Great for Spec Miata race car.
Lower viscosity than most 10-30 oils but higher anti wear additive package.

This is the stuff!
The only oil I will feed my Spec Miata. Oil analysis showed good activity after four race weekends, but I change after every other one.

No markings
The bottle has no markings for quarts or liters left inside. It was a pain trying to figure out when I was near 3.7 quarts. Have gone out since and bought measuring cups in a paint department to assist in future
