Actually though... High Mileage Oil
I've tried sifting through the noise but i can't get a definitive answer.
~250k km. Changes every 5k Been using redline 5w30 Have a little ticktick Have a little consumption (quart every 1500ish) should i start using 5w40? should i buy specifically high mileage oil?

Many here use 5w40, Rotella is well liked and available at Walmart. I tend to go for Castrol 5w40 nowadays but have also used Rotella for many years.

Rotella was changed but there is very little difference in the add pack. Just a lot of fear mongering from people who haven’t actually compared the old and new oils. For a High Mileage oil, you’d have to go with a 5W30, 10W30, or 10W40. No 5W30 HM has an HTHS of 3.5 or higher that I can recall and you should stick with a HTHS 3.5> oil IMO. M1 10W30 HM does and any 10W40 will. I’m running a blend of Castrol Edge HM 10W40/10W30 at the moment to try to help with my consumption. You could also try Red Line 0W40 or 5W40. When it comes to oil, there’s no such thing as a definitive answer. Last edited by bluesubie; 07-13-2018 at 07:59 AM. |

I would never run 5w30 in a Subaru personally but then again if I was using a quart of oil every 1,500 kilometers I would be worried about a lot more than what weight of the oil I should use!

i agree with this and i also would never run a diesel oil in a gas engine.

I use Rotella 5w40 because it's cheap and like I said I have UOA's proving it's good.
With that being said I think any high quality oil like Motul, Amsoil, and Redline are great oils and maybe better than Rotella, but not for the price! Use whatever brand you like and can afford but, like has been said already you should be using a thicker weight HD oil in any EJ Subaru and in my opinion even if it was brand new. |

You probably wouldn't run a manual boost controller either. I probably would.....but I probably wouldn't tell everyone I blew my motor because of it either. PS I do, and I haven't....yet but, if I do you will never know |

Red Line 5W30 has a High Temp High Shear similar to some 40 grades. Don’t focus only on the numbers on the bottle. |

Ran Rotella 5w40 for like 50k. Just switched to motul 8100 for the last 10k and car feels smoother but that could be a butt dyno thing. I think both are great. I had a great UOA at 100k using rotella.

Well as far as I know your correct that diesels aren't made to run like gas engines, they're made to stay running! I'm sure that's not hard on the shear strength of the oil ! I don't think it's cheesing out because it's cheaper than Motul or whatever you use. It works for for me, I have UOA's to prove it, and it absolutely does not cause sludge buildup more than any other oil that's changed every 3-5,000 miles!

Smoother doesn't mean better. The feeling you're describing is the internal engine parts moving with less resistance, which actually means they are less protected. They weren't designed for such a thin oil. I would bet your valves were noisier with this oil too. I can't imagine what it was like at startup with such a light weight. You know what has the least resistance? Air. Drain your oil completely and I bet it will feel really smooth for a few seconds. Not very safe though right? You probably even see higher mpg's in doing this, but you would be gambling with your engine. Notice Subaru only recommends their 0-20 for non turbo vehicles. It says what oil to use right in your user manual and on your oil cap. Using something so drastically different is asking for trouble. You wouldn't put 87 octane in your gas tank when it says 91 on the cap right? |

It wouldn't hurt to try. You may also see a slight drop in mpg. |

I meant I changed it to a thin M1 when I was young and dumb, it felt smoother, it wasn't better! |

I recently switched to Rotella, having great results so far. Was a little worried at first and the dude at Advance Auto was trying to convince me that you can't use it in non-diesel cars, but people (including me) like it a lot.
