even look like any oil had ever been inside - not unexpected based on everybodies observations.

The passenger side I was expecting to get a good bit based on others posts...I got enough to coat the inside of the can but that's about it! Not enough to drain into a medicine cup to measure. But I found oil at the inlet to the supercharger, just touched it with my finger and a drop of oil was on my finger tip!:fm::cuss:Isn't it supposed to prevent this!!!!! WTF..anybody out there help me understand?:shrug::??:

The oil will do 10,000 miles easy.

Being dark/black is normal. That doesn't determine the quality of the lubricant, and how much active additives are remaining. What it does show you is the lubricant is doing its job cleaning your engine.

I commented about the catch can in the other thread.

Hey UB,

How does time factor into the mix? Should I push it to 10K even though it might take 3 years?

Thanks!

Never!

Anytime you see me say, this oil will be good for XX,XXX miles or one year, whichever occur first.

The only time I ever recommend allowing an oil to go beyond one year in your engine is if you barely drive it. Even then, don't go beyond 18 months.

This UOA is unrelated to the GT500 community, but it is another testament to Amsoil's quality. This may be of some interest to the Ford/Chevy/Dodge diesel truck owners who post here.

This sample was taken from a 2008 Chevrolet 2500HD 6.6L Duramax turbo diesel. The truck has a lift kit, custom wheels, aftermarket exhaust system (DPF delete), and aftermarket tuning. It's been six months and 6,000 miles since this oil was poured into the sump, and the results are better than anything I have ever seen before. The amazing part is...there is no bypass filtration system on this truck.

The lubricant tested is Amsoil DME 15W-40 and an Amsoil EaO52 screw on oil filter.

Wear metals are extremely low. I've never seen them this low on a 6,000 mile interval without a bypass filtration system installed.

Viscosity is consistent @ 14.4 cSt and it's still a 40 grade lubricant. Virgin specs are 14.6 cSt, so this lubricant only sheared 1%, very nice! That little shearing could be the difference in testing environment, meaning it actually did not shear at all.

TBN is still healthy @ 6.79, virgin specs are 10.4. This lubricant will easily achieve a 15,000 mile oil change interval or one year, which is the schedule I told the owner to use.

There have been documents warning 2007+ diesel truck owners about fuel dilution problems. The owner had this sample taken to see if fuel dilution was a problem, but this report indicates everything is perfect. No fuel dilution problem here.

Any of you guys that have a diesel truck wanting to minimize oil changes, yet protect your truck better than ever, you really should try this lubricant.

My truck isn't a diesel but since switching to amsoil I have noticed considerably higher gas mileage. Waiting to see what my next UOA looks like in the Shelby since the switch, sadly it won't be until summer.

Good to hear about the increase in efficiency. I know what you mean about taking forever to get an oil sample. My car wasn't driven for 6 weeks straight just before Christmas.

Beauty and garage queens...you guys are so lame...:loser:

You guys would kill me for what I just did to my GT500. Keep in mind it is my DD and we only have 2 cars in the family. I had to park it at the airport garage for last week...but this time it has to sit in the airport garage for about 2 weeks! I do oil changes every 3-4 months! Somebody has to pay for Beast to be a pimp I guess...:beer:

Hopefully the wifey sent the sample out this morning so I can get it to you next week sometime!!:rockon:

Cause Pimpin' ain't easy!

Depending on the lab you sent it too, OAI is on the ball. It only took two days for the last sample I sent in last week. The results were already in my inbox.

 

[SVTORANGE]

Great information - thanks

Here is another Motorcraft 5W-50 sample that was submitted. Thanks for your contribution to the GT500 community Michael.

Wear metal levels in the new 2011+ aluminum block seems to be improved over the previous iron block. This engine is still new, so these numbers will further decline.

Viscosity is a very light 40 grade lubricant. This is expected and normal for MC 5W-50.

Overall, things are doing fine, but I'm still not a fan of MC 5W-50 as this engine does not require a 50 grade lubricant.

I'm assuming since fuel dilution has decreased from the last sample that perhaps some driving habits have changed. Maybe no more short trips in the car giving the oil more time to heat up and evaporate contaminants. It could also be that the first sample was taken from a cold oil fill?

TBN shows consistency with other MC samples showing this oil is 5,000-7,500 max duration of use.

Beast, I'm really confused. I read this whole thread as far as which oil to use. 10w30 or 10w40 and which filter to use. I'm about to change to the C&R rad and the 170* t-stat. I've been running redline 5w50 for a while and live here in Jersey. As far as the oil filter, i've been using Ford Motorcraft and and from this tread i should switch to the Amsoil EAO11 or the Wix?

With the 170* thermostat and C&R cooling setup, you are going to want a thinner viscosity lubricant.

Amsoil ATM 10W-30

Amsoil Ea011

*Unless you are long session road racing - which calls for Amsoil AMO 10W-40*

 

[Buddah]

i appreciate that good sir. also, can I run that all year or change it up during the summer?
