A mobile prepressurized fluid storage tank is disclosed where the compressed air, completely separated from the fluid by a flexible diaphragm, dispenses the fluid under pressure, e.g., into an engine. The prepressurized diaphragm-type fluid storage tank is initially charged with a gas on one side of the diaphragm. A connector on the other end of the tank is connected to the fluid pumping system. Fluid is pumped into the tank until a predetermined pressure is reached and then the fill valve is shut off. A second connection attached to a bottom system connection has a hose. At the end of the hose there is a fluid shut off valve. Dispensing of the fluid takes place through the fluid shut off valve. The prepressurized fluid storage tank is mounted on a frame that contains wheels for mobility.

What is claimed is: 1. A method for dispensing oil or other fluids at a site where the oil or other fluid is required for maintenance of mechanical equipment, the method comprising: providing a mobile prepressurized diaphragm/bladder type storage tank, wherein the tank comprises a first chamber for storing a fluid to be dispensed and a second chamber for storing a gas under pressure, a flexible diaphragm/bladder attached to the tank, a pressurizing port for supplying a gas to pressurize the second chamber and a port in the first chamber for filling the chamber and/or for supplying the oil or other fluids under pressure, said mobile prepressurized diaphragm/bladder type storage tank being structured and arranged mobility for ease of access to any location; pressurizing the second chamber with the gas, wherein the gas is located on one side of the diaphragm/bladder; filling the oil or other fluid into the first chamber, wherein the oil or other fluid is on the opposite side of the diaphragm/bladder; moving the mobile prepressurized diaphragm/bladder type storage tank to the site where the oil or other fluid is needed for maintenance of mechanical equipment; and dispensing the oil or other fluid under pressure. 2. The method according to claim 1, wherein the diaphragm/bladder is attached to the tank using a ring that exerts pressure against the diaphragm/bladder to fix it inside the tank. 3. The method according to claim 1, wherein the first chamber is a lower chamber and the second chamber is an upper chamber. 4. The method according to claim 1, wherein the pressurizing step chronologically precedes the filling step. 5. The method according to claim 1, wherein the filling step precedes the pressurizing step. 6. The method according to claim 1, wherein oil is dispensed into an engine. 7. The method according to claim 1, wherein during the pressurizing step, gas is provided into the second chamber until a first pressure is attained within the second chamber and, then, a fluid is filled into the first chamber until a second pressure is attained, whereby the tank is ready for dispensing the fluid under pressure. 8. A mobile prepressurized diaphragm/bladder type storage tank capable of being moved to a site where the oil or other fluid is needed for maintenance of mechanical equipment, the mobile prepressurized diaphragm/bladder type storage tank comprising a first chamber for storing a fluid to be dispensed and a second chamber for storing a gas under pressure, a flexible diaphragm/bladder attached to the tank for separating the gas from oil or other fluids to be dispensed, a pressurizing port for supplying the gas to pressurize the second chamber and a port in the first chamber for filling the chamber and/or for supplying the oil or other fluids under pressure for maintenance of mechanical equipment, said mobile prepressurized diaphragm/bladder type storage tank being structured and arranged mobility for ease of access to any location. 9. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein the second chamber limits the displacement of the flexible diaphragm/bladder when filling the first chamber. 10. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein the diaphragm/bladder is attached to the tank using a ring that exerts pressure against the diaphragm/bladder to fix it inside the tank. 11. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein the first chamber is a lower chamber and the second chamber is an upper chamber. 12. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein oil is stored in the first chamber. 13. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein the second chamber has a stem valve for introducing a pressurizing gas. 14. The mobile prepressurized diaphragm/bladder type storage tank according to claim 8, wherein the second chamber contains a pressurizing gas. 15. A mobile prepressurized diaphragm/bladder type storage tank comprising a bottom chamber for receiving a fluid to be dispensed and a plurality of domed chambers for receiving a pressurized gas, a flexible diaphragm/bladder attached to the tank for separating the gas from the fluid to be dispensed, a pressurizing port for supplying the gas to pressurize the domed chambers and a fluid port in the bottom chamber for filling the tank with fluid to be dispensed and/or dispensing the fluid under pressure, wherein a first domed chamber has an opening in the dome for communication of pressurizing gas with a second domed chamber, and wherein the pressurizing port is in one of the plurality of domed chambers. 16. The mobile prepressurized diaphragm/bladder type storage tank according to claim 15, further comprising a diaphragm retainer located in the fluid port. 17. A method for reducing the absorbsion of water into the oil when stored and dispensing oil into engines at a site where the oil or other fluid is required for maintenance of such engines, the method comprising: providing a mobile prepressurized diaphragm/bladder type storage tank, wherein the tank comprises a first chamber for storing a fluid to be dispensed and a second chamber for storing a gas under pressure, a flexible diaphragm/bladder attached to the tank, a pressurizing port for supplying a gas to pressurize the second chamber and a port in the first chamber filling the chamber and/or for supplying the oil or other fluids under pressure, said mobile prepressurized diaphragm/bladder type storage tank being structured and arranged mobility for ease of access to any location; pressurizing the second chamber with the gas, wherein the gas is located on one side of the diaphragm/bladder; filling the oil or other fluid into the first chamber, wherein the oil or other fluid is on the opposite side of the diaphragm/bladder; moving the mobile prepressurized diaphragm/bladder type storage tank to the site where the oil or other fluid is needed for maintenance of mechanical equipment; and dispensing the oil or other fluid under pressure, thereby reducing the addition of water into the oil to reduce engine wear due to corrosion.
