I have used Amsoil since 1994 in all my engines and like their oils. I am thinking about switching my bike (Suzuki gsxr1100) to Maxium Extra 4 oil since there ZDDP and CA are WAY higher. Plus the price for the Maxium, it is cheaper then Amsoils oil even at dealer price.
I believe Amsoil is a group 4 (PAO) and Maxima is a group5 (ester-based)
Here is what I found for oil tests:
Amsoil’s new stuff;
20w-50 Motorcycle bike oil (NEW): HTHS =6.02
TBN=11.0
VI=153
Noack Volatility=3.89%
Kinematic Viscosity @ 100°C=20.1 cSt
Kinematic Viscosity @ 40°C=151 cSt
CCS=5609
Pour point=-38 F
Flash Point=464 F
ZDDP 1031 & 946
Ca 3852
Maxima Extra 4 15w-50
TBN 12 (new)
Phos 3300+ppm (based on used with 2400+ miles)
zinc 2400+ppm (based on used with 2400+ miles)
HTHS: 5.5 (new)
VI 164 (new)
KV @ 100: 17.42 (new)
KV @ 40: 116.8 (new)
Any thoughts? Good, bad???
