The Grade 0 of MOV Long Life is about 80% so a bit of oil separation is not a problem. You would need to lose an awful lot to change the grade. For MOV's most use a Grade 3 as the maximum in-service limit. The free oil can normally be mixed back in or decanted. If an issue consider using the Grade 1 which has less oil separation. The alternative is the age hardening problems of the previous calcium complex grease and lack of lubrication. The previous grease was considered 'marginal' in some of the EPRI testing. Plus in oxidation testing MOV Long Life is outstanding. Some stations are approaching 4 times the service life in high ambients.
