I did find Motul 300V 15W/50 full synthetic. Maybe this one?
Designed for racing and vintage cars - see below:
Motul is a Performance formulated oil and and has extremely efficient anti friction properties.
300V's are 100% SYNTHETIC and include none-or very little (*)-viscosity boosters to achieve an extraordinary high resistance to shear stresses.
The common characteristics along the whole 300V line are :
- a remarkable decrease of the engines internal friction, which guarantees high performance and reliability, quite often topped with a noticeable decrease of running noise.
- an excellent resistance to high temperature charring - an extreme resistance of the oil film - a low volatility, with very little evaporation at high temperatures.
100% Synthetic – Double Ester Technology

Because you can increase the length of time between service intervals with total confidence, it can actually work out to the same cost as cheaper lower quality brands.
