Engine Oil
In the Bristol 407 handbook, it advises using, as engine oil, Mobiloil Special 10/30 or Esso 20/30 or Energol SAE 30.
This is odd as most V8s of this period are recommended to take a 20/50.
What is the best oil to use? A single grade sae 30 or a 20/30, as apparently recommended by Bristol, or the widely used 20/50.
In a similar engine Jensen recommend a 20/50, so why are Bristol, for a near identical engine, recommending only a 20/30? Does anyone know?
