Default HELP!!!!!...question on what oil to use

Hello all. so I switched to Rotella t6 about a year after owning my 05 sti, because a lot of people responded saying that that is the best oil to use because of the engine running hotter, or maybe it was because of how that oil adheres to the internals of the motor.
anyways, I just finished watching a youtube video and someone with a 06 sti was using Rotella t6 and stopped because (I can't remember which he said) he said it stained the motor or scarred the motor. so is there a better oil I can use? my 05 sti has just bolt on's and a tune, tuned rich as requested to help the motor last as long as possible.
so yeah, is there a different 5w40 oil, or maybe just a completely different weight of oil that I should use. and then having used it for about a year, is there anything I can do to undo what has happened to the motor, if in fact anything has happened?

RT6 is just fine. If you are worried, do a blackstone oil analysis with TBN. Read the stickies in the service/maint forum for oil selection. Youtube is for cat videos, not oil analysis.

seriously? another oil thread?

there should be some algorithm that if anyone makes a topic with the words "help" and "oil" in the same topic, it logs them out or bans them or something. this is getting rediculous.

there are literally thousands of threads on oil topics. go search. stop playing candy cruch while you poop and maybe read something.

That video is nonsense. It is not the oil's fault. T6 is fine to use but it's certainly not the "best" oil. Here's a great comment on BITOG:

"I don't understand the fascination with T6. I think people see it's "add-pack" and get a chub, when that is only one small part of the much bigger picture. There's a lot that doesn't show up in a VOA test. EDGE 0W-40 seems like a no brainer".

Look for an oil that meets these specs:

ACEA A3/B4
API SERVICES SN / CF
BMW LL-01
MB-Approval 229.5
Porsche A40

These "german castrols" seem widely available now, at least here in CA (at walmart). They are labelled "european formula" on the bottle, and priced similar to M1 and other synthetic motor oils.

Pick one oil and stick with it. The dynamic range between the very best and the very worst isn't enough to justify wasting money or time. As others have said, RT6 is perfectly fine. There are many other alternatives, it honestly doesn't matter unless your car is tracked. If you want your internals to be clean, perform an oil flush every oil change using a detergent pour-in additive. Oddly enough, I don't use RT6 but it has nothing to do with its quality. For me, RT6 is actually too expensive relative to its quality. If you still can't make up your mind, read this to satisfy your oil porn needs.
