- Applications
- Application Instructions
To apply the grease:
- Wear protective gloves.
- Clean and dry the surface being lubricated with a lint-free cloth or brush and a zero-residue cleaning solvent, such as MG 824 Isopropyl Alcohol.
- Apply a thin, even layer of grease using a spatula or other appropriate applicator.
Attention!
Carbon grease is messy and transfers easily. Be careful not to spread it beyond the intended area.- Application

- Physical and Synthetic Oil Properties Note
- Values based on synthetic oil component only.
- a) High oil viscosity index of more than 100 indicates a small oil viscosity change with temperature.
- b) Temperature at which oil will continue to burn for at least 5 s after ignition with an open flame.
- c) Cleveland open cup method.
- Emcor Rust Test, Distilled Water Note
- a) Corroded areas covering >1% but <5% of the running track surface.
