Is it still possible to get Castrol RS 10w60 as all local car accessory shops only stock Castrol Formula RS 0W-40 which I assume is not really suitable for the WRX. The Castrol web site has no contact numbers or e-mail address so that proved a fruitless exercise. If I have to mail order the oil I will as the cars always had RS and I would like to keep it that way.
Cheers for any help,
Jas.

 

Well my local garage has just (yesterday) serviced my car and the only fully synthetic of at least 10-50 they could get me was Castrol RS 10-60 which took them some time to find.

Don't know if this is any help to you but I am sure it has not been discontinued.
