Hey all,

Will be fitting gauges soon inc oil temp/pres so when fittin the sandwich plate im gonna do an oil change.

This will be my first change, im aware of the procedure etc.

I was thinking of using mobil 1 and i want to know what grade i should be using?

What are youre thoughts/recomendations etc?

thanks

 

Depends your bhp!!! Standard uk normal 10/40.. Uprated engine and STi etc mobil 1 15/50

 

sorry forgot to mention that,

its standard at the mo except exhaust,

will be taken to approx 320/330bhp pretty soon though.

thats gonna be about it

 

As said above. If standard STi i'd go with mobil 15/50 as well.

 

If its an oil question it wont be short

 

what do you mean Moray ?? !




heh heh

 

i was using this in my sti type r and was advised against it by a very reputable place here in ireland..was told castrol rs 10w 60 is a far better bet..so there ya have it..legacy sti my sti type r is for sale at the moment, in the trader tmrw if u know anyone interested

 

Now look what you have started...the dreaded oil debate strikes again

 

okay well, someone else add ya 2 penneth worth then

 

My legal advisor has told me that I am on no account to post on an oil thread.
The potential for litigation is frightening so he says.

 

so is that a vote for the mobil 1 or the castrol?

lol

 

i've been told by a Stealer that as long as it's fullt sythetic then you shouldn't have a prob, so i put Castrol RS 10/50 in mine all is well, but then it is standard so why shouldn't it be? have mods planned and will still use this oil i think, a compamy like castrol isn't going to produce cr*p imo.

 

My dealer told me that Subaru don't recommend fully synth which is why they put in semi synth oil.

 

dealer i spoke to was in germany? wonder if they are different over here

 

One local dealer uses Magnatec (10/40 semi) while the other uses Mobil 1 (0/40 fully synth.)
Maybe they have similar oil debates as on here too...

 

FFS i just wanna do a bloody oil change!!!!

are we pretty agreed that 15/50 is what i want?

 

I've got Silkoline ProS 10w50 in mine, running about 330 BHP

 

Yep,If your gonna use mobil 1 make sure its the 15/50 and not the 0/40

 

Out of interest, whats wrong with 0/40

 

Too thin!
10/40 10/50 is the way to go.
Do a search... and have lots of spare time to read all the posts.

why not what your owners manual recomends....my blobeye recomends 5w30 prefered as long as meets correct spec.. does not mention whether fully or semi though

 

While you may think that Subaru know best, stripping down an engine from a car that has only had main dealer care may change your mind.

Now Subaru recommend that you go with a thicker oil if you are using the car in higher temperatures or with heavy use most of the time.

I would only use a fully synthetic Ester based oil, which would be something like Millers CFS, Motul 300v, Castrol RS, Silkolene Pro and similar oils (in your preferred grade). We use Millers 10/40 for standard cars, and 10/60 or 15/60 for modified cars including my own car.

I'd go with Silkolene PRO S 10w-50 if it's heavily modded.

Cheers
