Default RE: After Run Oil And Omega Fuel ( Morgan )

nitro will attack the chrome on the bearings first as they are plated chrome and nitro is hygroscopic which means it attracts water big time,
Beware! I am going on just my memory here. But!?
Nitro does not attack chrome and is not very hygroscopic. Nitro will only absorb about 2% of its weight in water. Its the alcohol that absorbs water. You may be confused because drag racers used to clean their nitro fuel tanks with a mild acid like vinegar. This was to neutralize any alkalies in the tank, alkalies can react with nitro to form a contact sensitive mixture. By contact sensitive I mean the whole tank of fuel could go Kaboom during a crash. Also rust can react with a fuel additive propylene oxide which makes it contact sensitive to shock and static. The mild acid will also help remove any minute iron oxide which may be present but not visible.
