Comments:

Silicon remains unchanged in this most recent sample from the engine in your Scion. Since wear is okay,silicon is probably from a harmless source such as a silicone sealer or spray. You may want to inspect the plumbing of your engine's air filtration system for leaks just to be safe. Maybe if you can get that silicon number down, wear will drop too. The viscosity fine for a 0W/30, and no fuel, moisture, or anti-freeze was found. The TBN was 2.1, showing plenty of active additive remaining in the oil. Try up to 12,000 miles next time.

I am still waiting on my 50K sample report, will post when received.

Not a bad run on this oil

I'd say the silicon is from using the K&N filter, putting a normal OEM or any paper filter in, and my bet would be a drop in silicon, and like blackstone commented, wear would probably drop also. And there are many posts about it here, but those filters really dont give much, if any, power increase; and basically no MPG increase.

Other than that I see next to nothing wrong here
great car and great engine!

 

[tomcat27]

ditto: great numbers, great oil! and lose the KN air filter. (IMHO)

 

[06tC]

Swapping the AF out at 65k when rotating the tires or at 70k when I change the oil again.

 

[ltslimjim]

I'll be posting a UOA of this oil in my high mileage civic, also running a K&N, but if I get high silicon I may switch to OEM. I did have the VCG replaced recently and not sure if the Honda bond may cause the number to be high?

 

[FZ1]

Run the oem AF.

Ditto. Nice report.

After only 10,000 miles on the oil, isn't the TBN a bit low? This is supposed to be a 15,000 and 25,000 mile oil depending on the service type.

That depends. If the oil was in service for a year, then no, the TBN is fine. If the oil was in use for 6 months, then yes, the TBN is on the low side.

up to!!!the miles

Actually is it 1 year 35,000 miles normal use, which ever comes first.

Or:

1 year 17,500 miles severe service, which ever comes first. HTH

OT- I wonder if these numbers are going to change in DI engine applications, or sludge prone engines? I wonder if all the oil companies are re-thinking OC intervals in DI engines?

No. You are wrong. You are thinking of the 0w30. Amsoils own website currently gives this for the 0w20:

SERVICE LIFE
AMSOIL Synthetic 0W-20 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline-fueled vehicles as follows:

• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first.

• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.


Either way, the question remains: For an oil that touts those two types of intervals (both longer than what the OP traveled) isn't the TBN a bit low?

This analysis is for Amsoil SSO 0W-30. His point is that it's "up to".

Mainly what you aren't considering is:

a) This is Blackstone scale, always low and not that accurate.
b) We don't know how long the oil was in service.

A 2.1 TBN could go on to 17K, as it's not linear. And again we don't know time. I would like to see the TAN first.

Amsoil does account for sludge prone engines.

OP used SSO 0w30 Amsoil's very best oil.

The numbers I gave are correct for SSO. ASM has different specs, which are what you've posted.

How about DI engines? I think they are going to be every oil companies nightmare, [ please note "every oil company"] and OCI's will be re-written for them. JMO

 

[Pablo]

DI Engines are in the Severe Service category, but I too would appreciate some clarity and specificity.

 

[Jehartley]

My apologies dermarpaint. I misread the thread title, I thought we were talking about the 0w20 to begin with.

 

[Jehartley]

In addition, Pablo and Dermarpaint, my wifes Camaro is the GM DI V6. The car has never used any oil, but I have been following the OLM (which usually puts me at 9,500 to 10,000 miles OCI's)and now I am wondering what might be the safest OCI for this engine.

Go back to old school 3,000 mile OCI's or maybe 5,000?

Let me put it this way, IMO [all the oil companies] most likely will be re-thinking OCI's for these engines. If it were my vehicle I would settle at maybe 3500 miles with a good synthetic like M1, PP, PU, Edge, Amsoil XL, etc, until there is more data. I would not want to be testing any oil or engine, at my expense. It appears there are issues with these engines. JMO

Go to the OLM, take a UOA from an accurate company and make an educated decision rather than an educated guess. If you take anything from this website, it is that you question blanket statements like demarpaint's 3500 mile recommendation and request scientific proof. Demarpaint may provide a useful suggestion but the engineers that built your engine also designed the OLM and demarpaint was not on the engineering team.

Your warranty covers you for your OLM interval (fact), a UOA will help you determine how long the oil is protecting the engine (fact). 3500 miles is a pseudo random number generated without evidence (fact).

 

[demarpaint]

Correct I wasn't on the engineering team. But read the problems popping up with DI engines and how hard they are on oil. We have a recent Schaffers UOA in this section that showed the oil was spent long before it should have been. There are similar UOA reports with other oils in DI engines. True this doesn't apply to the OP we drifted a bit OT.

https://bobistheoilguy.com/forums/threads/schaeffer-7000-5w30-2010-equinox-4-cyl-di.146585/

As you stated he could go with the OLM and then get a UOA, at least he'd have data, assuming the lab report is accurate. He wouldn't know about sludge building up though.

Blindly following the OLM IMO is a mistake, especially in DI engines. Being overly cautious or obtaining data for DI engine owners is prudent. Oil is cheap, engines aren't. Searching this board about the problems with DI engines is a real eye opener. I think the oil companies and car companies are going to be making some changes, in the form of recommending shorter intervals with these engines and reprogramming the OLM for DI applications. I'd rather be ahead of the crowd, than cursing the car maker and the oil company, saying I should have changed my oil sooner.


Engineers make mistakes too, plenty. My OCI was a suggestion, nothing more. I bet following my suggestion until the engineers and the oil companies get their DI engine ducks in a row will yield a cleaner better running DI engine than following the OLM. For the record, JMO.
