Note viscosity is slightly lower than normal limits.

Particle count indicates that oil cleanliness level is near to unacceptable range.

Varnish & Sludge Potential Index (VsPI) indicates a minor amount of varnish & sludge products are present in the oil.

Suggest using an off-line filtration system to clean up the oil system.
