or your preferred method. the subaru TSB for cleaning valve deposits involves spraying a PEA-based cleaner into the intake manifold via a vacuum line or MAP sensor hole, PEA-based fuel additive in the gas tank, followed by an italian tune-up.

I did this last time I had a random misfire code and it's been gone for almost 20k miles now, all for the cost of a can of GDI valve cleaner and a bottle of fuel system cleaner.
Good lort, I was not expecting to spark up some controversy 
Looks like the general consensus is clean, full oil, and monitor frequently. Looks like Mobil 1 ESP 5w30 is the easiest to find here, or order from Walmart easy. Might order the 3 5qt pack from Walmart and use it in the WRX and Tacoma with the little 4 cylinder turbo.
Dumb as it sounds, despite the AWD system I won't drive it much in the winter mess we get. It will see most of its miles in the warmer months.

The short time I owned a WRX ( Traded for a first year Hellcat ) I used Idemitsu and that older Japan made OEM Subaru filter but around 2014 / 15 Subaru changed that Japan made filter to Fram made OEM in the USA market, I then started using WIX filters with the same OEM by-pass PSI spec. I'm still a fan of Gastonia NC made WIX!
My buddy used Rotella in his ( seen better days 2002 WRX) not that it was the oils fault as that WRX was a modified dog but my buddy only got 10K miles total from purchase day to selling to the junk guy as he lost an engine. He paid $10K and got 10K miles,,, $1 a mile and the engine went BOOM!
The day he purchased that car I noticed his factory air box K&N was completely deteriorated to what I would call mush! Not the filter area as much as the rubber frame, he had to toss the K&N ( I have used K&N 30 years ) I have never seen a destroyed K&N and I wondered then if the filter is that bad what about that engine?
I have zero problems with my WRX, Cool car!

This is BITOG friend, if someone started a thread entitled, "Is water REALLY wet???" there would be BITOG spelling expurts coming out of the woodwork to argue with every last little trivial nuance.
I call it the sickness of correctness and it has infected much of the internet and society.
this thread is downright cordial tbh. wait til you ask about which filter is ok to use!Good lort, I was not expecting to spark up some controversy

I'm sure the 5w30 is a fine oil, and it has similar stringent approvals, but many here favor the 0w30 due to its ester content. Same price. I would use it in both too.Good lort, I was not expecting to spark up some controversy

this is the real shame. a subaru on winter tires is like driving a supercar in the winter.
Maybe once I get some new tires. The Hankooks that are on there really don't get good winter reviews. That and all the salt. I guess I could Woolwax the underside when I change the rear diff and transmission oil.
fair, it is terrible working on my car. I should probably do krown or fluid film but the real killer is the jesus bolts on the knuckles. nothing stops corrosion getting in, any suspension job is a nightmare.
Truth! I love smashing around in the rare snow we get on the A/T tires
I see those temps too sometimes. I forget how high it got when I drove to FL but it wasn't supper high. Maybe 230 max? Maybe? I have the 2018 Legacy with the 2.5. I've been using Mobil 1 Extended Performance for 90% of its life.
I finally saw some higher temps with my 2019 Impreza. Maybe 225. Usually I have problems getting to go above 212 even in the summer. But after this latest change and longer highway drives, I have been seeing ~216. Been using PP the last few oil changes. Was 1 interval of Valvoline Restore and Protect before that then PUP before that for a few. Maybe even M1 before that but I would have to go look at my mysubaru account to confirm. I'll try and see what I get tomorrow. Have a gig about 25-30 miles away. And next weekend is maybe 70-80 miles away.
