The comment "EP oil eats bronze" could you explain a little more? First what does the term EP stand for? Is this a brand issue only in New Zealand and Australia? My reason for asking is of course there are lots of bronze bushings etc. in CMPs and this is first I had heard of one of the gear oils being non-compatible.
