Supercharger oil breaks down over time from heat, moisture, and shear forces. Low or contaminated oil can lead to bearing wear and snout seal leaks — both common issues on Jaguar’s Eaton-equipped supercharged engines.

This tag covers supercharger oil refill kits for Jaguar models using Eaton M90, M112, M122, and TVS units. Each kit includes the correct specification synthetic oil, a syringe or dispenser for accurate fill, and clear refill guidance.

Replacing the oil at the right intervals keeps the supercharger lubricated, quiet, and reliable — avoiding the whine and drag that come with old fluid. All Powerhouse kits use oil matched to Eaton’s own standards and are used by professional rebuilders worldwide.
