Abstract: A cart is provided for delivering fluid to vehicles including aircraft. The fluid can be, e.g., engine oil or hydraulic fluid. The cart has a tank, mounted to a carriage mounted in turn to carrying wheels. The cart has as a dispensing means, a hose ending in a nozzle. Fluid, e.g. oil is added to the tank, followed by an inert gas, e.g., N.sub.2, which pressurizes the tank to about 120 psi. The cart is wheeled to an aircraft and oil delivered to its engines through the dispense means. Such delivery system replaces delivery by quart cans or by mechanical pumps, which have had inefficiency, waste and contaminant drawbacks.
