Had my Impreza for a week or so now, just wondering what oil and filter people use for them? It's a 53 plate BlobEye WRX remapped to 280 bhp.

Thanks in advance guys

5/40 fully synthetic should be fine I use fuchs or shell helix which is on offer at eurocarparts at the min if you can use a genuine black subaru oil filter from scoobyparts etc cheers Phil. ..

Oil is an age old question and everyone seems to voice different opinions. I use Miller's cfs 10w/40 on my classic running 278hp at 169k miles. I've used shell helix before.

I'm running a 2003 blob WRX, 315 BHP , I have millers CSF 10w/50 in at the min :) 

OEM subaru oil filter 

HKS pink oil filter with Motul Sport 5w/40, Blobeye STI 300bhp!  :D

shell helix and subaru black filter,used in my bug,blob and now hatch.

Milers quietened down my piston slap compared to the fuchs oils,

I'd buy what ever brand you like/think works best see how it goes and if it doesn't seem that good next oil change try something different

5W/40 Mobil and genuine filter.  5W/40 seems to be most popular that Ive seen personally but brands do vary widely. 

Do any of you use 5w40 even if the manu suggests 5w30?

My manual says 5w30, bit many sites suggest 5w40. Is there much of a difference?

I use 5/40 in mine Tom and was recommended to in my forester too

Depends on what oil you use I know that there's hardly any difference between the milers 40/50 oils as I was gonna go upto a 10/50 was told there's no point, as the makeup of the oil is pretty much identical.

Speak to opie they'll let you know what's what

Semisynthetic 10w/40 shell and check it every month because the turbo uses a little bit of it.

I use 10w 50 fully Synthetic as it's modded on the bug and 5w 30 on the standard blobeye. I agree to check it though if you drive it a bit. Biggest killer to scoobs is starving it of oil.  

 

Import car parts I use for my filter but did get a Bosh one from Halfords last time with club discount was cheap. also can use OpiOils to get oil from. As for brands  I will leave you to choose what you feel is best for you and your car :) 

Millers 5/40 in my 2003 WRX blob, mapped to 280. Opie oils are great for advice. Genuine black filter

Just purchased a service kit from scooby world 5w40 fully syn. There prices ain't to bad.

5W30 Shell Ultra Helix Professional fully synthetic and Subaru Black oil filter.

Millers 10W40 here, recommended by my garage who use the same in all their imprezas and evos! Not sure what filter they put on it, will find out next week when I'm lying under my car trying to reattach a plastic gaurd

Got the same job here. Managed to get 2 genuine splash guards off a breaker. Problem is whoever removed them first time has sheared one of the bolts that hold them in place at the back grrrrrr!!!

I order a major service kit from scoobyworld. Previouse owner said cam belt been done. When servicing found a HALFRAUDS Filter and all plugs looked like the electrode had burnt away. Defo gonna check the cambelt

changed my opinion on oil other last couple days,here is what i mean,all the subarus i have had i have always used shell helix and was happy with it,when i bought this blobeye i gave it a oil change as i do with all my car so i no its done,so the oil as been in about 2 weeks now,today i was finishing doing my gauges and i was going to use a sandwich plate for oil sensors but not now,diffrent story that,but any way i decided to change oil again but try something diffrent,so decided on castrol magnetec 5w/30w 5A fully synthetic and have to say what a diffrence it has made,when your under bonnet the car sounds quieter and much smoother and when driving it seams much smoother,before if i was coasting down hill in 3rd at about 3000rpm the car sounded rough no it sounds nice no bad sounding noises and even the noises from the turbo which i was told was the turbo on its way out have gone,car picks up lovely now,the big test will be in 2 week when i change oil again to see if their is a diffrence in the condition of the oil to the 2 weeks runing shell helix which was black when i drained it,so will let you no in 2 weeks.oh and the magnetec was cheaper to buy 

I use Millers 10w/50 fully synth on a prodrive blob STi running 320bhp. I'm going to use 5w-40 in Winter and 10w-50 in Summer. For a standard STi/WRX I would use 5w/40 all year round.

oil is hotly debated so shall leave that be, as far as filter, genuin subaru one everytime even on high power builds

I used to run millers

I just got mine from OpieOils, Millers 10w40 for ~320hp WRX blob and genuine filter. Will be changing it over the weekend :)

I use shel helix ultra 5-40 on my forged 2.5 sti and a blueprint filter
