just wondering what anyone would recommend regarding which engine oil to use?
currently using 5w-30 but im not sure if i should be using maybe a 10w-40?
car is running at 400bhp and seems to use oil when giving car some stick?

cheers

 

Which MY?

 

06 sti

 

Not sure what the Subaru recommended is.

But I'm sure any of these would be okay:-

5W-30
5W-40
5W-50 (if there's such a combo?)
10W-40
10W-50
15W-40
15W-50

If it was me, Id opt for a 10W-50 or Motul's 300V Competition 15W-50. Don't use an oil with a 'hot' weight of 60, though!

 

Subaru put out a bulletin some time ago recommending dealers now used 10W40 for all newage subarus.

My recommend for a modified newage making 400 is Millers CFS 10W60 or Redline 10W50.

 

I use Millers CFS 10W-40 from ZEN, for the record (that's in a Classic though)

 

No need to go thicker then SAE40 on an 06 model.

We would recommend 5w-40 synthetic for all year round use.

Guy, just a quickie...

Why are New Ages recommended 5W-30 or 5W-40... Whilst the Classic 'common' weights seem to be pretty much: 10W-40, 10W-50 or 15W-50? What's so different about their respective engines, or whatever?

 

Generally its because the old classic ones are for lack of a better word often more tired (engine tollerance wise) and are happier on a slightly thicker grade, of course this does not apply to all cases.

Oh yeah, stupid me - logical. I should've worked that out for myself.

Sorry dude.

As you were...

 

would a old classic be ok on 5w40 though ?

 

I run my old 93 classic on fully snth 5w/40

 

Yep, if the engine is in good shape no reason not to use 5w-40.

If it is heavily modified or used hard on track then I would go thicker.

i have been recommended 15w-50 either motul 300v or mobil 1

 

Both very good quality oils.

si-thee, read the posts by JGM earlier on... I expect you'll be sticking in 15W-50 Motul 300V Competition afterwards!

EDIT: Oops, those posts were in another thread, lol. Basically, he clocked up massive milages on an engine (or two?) One engine was std initially, then seriously modded, and it saw a fair old mileage on the 300V Comp...

 

drained oil today then realised i forgot to buy a new filter tw@t!

 

Hoot!

Make sure you get a genuine Subaru filter (don't forget a new sump washer too .)

 

ive been using the k&n one seems to be quite good

 

Silkolene PRO R 15W-50 Ester Synthetic Oil For High Performance Engines at opie oils

looking at this one is it any good for my classic??

Its very good, but if the car is a daily driver you would be better off with the Silkolene Pro S 10w-50 as the 10w will flow better from cold then a 15w.
