## Questions & Answers

**Q: Is it gear box oil**
A: I used it in the Differential on my classic car (Austin Healey Sprite). The gearbox on my car used 20 50 oil. Suggest you check online to see what your gearbox needs.

**Q: Hi which oil is most like castrol d40?**
A: Hi, do you mean D140? This is a bit thinner than that.

**Q: The objective i am seeking  is to keep my blade lubricated  on a Khukuri so no air or moist can come in direct contact of the blade**
A: Hi, probably better off with a product like the ACF 50 or Bilt Hamber Dynax UC.

**Q: Can you use this in the differential?**
A: Castrol EP90 is a high pressure oil rated to GL-4 standard making it suitable for use in standard/low power axles and differentials. However, high performance and limited slip differentials require a GL-5 rated oil. For axles the GL and the viscosity ratings are important, I would check what is recommended for your diff.
Hope this helps
