An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.

An overbased calcium magnesium sulfonate grease composition and method of manufacture comprising both overbased calcium sulfonate and overbased magnesium sulfonate in a ratio range of 60:40 to 100:1. The grease is made according to any known method for making an overbased calcium sulfonate grease by using the overbased magnesium sulfonate in addition to the overbased calcium sulfonate. A portion of the magnesium sulfonate may be added prior to conversion and another portion after conversion, with or without one or more delay periods between the addition of water or other reactive ingredient and the addition of magnesium sulfonate. The grease can be made using calcium hydroxyapatite and/or added calcium carbonate as calcium containing bases for reacting with complexing acids, a non-aqueous converting agent delay method, added alkali metal hydroxide, or any combination thereof. The grease has a high dropping point and reduced thickener yield.
