How many total miles are on this van? The AL seems high.

 

[buster]

Si is high which may be causing Al to be high. I'd check your air filter. Otherwise, looks good.

 

[Donald]

+1 on high silicon. Look any which way around the filter and housing, hoses.

 

[OrdnanceMarine]

I know I'm a broken record, but check your air filtration. That Al is high and the high Si points to dirt entering at some point unless you have another reason for the increased Si (valve covers removed, etc.). From there I'd change this oil out right away if you haven't already and then start sampling during your next OCI with a vacuum pump or other means to pull oil while still leaving it in service.

The van has 90,xxx miles on it.

It also has a K&N filter on it the last 10,000 miles.

The oil filter is a stock Toyota.

There's your problem. The k&n air filter. They flow great,at the expense of filtration.

 

[webfors]

run oem or fram paper filter and you'll see single digits Si and lowered Al/Fe. AFE 0w30 held viscosity well again. I like an oil that does that

 

[gpshumway]

Yes, ditch that K&N filter. OEM, Wix, Donaldson (Amsoil), Purolator, Fram, all will do a much better job.

Great to see AFE 0w30 holding up so well.

 

[Cujet]

Maybe the K+N is responsible. However, I run a K+N in my Jag, my F150 and my airplane. None of them exhibit high Si.

Could be my location is "free" of sandy air. Or it could be something else.

In the past, I tried using thick grease downstream of the K+N in an attempt at catching dirt that passed through the filter. Never got much.

Reusable filters get a bad rap, but not for the right reasons.

The upside of any "reusable" filter is cost savings.
The downside is that they are very susceptible to variation in set-up.

Too much oiling affects the MAF and can cause drivability issues.
Too little oiling will not trap dirt appropriately.
Too much oil in one area and too little in others, all on the same filter, can result in both problems at the same time ...

They work great, when they are properly set up. That is very hard for the average guy to do.

The results are telling here; the Si and Al are up because the filter is not doing it's job.

The filter might be "capable", but it's not currently performing to it's full potential. And regardless of what "might be possible", it's more important to focus on "what is really happening".

Either get it right, or live with the consequences.

I think you and dnweton3 touch on an important point in that reusable filters leave a lot of variation to the user that just isn't present with a single-use filter. I live in a downright dusty/sandy corner of the world and had a oiled K&N on a past vehicle and had great results. I was probably on the side of slightly over-oiling it but it was not a MAF equipped vehicle so there was no harm in erring on this side. Human nature is that we tend to believe we will do a better than average job so we tend to ignore the evidence and think we won't have the problems that the "average" guy has. May or may not be true.

On my 4Runner there are no practical gains to changing from the OEM style filter and I do suck up a fair amount of dust, especially when I'm behind someone during off-road expeditions so I stick with the OEM style (think I've got a Purolator in there right now). On my Si there are definite gains to modifying the intake system since it's a different breed of cat but even here nearly everyone has gone away from oiled filters to oilless reusable models.

I would stick with a standard filter element for this application.

I also opted for the K&N filter years ago on my Sienna. At the time I thought it was an economical option and would filter as well or better. After the many comments questioning this type of filter, I am having second thoughts. I did do a UOA last August on my Sienna which showed Si at 22, Fe at 12, Al at 8, 9k/139k, but over 12 mos. I intend to do another UOA with the next OCI and with a cleaned filter.

I probably don't attend to the filter frequently enough (~30k or 3yrs). How often do others clean and re-oil their filters?

With the K&N filter being new, it should have been performing well. Is your driving area dusty?

 

[LeakySeals]

Did PA have an early snow storm this year?

Mine have been installed for nearly 6 years; I've cleaned each one twice now, so that works out to every 2 years, which is about every 22k miles, on average.
