had my wrx for 6 weeks, want to change the oil anyone got any ideas on what oil to use? 94 import 95000 k, cheers!

 

i got hold of silkolene pro s for my sti at £20 for 4L mate (0w-50) off ebay. checked and the retail is 37 squid so must be good stuff hurry though hope that helps

 

cheers mate, will have a look!

 

0-50w? I've alway been told not to use lower than 10-40w on a scoob as it's too thin???

 

I agree, 0W is way too thin!! especially on an 11 year old car!

5W is thin

10W is about right

15W is too thick and causes drag on the turbo and engine

IMHO of course!

0w-50 Pro-S doesn't exist!!!! LOL

I think you'll find Pro-s is 10w-50

So everybody stop the flipping "too thin" scare mongering and educate yourselves before making *****-nilly judgements based on hear say on a board full of "*****"

Actually, 0w-50...if you could actually buy any would be THICKER than a 10w-40 at normal operating temperatures or higher.


Please remember we are talking multigrade oils not monograde: The first 2 numbers are the COLD viscosity ratings (below zero degrees C) ...the last two numbers are the HOT viscosity rating.

http://www.millersoils.net/pdf_downl..._explained.pdf

 

Furthermore (as no doubt plenty of people can't be arsed to fire up acrobat reader )this is the specific limits set out by the SAE cold temperature "w" rating (the first one/two numbers in the viscosity rating of a multigarde oil)

SAE Viscosity Limits - cP @ Sub Zero Conditions
0W = 6200 @ -35°C
5W = 6600 @ -30°C
10W = 7000 @ -25°C
15W = 7000 @ -20°C
20W = 9500 @ -15°C
25W = 13000 @ -10°C


This is the actual viscosity limits set out by the SAE for the hot temperature rating of 100°C. (The last two numbers in a oil viscosity rating of a multigrade oil):

SAE rating = viscosity range @ 100 °C (Cst)
20 = 5.6 to 9.3 Cst
30 = 9.3 to 12.5 Cst
40 = 12.5 to 16.3 Cst
50 = 16.3 to 21.9 Cst
60 = 21.9 26.1 Cst

So a example, a 0w-50 verses a 10w-40:

0w-50 will be 6200cP at -35°C and 16.3 to 21.9Cst at 100°C
and
10w-40 will be 7000cP at -25°C and 12.5 to 16.3 Cst at 100°C

The higher the cP or Cst the thicker the oil, the lower, the thinner. So 0w-50 is THINNER than 10w-40w at -25°C But 0w-50 is THICKER than 10w-40 at 100°C

The same tables and rules apply to all mutigrade oils

 

My head's gone tight now.

 

STOP THE WORLD - I WANT TO GET OFF!!!!

 

PSL - you do get around don't you - get back to General ******** oil thread will ya

 

It's a hard fight .... the voice of reason in an **** ScoobyNet world!

Pete

 

shh Don't mention oil......

 

From the man who wants a new back box!!!
How many times have you have slagged off anyone who wants to change more than an air freshener on their scoob???
One third of your posts must have been about how good the impreza is standard, and why on earth would someone buy a car and then be dumb enough to modify it!!
You are a two faced, sad old man Pete.

Still wouldn't swap ya for the world though!

 

Aww come on, its easy to understand....and this is comming from someone who can't do integration or differentiation without the need for Mathlab to do it all for me

 

These days I don't ever feel the need to do that kind of thing. And I couldn't remember how to do it, anyway.

 

Take that bl@@dy sweatband off then.
So out now.
Even for you axemen.

 

You cannot be serious.

 

only wanted to know about oil, not maths?

 

my heads gone tight now!

 

If that's the bargain Silkolene 10w-50 PRO S on ebay, don't touch it!!!

If it's in metal 4 litres cans, it's at least 7 years old

Pro S actually comes in 5L cans, plastic.

You've been warned! Stock clearance I think not! I have to wait between 5 and 15 days for my fresh orders of PRO S to be bottled, there is no old stock other than on some Dealers shelf!

Cheers
Simon

 

have you not provided him with the oil change procedure?
