Red Band engine oil
Roger Roger, as far as I am aware Aeroshell 100, Mobil Red Band and BP Aviation Oil 100 are all 'non-compound' (no additives) mineral oils suitable for use during the initial period of engine life. Different manufacturers specify different hours of operation during which Red Band, or an equivalent, should be used. Other posters to this thread have suggested that some even suggest it be used throughout the life of the engine. Mobil is the only provider which calls their product Red Band as far as I am aware. You may care to look at the Esso link provided by Matt_Hooks in one of his posts. My only other suggestion is that, if you are really wanting to know the "good oil" on this matter you could call Mobil, Aeroshell or Air BP technical advice lines.
