K’s are getting up there but not high enough to really worry just yet. 

Fully synthetic is the usual recommendation for these. Castrol Edge 5w-30 or 5w-40 are what I've always used.

should i change the oil asap or just change it to 5w40 next oil chnage?

I would, i've had two BP legacies, one N/A one that had 270k and my current turbo one has 240k, and both are run on 5w30 (Fuchs Flex 23 to be precise). However my WRX which has only 220k on it runs 10w40 (Penrite HPR10)

 

HOWEVER this is a general recommendation. Thats because it depends on how worn certain parts of your particular engine are that were caused by many factors from before you even owned it. Thats why i've ended up using two different grades for essentially the same engine on my cars.

 

If you do try the recommended 5w30 it would be worth checking the oil level regularly (say every fuel fill for a few weeks, and then maybe once a week if everything seems fine).

 

If you notice the engine consuming oil, then it would probably be better going back to the thicker grade next oil change, but if you see no change after 5000k or so then you should be fine to continue checking the oil as you would normally, And then you can continue on using a oil that would allow your engine to work more efficiently.

on your wrx do you use 10w40 semi or full synthetic? I was looking to get the penrite 5w40 full sythn hpr5.

The fully synthetic one, you wouldn't want to use a mineral oil on something like this.

 

Hpr5 would be fine, as it uses what penrite call "extra 10" so it should behave like a 5w30.

 

And it's on sale at the moment at repco iirc.
