2004 Impreza WRX STI 4300 Miles Redline 5w30 W/LC & FP

[2004_STI]

Lead seems to be high in this UOA. LC was 8oz at beginning and 1 oz every 1k. FP was also added at the recommended dosages.

Blackstone actually commented on certain synthetic base oils attacking the bearings. I was curious if they ever noticed that RL shows higher Pb, for whatever reason. I'd use Mobil 1 in this engine.

Can you make the picture smaller? It it way too big for my 17" screen.

Typical Redline. Good numbers except for lead.

Subaru approves a wide range of viscosities for this engine, correct?

I'd run M1 0w-40 without an additional additives for an OCI...

Amsoil works good in Subarus.

If they are saying that in his comment, and he used red line, most likely they are hinting at something.

Wow thats a lot of Moly. Is that from the Redline or the LC?

It's from the Redline.

I don't think the LC thinned out this oil to much during this interval.

I think the lead is the gas station I use. It was high in my TSX as well.

Did you run RL in the TSX as well?
Hondas show a lot of lead when RL is used.

 

[Last_Z]

Was the previous OCI redline as well?
If so, you "might" want to discontinue using RL. I'd be all over M1....I just couldn't sit there and watch RL clean this much metal off my bearings.
