HTHS Castrol TWS 5.4
HTHS Redline 10W-60 6.7(25% higher)
Once you shear past film strength the last line of defense before metal to metal contact is Zinc and Phosphorus.
ZDDP Redline Z&P= >1200PPM
ZDDP TWS Z&P 800/650PPM
It really boils down to these numbers and not how you "FEEL" about a particular oil or brand. Show me another 10W-60 oil with better numbers than this and I will use it!
