I had the Fa20 and in the summer I ran t6 5w-40 and in the winter 0w-40 Castrol edge.
I'm switching to an Ej257, can I run the same oil cycle? Also I read in the manual that if 5w30 isn't available a 5w-40 can be run as an equivalent. Would this be an issue for any warranty claims if I run t6 5w-40?

The manual is odd with regards to 5W-40. It mentions 5W40 conventional (which doesn’t exist) and that it’s only to be used for replenishment. It also does show 5W40 on the temp chart. There is also language that oil of a thicker viscosity is required in hot temps but doesn’t define the viscosity or the temps. Possibly being vague helps Subaru with CAFE credits. The downside to RT6 5W40 now in regards to warranty is that it no longer carries the API gasoline spec. Castrol Edge 0W-40 is API SN. |

I'm from The Netherlands and I'm thinking of what oil to use.
In harsh winters we can have an occasional night of -15C (5F) and in hot summer we can have temperatures of up to 40C (104F) some days. 5W30 is too thin for summer use in my opinion. I was thinking of using 10W40 oil to be able to start it in cold winter days and still have good lubrication on hot summer days. Wat are your opinions? |

In an Outback? You shouldn’t need anything thicker than an ACEA A3 0W-30. |

I have been using the Shell RT6 for the last three years with good results. I wonder if the loss of the certification is associated with extended oil drains. I have noticed that the factory recommended oil drain interval is longer on newer EJs as compared to my ‘05.

The loss of certification is due to Shell being over cautious on phosphorus clogging up cats. Phosphorus is actually slightly lower in the new formula and Shell now has RT6 5W-30 Multi Vehicle. The MV is a great choice for stock DIT’s since ZDDP is lower but the HTHS is high. https://www.bobistheoilguy.com/forum...M_#Post4490450 Quote:

ok so just for clarification, I'm about 1k in for engine break in, and will do an oil change fairly soon.
Rotellta t6 no good anymore (warranty purposes) doesn't carry gasoline spec. 0w-40 Castrol EDGE has gasoline spec, however the grade is not covered under warranty. So rotella 5w30 mutli vehicle is the best bet? |

Here’s an RT6 MV UOA from an FXT:
https://www.bobistheoilguy.com/forum...-km-4500-miles It doesn’t meet GF5 but meets API SN. |

But that's from the Fa20. Idk how worried I should be about warranty claims. For the last WRX I had Castrol edge and t6 based on season, never had issues. I liked 0w-40 Castrol better tbh. my OCI was about 4500.
I'm probably going to run that since it's getting cooler and cooler in NJ at night. I get that Subaru want's to make sure that they are providing warranties on engines/transmissions for the right reasons, but worst case scenario I get ringland and they see I'm using Castrol with the recommended OCI, they can actually deny the claim? |

Oh STI! I know there are some EJ owners running ACEA C3 oils, which have a similar additive package and viscosity as the RMV, but the EJ’s do like thicker oils IMO. As to warranty that’s a tough call. The manual does show 5W-40 on the oil temp chart and also has language that thicker oil is required in hot temps. Personally, I don’t think my dealer would give me any hassles if I were in your shoes, and they have gone to bat for me with SoA on a claim, but it depends on your dealer. I was using German Castrol 0W-30 at the time. Castrol is a light 40 grade and likely shears to a 30 grade in most turbocharged Subaru’s anyway. |

Also, i understand the EJ's like to burn oil a tad more than FA20's. People typically run 3k OCI's. Manual recommends 6k. Should i be OK running around 4500? Last edited by vlad11591; 09-04-2019 at 09:47 PM. |

I posted the RT6 comparison above. Less phosphorus than before but no more gasoline spec. If you’re worried about the 0W there is also an Edge 5W40 and will be fine at 4,500 intervals. It meets one less spec than the 0W40 so it’s good, but not AS good as the 0W40. |

ahhh I checked the manual.. It has to meet one or the other, not both.
So technically should be fine with either the Castrol Edge 0w or the T6 5w-40. Edit- what about this Castrol EDGE? This meets API SN, ILSAC GF-5, ACEA A1/B1, A5/B5, https://www.amazon.com/Castrol-03084...gateway&sr=8-4 It is not the OE spec The 5w-40 is stupid expensive. I'd rather run the 0w-40 at half the price lol. I checked and I can get RMV for like 28$ at walmart shipped. I think the 0w-40 Castrol would be a better oil, however IF THE WORST case scenario did happen, I guess would be denied for warranty? I never really use my dealer for anything lol... Do all the maintenance myself, so I'm not really building any relationships here. Last edited by vlad11591; 09-05-2019 at 11:47 AM. |

Ok so literally spent the whole work day researching..... Note for EJ
GF-5 = not good because its resource conserving and will likely shear to 20 grade. I don't drive the car under harsh conditions, but I do spirited driving on the weekends if I can get out. I'm thinking if I want to be anal about warranty protection- Motul 8100 X-Clean EFE Rotella t6 MV if not.. then I can just run 0w-40 Castrol Edge and call it a day. Meets a slew of specs, including Porsche. Thoughts? |

I run Edge 0W-40 so that’s my pick. It meets the toughest specs in the industry and is cheap. Although X-clean and RT6 MV are both solid choices.

Opinions on what I'm using
I use Rotella t4 15- 40, this was recommended by my mechanic that's been build subaru for good almost 20 years. Thoughts on how itd affects my engine good or bad for it?

Been away from Subaru for a while, but I had to chime in.
I was running Mobil1 15w50 and Redline 10w40 on the factory motor for nearly 2 years. This is in California, but that was all year round. Mornings were low 40s or high 30s in the winter. I chose to get a built motor and make more power with some margin of safety. |

I ultimately went with 0w-40 Edge. It worked so well on the DIT, and I think it will work fine for the EJ. IT's super cheap on amazon right now at 22$/5 qt jug.

If there is an award for this write, you certainly deserve it. my gosh, thats some serious data.
I read and tried the various oils that sounded good for my 08-14 wrx EJ turbo. and had great results with RotellaT6 and my other favorite Motul x-clean. Why no mention of Liqui Moly? My mechanic who does primarily Subies, recommends it. |

2007 wrx TBE with high flow cat, intake and custom tune. No racing
Experience with the pp euro 5w40? The Rotella t6 mv seems intriguing as well. Thanks |
