What conclusion can I derive from the grade of the oil? I assume one is lesser quality. How would I know which oil is right for my system? Been using Eastern for awhile and this is a new issue. Could be that my tank got contaminated with water or something.

Water in the tank is more likely than shoddy oil imo. You want grade 2 for residential. Grade 1 is cheaper but burns less efficiently and makes more waste.
