Motul chrono 10/40 would be a good choice.

 

You also need to take into account your oil temps as this really determines what oil to run. If your running over 500 bhp then look at 15/50 etc

 

Competition Engine Oils
All Millers Oils Motorsport full synthetic formulations combine 3 synthetic esters with high performance additives and friction modifiers to provide maximum power output with minimum wear. The high ester content reduces the amount of polymer in the formulation and increases the oil’s resistance to shear and loss of viscosity.

CRO 10w40 Data sheet 1101
Competition running in oil. A race engine must not be run in on a semi or full synthetic race oil. Ideal for test bed running.
CFS 5w40 Data sheet 1102
Full synthetic “3 ester” formulation.
Suitable for fast road, race, rally, sprints and hill climbs. Ideal for engines with hydraulic tappets e.g. Ford Zetec.
CFS 10w40 Data sheet 1103
Full synthetic “3 ester” formulation.
Suitable for smaller capacity race and rally engines and turbocharged engines for fast road and track days. A performance alternative where the manufacturer specifies a 5w40.
CFS 10w60 Data sheet 1104
Full synthetic “3 ester” formulation.
For larger race and rally engines, with and without turbochargers. A performance alternative where the manufacturer specifies a 10w40.
CFS 15w60 Data sheet 1111
Full synthetic “3 ester” formulation.
A slightly heavier base viscosity to give maximum protection in high ambient temperatures and highly stressed applications. Ideal for turbocharged engines and endurance racing and rallying.
