Re: Where to buy Castrol TWS 10W-60? Ridiculous M5 oil consumption...
Did you check the oil level on the same level service and the same engine temperature. The level will be lower when cold
That sounds heaps of consumption, my car doesn't use any noticable amounts between oil changes - 6,000 miles
TWS is different to Castrol RS (A castrol 10/60 available from most outlets) It's BMW or Ascari or companys like Bavarian Automotive I'm afraid.....
