Garry - as a follow up.

You will be pleased to know S-TEC have confirmed that OIL0002 (TF-753) has now been replaced by OIL0005 (TF-870).

So they have indeed rationalised to just the one oil type. Like Ravenol, it would still be a lower viscosity than the original oil, but otherwise could be considered suitable where TF-0753 is specified.



Good to have confirmation from S-TEC.

By comparison the viscosity of Shell TF-0870 is:

28 mm2/s at 40degC
6 mm2/s at 100degC

Interestingly, the viscosity of ZF Lifeguard 6 is:

26.8 mm2/s at 40degC
5.6 mm2/s at 100degC

All three oils list identical hazardous chemical ingredients. The only difference between the 3 is the viscosity, the ratio of the hazadous additives, and the inclusion of any non-hazardous additives not listed on the MSDS.

Looking into different oils for transfer oil and found the Penrite DCTF004 has literally the same viscosity as TF-0753

Volume: 4L
Colour: Clear Natural
Density at 15°C, kg/L: 0.851
Viscosity, Kinematic, cSt at 40°C: 32.0
Viscosity, Kinematic, cSt at 100°C: 6.8
Viscosity Index: 177
Viscosity, Brookfield, cSt @ -40°: 11,600
Phosphorus, Mass %: 0.016

Also Castrol Transmax Manual FE 75W
Is very similar

Density @ 15C DIN EN ISO 12185 g/ml 0.852
Viscosity, Kinematic 100C ASTM D445 mm²/s 6.3
Viscosity, Kinematic 40C ASTM D445 mm²/s 32.2
Viscosity Index ISO 2909 None 154
Viscosity, Brookfield @ -40C (75W) DIN 51398 mPa.s (cP) 10000

This is an old thread I know but just curious on your thoughts would it just be the additives arnt suitable 🤔
