Reply to "Advice on Oil Viscosity for a fast road/race engine"

Anthony,

Just means you can start car in Artic and the oil flows very quickly when cold. Synthetics have naturally low W numbers. Full on race cars can use 0W20 oils for extra bhp. Scooby rally cars use Motul 300V 5W40 which may suit your use but a bit pricy.
