Default Oil for 2011 sti

I know this has be answered over 9000 times but I googled all of them and can't seem to find a "REAL" answer just more sarcastic comments..

I have a 2011 sti.

Used M1 for about 2.2k now otherwise used subarus oem oil.

Gonna do oil change next week when i hit 3k

I'm trying to keep it to local oils i can go to like an advanced or pepboys or walmart and get it but if it comes down to it i'll buy online.

If i have to buy online I would buy motul, assuming this is good?:
Motul 007229 8100 Eco-nergy 5W-30 100 Percent Synthetic Fuel Economy Gasoline and Diesel Lubricant - 5 Liter : Amazon.com : AutomotiveMotul 007229 8100 Eco-nergy 5W-30 100 Percent Synthetic Fuel Economy Gasoline and Diesel Lubricant - 5 Liter : Amazon.com : Automotive



If I don't have to buy online what can I buy?

I talked to my tuner and he said Rotella t6 is good but since I have a catted downpipe it can start clogging it up.

You'll probably get the use search response. I'll throw one out there, do a search for oil filters, since that may be the next thing you ask.

Speculation is that the Subaru Oil is Mobil 1. Steer clear of the "standard" 5w30 Mobil. Your engine will thank you.

Motul, Amsoil, Rotella T6 are recommended. Redline is good, but there's debate on that as well.

Weight can depend on where you live. I'm in NorCal, right now it gets pretty warm and with a 42 miles drive to work and home, with boost some good boost here and there, I like to run Rotella T6 for the 40 weight. Re: the cat, the additives in the Rotella for diesel, zinc I believe, is far less then it used to be. A lot of Legacy GT owners and I'm sure WRX/STI run Rotella with no issues. If you are concerned and in a warmish climate, Amsoil/Motul 40 weight.

If you are in colder temps say below 40's, 0w30 or 5w30 would work well, try Amsoil, Motul or Castrol Syntech 5w30 Euro formula (Made in Germany).


Has your tuner actually seen the damage caused from Rotella, or just from what's been debated and/or the additives? Just curious if there is some solid evidence.


And while we are at it, drain/fill your tranny fluids frequently - every ~30k

Amsoil or Motul are both damn good products. As stated above, if it's a warmer climate you might want to change to 10w-40 (I run Amsoil 10w-40 full synthetic) and if it's colder stick to 5w-30.

I suggest calling a couple people like MPS/COBB/Etc. and ask what they use.

I'm curious as to where you heard the Subaru oil is actually Mobil 1? Based on what I have seen, its manufactured by Idemitsu? I'm not trying to start anything, just curious as to where this came from? I don't pretend to know much about oils, but I am trying to learn (I am going to start using Rotella T6 very soon).

Rotella T6. Your tuner is an idiot if he says your oil will clog your DP.

The Motul Econergy 5W-30 has an old school API SL anti-wear additive package (ie more ZDDP), but it is thin at 100C. A better Motul oil, especially if you are modified, is Motul X-cess 5W-40. Here's a 9,000 mile used oil analysis on it.

Rotella T6 is a mixed fleet gas/diesel oil that meets API SM specs for gasoline passenger cars. There are plenty of REAL answers here and all over the web. You're just zoning in on the silly posts.

Red Line is excellent oil and the Subaru oil is made by Idemitsu. Mobil1 0W-40 is a good choice and has only slightly less ZDDP than RT6. If your are concerned about cat clogging (you should be if you're burning more than 1 qt every 1k miles) Motul X-clean 5W-30 or 5W-40 are mid SAPS oils with lower phosphorus levels but a nice shot of zinc. How much oil do you burn?

Those are the FACTS. Basically you don't want to run ANY oil that says Resource Conserving in the API donut on the back. That includes most xW-30's unless it's a racing oil or it meets Euro oil specs.

Thanks for clearing up the question concerning the Subaru oil. I was fairly certain it was made by Idemitsu but wanted to confirm.

As I mentioned above, the issue is not zinc it is phosphorus. And cat poisoning (not wear) from phosphorus is only a concern if you are burning a lot of oil.

How about German Castrol 0w-30. Thought that was another proven choice.

Mentioned in 2 and 10, it's what I've been running in mine. My UOAs have come back good. I'm doing 5,000mi intervals. It is more expensive than T6 though. I can usually find it on sale.
