COMMENTS:

The only unusual find here was silicon, which isn't really that high in the grand scheme of things. Silicon can come from several sources, including dirt getting past the air filter, sealers, additives, or silicone-based lubes used elsewhere in the engine. in the case of sealers, additives, or lubes, silicon is harmless. Wear was fine so we dont think the silicon came from dirt, though we'll keep an eye on it next time. We found no sign of any gas, moisture or antifreeze in this sample. The TBN read 2.3, still some active additive left. Try 12,000 miles next.

Looks very good.

 

[FZ1]

Really good except for the silicon that K & N let in.

 

[Steve S]

K2N filters are not what smart money buys.

 

[simple_gifts]

I don't think I've ever seen an E-tech UOA, looks good; Isn't this car eligible for the 20weight downgrade?

 

[06tC]

Steve S. There is no difference between K&N air filter & the TRD High-Performance Air Filter for my vehicle. The medium used in the filters are the same.

 

[06tC]

Simple gifts. Yes per Toyota, I can use 0W/20 or 5W/20 in the 06 model year. I am currently using Asmoil 0W/20 ASM for this 10,000 MI run. I prefer Motul but my local dealer was closed the day, I changed my oil.

 

[Gary Allan]

I wouldn't automatically blame the K&N for the silicon. I don't see much Al or Chrome that would point to throttle body or valve sand blasting. If it's from airborne sources, I'd look elsewhere for the inlet.

Just my $0.02

 

[glennc]

Geez, I just got down off my K&N soap box and now I have to climb back up on it again.

Gary is absolutely right. This is a 10k oil run starting at 20k on the vehicle. It is very likely that this is still break-in Si, from sealants used in engine assembly. K&Ns and the like can work very well - the trick is that they must be oiled properly and not cleaned too often.

 

[Scuderia]

Motul motor oils do come with a bit more silicone from the factory than usual (around 10 PPM). It's used as an anti-foaming additive.

 

[TeeDub]

New Toyota (and Ford), engines will leach silicon(e) for tens of thousands of miles. All you have to do is look at the wide bead of silicone used to form the oil pan gasket to see why. It took about 50k miles for the Si levels in my old Toyo to stabilize.

In this case I'd say the air filter performance is marginal - the presence of Ni indicates some erosive wear of the intake/exhaust valves.

Based on this data you should have no problem running the Amsoil at least 10,000 miles....

well my FIL would agree (crazy as he is) saying my 2az-fe isn't run in yet at 40,000 miles

 

[REDDOG]

In my book elevated silicon + a Nickel value greater than 1 in any thing other than a new engine is reason to investigate the intake plumbing, etc and question the effectiveness of my air filter. As Gary and glennc stated, however usually there is elevated iron + chromium also. The iron here isn't horrible by any stretch of the imagination, but I'm not really familiar with this particular engine, either.

Other than silicon and nickel looks like this oil + this engine + this interval = good plan.

(Please pardon the tacky math, I haven't had enough coffee yet).

Thanks for posting,

Ditch the Krp & Nasty

 

[OrdnanceMarine]

WOW, still amazed to see all of the K&N bashing going on. Maintained properly the K&N will do fine under most conditions (I wouldn't recommend it for off road use where fine dust is a problem). My previous 2000 Honda Accord's first UOA at 101,819 on a 8690 mile run with a Honda oil filter showed Si at 10 PPM. This car has an aftermarket AEM cold air intake that I installed in 2001 somewhere around 15000 miles with a K&N cone style air filter on the end of it and situated pretty close to the road. To top that off I live in an area notorious for blowing sand/dust/dirt. Based on what I was hearing here I was expecting to see Si at 50 and wear metals at 5X universal averages but that just wasn't the case.

You need to start reading a few UOA's where Krp & Nasty is used then you will change your mind.

and look at a few air filter tests.
I won't touch one with a barge pole having used one years ago in a high dust environment.
Sort of Ok race filter, that's about it, and R2C blow them away for race use too.

Actually I take that back, they aren't any good for racing either.
A mate is a filtration engineer and he has data from an F1 engine manufacturer that used them and lost engines at a GP thanks to sand ingestion.

 

[06tC]

Thank you all for your replies. I will have the Asmoil 0W/20 ASM UOA done shortly only have 5k more to go.

An 06 civic SI owner here with 23k of documented blackstone UOAs using a K&N panel filter showing great filtration, cleaned at the beginning of one 14.5k mile run. I'm running it continuously now up to 30k before cleaning it, to see how silicon does with it from 15-30k of uncleaned usage.

They can do the job, when used right.

Makes sense.

I can't remember how many people buy them, but don't clean and oil them correctly.
