2011 STi won't give accurate oil read-out.

[SD_GR]

I'm new to dealing with the vehicle's oil situation myself, so if you would continue to have patience while helping me I'd sure appreciate it!

Okay so far, I'm nervous and unsure on what to do. I don't know where to get a UOA, or even what it consists of.

I need oil bad so my plan rite now is to borrow my ma's car, go over to advanced autoparts, get some rotella t6, then go to subaru grab an oil filter, then a crush washer. What I'm wondering, is do I need to use a subaru oil filter? are other companies better filters?

Since your car is under warranty, follow the owner's manual for oil viscosity, specification, and change interval requirements. You do not need to use Subaru filters. However, keep any and all dated receipts for future warranty use.

Look at Blackstone Labs for UOA info. However, since the car is under warranty, follow the owner's manual anyway as stated above.

car is no longer under warantee. I have a retune and an exhaust.

How is a 2011 no longer under warrenty?

You are still under warranty until 60k miles (drivetrain at least). You MAY however, be denied a warranty claim if it is deemed that your aftermarket parts caused whatever issue were to come up. Very big difference here...


As for oil, use what you've been using. I do not believe however, that Subaru supports Royal Purple. Don't use that.

Spiros has some good advice here. I use Blackstone for my UOAs and I like them a lot. They give you a nice write up to either instill fear in you or make you feel a bit better about yourself - much like the people that write the sayings in fortune cookies. Basically you take a small sample when you change your oil, send it to them along with $20-25 and they will tell ya how your oil is doing after some lab tests.

Your car certainly still is under warranty. As mentioned, the manufacturer may not honor a service request due to modifications or the time of day. That being said, not following their oil advice is always a good place to point a finger for any issues down the line.

I picked up a 6 pack of subaru oil filters (crush rings included) off of genuinesubaruparts or something along those lines. I don't use the crush rings anymore, however, as I use a furmoto oil valve to make life a bit easier (flexible tubing is fantastic stuff when it comes to cleanliness).

Damn, that furmoto oil valve is a great idea. I'm gunna order one tomorrow!

I have one for sale if you want it.

As for oil, I recommend Motul. It's 100% synthtic. Yes, it's pricey.

How much do they cost? I couldn't even find one for sale brand new, and from what I know of you, you seem like a good guy, I'd most likely be interested.

And where do i get myself some Motul?

And I just hit 30k miles, is it time for tranny and diff fluid change?

If your using the "German Castrol" you won't find a better over the shelf oil that can be had with a filter for 30 bucks on sale at Auto Zone or Advance Auto. That's what I've been using since 1000 miles and have no complaints. I have also not seen a single bad uoa with GC.

[sportsman]

If i may ask. What happened to your first engine??

[MainFrame]

I always check both sides and go by whichever is lower (and do it twice). If you think about it, when the dipstick is submerged in oil it is possible for it to creep up one side or the other, but it wouldn't make sense if an area that was submerged came out without oil on it.


As far which brand to use, Rotella T6 used to get really good results due to its high zinc content. However the T6 you buy now days has been reformulated to a low zinc formula, presumably to preserve catalytic converters. In fact, basically all common store bought oil has gone to low zinc formulations now.. so you're kind of SOL unless you're wanting to spend money on a high dollar oil.

For what it's worth, I still use T6, just with a zinc additive.

Thanks, man. PM me if you want it. 20 bucks. You can order Motul online.
