The 85W140-MIN BIG TWIN is a high performance mineral-based transmission oil formulated with premium quality paraffinic base oils and advanced additive technology.
The 85W140-MIN BIG TWIN offers the combined benefits of our ANTI-FRICTION TREATMENT and our ACP Polymeric Technology. The ANTI-FRICTION TREATMENT creates a lubricating film that prevents the metal-to-metal contact and the ACP adhesive / cohesive polymer, prevents wear that occurs during dry starts by gripping to gears.
The 85W140-MIN BIG TWIN:
- Is recommended for 4, 5 and 6 speed Big Twin transmissions
- Reduces the “clunk” noise when shifting
- Prevents wear caused by dry starts by gripping to gears
- Provides smoother shifts
- Helps reduce gear whining
- Helps detect oil leaks due to its red colour
- Is designed to lubricate differentials and shaft drive transmissions as well
The 85W140-MIN BIG TWIN meets and exceeds the API GL-5 standard.
