Just ordered 7 quarts of redline high performance 5w-40 (NOT the Euro series) for my next oil change. Reason why I did not use local takumi was that they refused to provide MSDS sheet so I could not verify how much "hazardous" material is included in the oil which sorts of serves as basis to determine oil base. Since this oil is substantially thicker than group III oils, I will report on how it feels.
