Comparison Of Nissan Electric E-PSF and Ravenol E-PSF

[MolaKule]

Some time ago the question was asked about these new Electro-Hydraulic or ESPF fluids so here are two basic analysis of these fluids with average elemental analysis in ppm (any element less than < 2 ppm not reported):

Ravenol E-PSF, 1187002-001

Boron - 3
Silicon - 3
Sodium - 2
Calcium -12
Magnesium - 2
Phosphorus - 430
Zinc - 480
Kinetic Viscosity@100C - 6.2 cSt
Flashpoint - 365F

Nissan E-PSF, 999MP-EPSF00P

Boron - 105
Silicon - 13
Calcium - 3660
Magnesium - 15
Phosphorus - 2300
Zinc - 2500
Kinetic Viscosity@100C - 7.1 cSt
Flashpoint - 460F

Both fluids averaged out at a cost approaching $40.00/QT USD.

The message here for me is don't assume all ESP's are the same.

There is a huge difference in the add packages . It would seem I guess the Nissan has a higher flash point so potentially a higher quality base oil [blend?] which would be the better choice or is it application specific?

Nissan has a ton of zinc!!

While its flashpoint is lower its pourpoint and VI are exceptional at -75°C = -103°F and VI 312 respectively:

Visco at -40°C = -40°F is just 960 mm²/s.

Are these both same application?

I purposely omitted the base fluids and any specialty chemistry found for various reasons. I added the part numbers for each fluid.

Ravenol says it covers | NISSAN KLF51-00001 | NISSAN 999MP-EPSF00P | NISSAN E-PSF |??

The comparative chemistry is so different I would say these fluids ARE application specific, but would Ravenol really cover the Nissan fluids, I question that.
