Well me my95 wrx is at 57 k and thinking of doing an oil change ,not sure which grade and make of oil to use and how much she`ll take , i think its been run on mobil one ,but not sure of viscosity,when i do the change do i need to get a new sump bolt and washer , is it a supplier job ?
it maybe a daft question, but dont want to risk me pride and joy going bang , thanx

 

You should find all you need to know using the search function.

Castrol RS 10 60 is great stuff and you'll need 4.5 litres of it.

 

Yep, Castrol RS seems to be the preferred one.
I'll be using that next.

I think you can buy it from Castrol Direct..although cant find the number at the moment.

 

would it be ok to use castrol even though its been run on mobil one , isnt that castrol rs the stuff hasell ,alot cheaper than mobil isnt it ?

 

I would rekon it should be fine, think it would only cause a problem if you started mixing them.

 

I saw some Castrol RS 0-50 at Halfords, didn't see any 10-60, what's the difference?
