ok here we go... Royal Purple 10/40 - 3.5/5 Castrol Edge - 10/40 3.7/5 Motul Synthetic - 10/60 3.7/5 Fuchs Synthetic - 10/40 4.1/5 I rate the oild based on Price and performance.. The royal purple, did nothing for me, burnt quick and was the most expensive. The Castrol edge is also pricey, but lasted the 5000k's and still had more to go, but once again, is very pricey. FUCHS - Cheapest of all by far (I mean $20 cheaper!), doesn't burn, no bad engine sounds, and still holds itself even after a good beating, I gotta say, if you haven't tried it, give Fuchs a go.

OEM at the moment. but will be moving to Motul next service as I don't plan on taking my car to Subaru to get bent over and reamed for the 100K service.

Magnatec, Its last the 15k since I last serviced the POS. Costs sweet FA too.

[CRUISN]

Mines getting done tomorrow. Might try the fuchs 10/40. Put fuchs in the missus car, all good.

I am using Pennzoil synthetic 5w50 and its been great. drop it out after 10K Km and it still looks as though it has plenty of life left in it, Plus I get good trade prices on it

Royal FTW! nuff said. Search on the ozlib I posted a report of oils done way back on approx 20 diff oils, if I ever find it I'll post it up

Wouldn't know, never change my oil, what is it anyway.....oh hang on, you mean the Penrite semi-synth, oh yeh, subarus love semi synth for those who might not know, it stops foaming in the lifters which prolongs life and stops tappet noise which subarus love to do, especially old RS's, they suffered from oil foaming big time. End of lesson.

Magnatec 10W 40

[Joe]

your supposed to change your oil??? i just put in extra virgin olive oil and it works great for the last 50k

[d_generate]

My mechanic told me to use 10/60 Castrol Edge in my STI motor but 5 or 10/40 in my WRX motor, this was from run in on both of them having just been re built, reckons the STI needs the thicker oil as it'll get a harder time & he's building high performance Subi engines every day at MMS.

[Ardorpes]

So after reading that, i have no idea whats the best for my outback :S Everyone says diff ones are better...!

[RX25SE]

Mobil Formula S2 10w-40 semi synthetic in the mighty 2.5 n/a GenIII.
Changed every 5000kms

End of lesson.

Are these the ones that used to suck air in through the oil pump seal, aerating the oil so the lifters tap?

End of lesson.

also the cause of big end bearing failure in rexy's, oil foams at the crank and all the heavier stuff just moves to the outer case (cosworth cranks are specially engineered to minimise foaming and almost eliminate it)

anyway

2.5L DOHC EJ25D & 2.2L SOHC EJ22
both run Nulon HI Tech 10-40
My gen1 has never been quieter, i ran castrol GTX3 for a while but it lasted nowhere as long before both cars got noisy
Nulon has my vote for everything lol and its Aussie

[Ericmcg]

I use Castrol Edge Sport 10w-60 fully synthetic, changed every 5000ks, comes out clean and engine runs silky smooth.

[scottyb]

i use whatever 10-40 the local sprints has on special. when i actually have a decent car il probably use fuchs.

[lebspec_liberty]

Penrite HPR 10

[Evil_VZ-T]

Penrite HPR10 In all the Subaru's that i work on. Penrite HPR5 in the STI's with AVCS Penrite SIN0 in The Mitsubishi Lancer Evolutions and the Built Subaru Donks. never had a problem.
