I never (ever!) used anything other than fully synthetics - Castrol TTS, Silkolene Pro2, or Rockoil Synthesis 2.
The Castrol smells the nicest, the Rockoil is cheapest... because of a very nice man at Rockoil South West!
If I ran out of oil, I'd never put anything else in until I found a supply of one of my three!
