hey all looking for recommendations between these two oils. Pennzoil ultra platinum 5w30 is on sale on amazon now for $27 ish and I can get Castrol Edge 5W30 at walmart for the same price so looking to compare which is the better buy
Castrol Edge 5w30 has the following
Density @ 15C: 0.85
Viscosity, Kinematic 100C : 10
Viscosity, Kinematic 40C : 57
Viscosity Index :164
Pour Point : -39
Flash Point : 225
Ash, Sulphated ASTM D874 % wt 0.78
while PUP 5w30 has the following:
Density kg/m3 : 841
Kinematic Viscosity 40°C : 56.3
Kinematic Viscosity @100°C :10.3
Flash Point °C : 203
Pour Point °C : -48
Viscosity Index ASTM D2270 173
Edge has the higher flash point at 225 but a lower pour point at only -39
VI is also lower in 164
I watched the youtube video and PUP 5w30 apparently has a borate ester.
I know there is more to these oils compared to just the specs. Also I am not the best in comparing VI and pour point and flash etc
however which is the 'better' buy? OCI doesn't matter since I change it early anyways just looking for the most stouty oil
thanks
