![]() 2007 wrx 68k miles. TBE and intake, custom tune
Anyone have experience with this oil? I have only done one oil change since I bought the car and they (shop that did my tune) put in Castrol gtx 5w30. I’ve had to add about 1 qt to it since the change (about 4K miles) From what I’ve read, these cars seem to like the higher weight so that’s what I’m looking at. Seem the 5w40 castrol edge is a thin oil so I crossed that off my list. I’m not opposed to using the Rotella t6 but is there any concern with the new formula and it not being labeled with the api rating? It does get cold where I live in the winter, lows will average in the 20s for a few month’s and can get lower. I don’t race the car, just the occasional spirited driving around town. I just want an oil that may not burn so much and my engine will like. Basically I’m between the pp euro 5w40 and Rotella t6. Thanks for the help

![]() Edge 5W-40 is actually a little thicker at 100C than PP 5W-40 (14.1 cSt vs 13.3) but either is a good choice. The PP meets the same specs as Edge 0W-40. MB 229.3/229.5, Porsche A40, VW502, etc. Edge 5W-40 doesn’t have the MB 229.5 but this is all splitting hairs between the three I mentioned.
And you should run synthetic in a Subaru turbo. |

Thanks for the comment. I’ve seen your name on a lot of the oil threads I’ve read recently. So what would be your recommendation based on my application from these Redline 5w30 Motul xcess 5w40 Pp euro 5w40 Rotella t6 5w40 Rotella t6 mv 5w30 Thanks |

Any except for Rotella MV. The reduced ZDDP is preferable for a DIT but not needed with port injection unless you’re trying to maintain warranty on a newer stock WRX/STI. |

Fwiw after 3 different places I ended up at Summit and to my surprise they had Motul oil. I ended up getting the xcess 5w40. It amazing how much quieter the engine runs. I was going to get the redline. I read that the 5w40 was a very thick oil so that’s why I was looking at the 5w30, what’s your thoughts on that? I also have seen that apparently it’s not API certified, is that a big deal? Thanks for the help |

Red Line has a high HTHS so the 5W-30 acts like a 40 weight in the bearings. It’s not API certified due to the high anti-wear additives and detergents. It’s great oil though but probably overkill unless you’re tracking the car. |

![]() Truth about oil: Changing it at the proper interval is far more important than any other aspect (as long as proper viscosity). Especially if your built. I'm looking for an article written by one of the guys over at bobistheoilguy which articulated it so well.
I guess what I'm getting at here, is that you've chosen some pretty good and well known oils there. Any of them will be likely as good as any other of them. That being the case, a strict interval is your best friend. |

![]() Use an OEM oil filter while you're at it. OEM filters are good, even the blue ones everyone hates on.

Oem filters are bottom tier man... might as well get the cheapest filter you can find if you gonna go that route. Watch this video and let me know if it changes your opinion: |

Edit: and I agree... a regularly and/ or more frequently changed filter is the key. Some have the same opinion on oil... that if you change your oil in short intervals, you can run a "lesser" oil with basically the same results. |

If it works for Subaru and it works for Subaru engine builders who am I to complain about an OEM oil filter on a daily driven stock vehicle. |

![]() If you change it at low intervals it doesn't matter what oil or filter you use honestly.
I still run 5w40 t6 and sometimes Mobil1 0w40 with oem filter sometimes Wix. |

Gotta be open to change though. Everyone used to run T6 including builders. Now it’s been lesson learnt and Motul is the choice oil as far as most shops I know of. |

![]() I don't get the bypass thing... If you think about it, it really doesn't matter. The oil could go through the filter once out of every 4 "passes" and you'd end up with the same filtration as it going through every pass.

![]() Subaru blue filters are where its at. 6$ a filter and spec'd for our car. The micron rating is great and you can buy a ton of them on Amazon and shipped to your door.
I dont use anything else on both my STi and my wifes WRX. IAG says to use Motul, but I tried xcess 5w40 in my built engine and it doubled my wear metals after 3k miles compared to my Amsoil 10w-40/0w-40. YMMV. I won't ever use that stuff again. |

![]() I have a 09 wrx with a IAG stage 2 going on 3 years already. I'm no expert what so ever when it comes to motor oils, but I've been using Castrol edge 5w40 for a little over a year (used to use motul 8100 xcess recommend by IAG)I changed my oil every 3k miles no exceptions. So far it's been decent but I might try Valvoline MST 5w40 just because I can obtain it locally.
