Two oils here PYB and QSGB/QSAD, first off to my shock QS appears better on paper except for pour point. What say ye to the following and which would you choose?
PYB 5w30SN
PP -42C
CCS V 6100cp @ -30c
MRV V 25,400cp @ -35c
NOACK 14.9%
QSGB 5w30SN
PP -30
CCS V -6100cp @ -30C
MRV V 19,100 @ -35C
NOACK 14.3%
All these are from the Shell TDS. All methods of ASTM testing were the same. Is MRV the most important for the cold? Which would you choose and why? I may be a QS convert...but why the PP discrepancy?
Thanks
Matt
