M1 5w-30, 5.520mi., Toyota Camry 2.4 (2AZ-FE)

[Bebop367]

I had some UOA's in approx. 2008 and they were very normal (lot less Iron etc. than this one)
This car was wrecked and in body shop approx. 8 weeks.
Blackstone Lab. and they flagged Iron and Alum.
Could no running for approx. 8 weeks cause the high Iron of 31?
Comments / suggestions welcome.

What is the universal average for iron and upon how many miles is it based? It should be noted on the UOA report.

 

[krismoriah72]

does this camry consume oil?

 

[SumpChump]

Wait... 5W-30!

Isnt this engine the SAME guts at the new 2.5L which demands 0W-20?? or have they made the passages smaller?

 

[OVERKILL]

If the car sat outside or was started and moved a few times, the condensation in the bores would indeed cause slightly elevated iron. I had this happen with my Town Car (though way worse) when I had the engine apart to do H/C/I on it and UOA'd the fill I dumped afterwards.

 

[Bebop367]

Univ. Averages Iron is 14 based on 5,900 miles

 

[Bebop367]

None

My Bad!
It's a 2005 Camry. Three Toy's around here and I got confused.

 

[Bebop367]

Thanks, I am hoping that sitting added some of the iron.

 

[Bebop367]

Correction - It's a 2005.......Not 2010

I think Overkill has it right, since you are in a damp climate.

I was wondering how one would do a UOA on a 2010 model in 2008. That clears it up

 

[simple_gifts]

Here he is similarly confused a few months ago.

Maybe his kids have tags on them?

 

[tig1]

The acceptable level for iron is up to 150PPM. Your good.

 

[Bebop367]

Thank You Tig1.....
I am going to sample the next two OCI to get a trend.

695 Magnesium?? I thought Mobil1 5w-30 doesn't have Magnesium.
Seems to be Mobil1 0w-30??
Cheers.

toyota62,

All SN/GF-5 Mobil 1 oils, to include HM (with the exception of 0W-40) use a calcium/magnesium combination of ~1050/650ppm, as a detergent/dispersant package.

Interestingly, Castrol Edge/Syntec does as well, but in the opposite amounts, ~650ppm Ca/1050ppm magnesium.

I'm sure one of our BITOG chemists will tell us how that switch affects the starting TBN and probable TBN retention. Both formulations are a result of a trend to produce lower SAP oils in preparation for GF-6 and to address specific concerns such as low speed preignition (LSP) commonly seen in boosted DI engines.

Mobil 1 oils, both in base stock & additive chemistry, are truly state of the art.

Take care,
Gary

higher iron numbers is a common result in UOAs when using Mobil-1.
You can love the oil all you want, but you cant argue with the numbers & trend

LSPI and engine oil affects is an interesting topic.

Moly=good (favors M1)
Calcium=bad (favors GC/BC)
