If you check the product spec sheet though, the viscocity is different so im worried this aint the same oil and reluctant to be the guinea pig especially when these boxes are known to be picky !

Now im no expert, but these numbers aint the same folks!
Mobil 428: Density @ 15 C, g/ml, ASTM D4052 = 0.866
Mobil 424: Density @ 15 C, kg/l, ASTM D4052 = 0.880
Mobil 428: Kinematic Viscosity @ 40 C, mm2/s, ASTM D445 - 59
Mobil 424: Kinematic Viscosity @ 40 C, mm2/s, ASTM D445 - 55
Mobil 428: Viscosity Index, ASTM D2270 = 141
Mobil 424: Viscosity Index, ASTM D2270 = 145
Mobil 428: Flash Point, Cleveland Open Cup, °C, ASTM D92 = 243
Mobil 424: Flash Point, Cleveland Open Cup, °C, ASTM D92 = 198
Mobil 428: Pour Point, °C, ASTM D97 = -48
Mobil 424: Pour Point, °C, ASTM D97 = -42
Maybe we have an oil / hydraulic fluid expert in here though... |
Hi.
Are Petronas products available to you lads? I am guessing they are.
They offer a product for our NV245 transfer case.It is called Petronas Tutela Powergear4. It lists MS-10216.
It is what the UK Jeep dealers were selling. I have it in my 2008 transfer case and it works just fine. It is after all 'just' a Tractor fluid.
Here is the technical data sheet for comparison.
