"Im thinking of moving away from mineral oil. Currently running Penzoil 15W-40. Do they mix? Is it a straight change with filter,or do you have to remove every drop of mineral oil first. Are blends OK for interim period? Engine only 55 hours since last rebuild, its still pretty clean inside. Guy recommended a brand to me a few weeks back, not sure I can get it in oz."
