This is my third UOA through Blackstone and I am wondering if I should be concerned with the high iron readings. Any ideas as to what may be causing this? I pulled up a few UOA reports via the search function for other 1GR-FE engines and don't really see the iron levels any where near where mine are.

I don't tow or take my truck off roading. Just my daily commuter to and from work (about 35-40 miles each way). If it makes any difference, the transmission is a 6 speed manual. Any insight would be greatly appreciated!

Yes, you should be concerned. Going another 10,000 and checking back is bad advice.

What did they say about the high silicon reading on your first sample?

Looks to me like something got in via the intake system and is now wreaking havoc inside your engine.
 
Looks like it ingested a pile of silicon at some point, which has caused the elevated iron. I would do a few short OCI's to see if you can flush it out before trying to extend them again.

ONLY on the Iron parts? I don't think so...

I think it's the Pennzoil Platinum wreaking havoc on the internals

High Silicon levels are from the factory fill @ 1,000 miles. Come on man, it did not ingest a tube of silicon.

Dirt shows up as silicon bud

But I didn't realize that it was the FF (not enough coffee in me yet!), which would likely be leaching from sealers and gaskets.... Unless somebody spiked the crankcase with some dirt

I'd be more concerned with insols 'appearing' to track higher coupled with the oil thickening up.

IMO, 7,500 max should be the goal with PP in this app for now. Get a better oil filter, go to 7,500 and re-sample.
 
Definitely not in family with other 1GR-FEs. See my post from a few days ago with this engine and similar total miles on the odometer. Interested in figuring out what's going on. I ran PP 5W-20 with some light towing, moderate 4WD in the high Sierra Nevada and around the Mojave Desert where I live and short trips galore and saw single digits.
 
Thank guys. I've been using a Puralotor Pure One oil filter since I got the truck but welcome to other suggestions if it will help the situation. I'm going to drop my OCI to 4500 miles to see if it makes a difference in the next sample. Also thinking about experimenting with a different type of oil for the next fill in hopes that may help things as well.

Step one: Learn the difference between silicon and silicone.

PP is a top rated oil. Are you honestly going to make yourself believe it is the oil?

Like it or not, you have a problem. Is this not the purpose of doing an analysis?

Did you put on or ever install an aftermarket intake system or air filter?

I ask again, what did Blackstone say about your silicon on the first sample?

The numbers are supposed to DROP, not go UP!

Thanks.



I have personally done all the oil changes.

No aftermarket parts or intake installed. Everything is bone stock.

Here is the report from Blackstone from my first oil change (factory fill) about the high silicon levels:

"The high wear metals and silicon are not unusual finds in the oil from your new Toyota. The
wear is high due to break-in of new parts, while silicon, which is higher than we usually see, is from
sealers and sand-casted parts. Universal averages show typical wear metals for oil from this engine
after 4700 miles use. We expect your engine will look that good or better in two or three more oil
changes. Toyota engines tend to wear very nicely, and yours will too once it's past wear-in. Check
back to see improvements."

Keep using the PP and P1 with confidence, you will be hard-pressed to find a better bang for the buck. That combination should EASILY take you to 7500 miles in your application.

Shorten the OCI for a couple and see what happens.

No way that oil or filter are to blame.

Pure One's are excellent filters and exactly what I'm using on my 1GR-FE (I use the slightly longer than stock version), my Civic Si and have used on all of my previous vehicles for going on a decade now.

Pennzoil Platinum is excellent oil and there have been too many to count instances here on BITOG of consistently excellent performance from it.

I concur with you dropping the OCI to 4500 miles but instead of just dumping the oil then you might consider getting a little vacuum pump that you can pull a sample through the dipstick with and send that in and see where you stand before you dump. If the results come back as good as the other 1GR-FEs we see here then I'd keep the oil in and sample ~2,000 miles later and see if all of the sudden wear is accelerating (though I doubt it).

I don't see silicon being a problem currently as it's really low considering how long you ran this oil. There's also no sodium or potassium so it doesn't seem like coolant is getting in there.

Do you idle this engine for more a few seconds from a cold start before you drive it? Do you spend more than a few minutes idling it at stops? Do you move this car in and out of the garage or some situation like this where you start it for a few minutes and then shut it down over and over (which could be throwing a lot of water into the oil and when it condenses it's oxidizing)? Not things I suspect but definitely want to get those off of the table.

There's a problem here and it seems worth chasing down, especially before the warranty is up (5year/60k).
