Focus oil change system

Abstract

Used motor oil and other used engine fluids can contain toxics such as benzene, lead, zinc, and cadmium. One quart of waste oil can ruin the taste of 250,000 gallons of drinking water and one pint can produce a slick covering one acre. Oil dumped on the land reduces productivity and 50 ppm can foul sewage treatment processes. Crankcase oil accounts for 40 percent of total oil pollution in our waterways. Today many automobile owners have their oil changed and disposed of by a professional, but there are thousands of Do-It-Yourselfers changing oil and other fluids in automobiles, outboard engines, lawn equipment and other power equipment. Unfortunately, since there has not been an easy way to change and dispose of these fluids, it has been either dumped on the ground or into a sewer. The FOCUS System provides an easy way to collect these fluids in a flexible, disposable, plastic bag, which is sealed and may be disposed at an EPA approved site.

1 . I claim a one time use, Disposable Fluid Change System, which may be composed of several different transfer systems to drain or pump used oil or other used fluids directly into a flexible, disposable, plastic bag, where it is easily sealed and may be disposed in an environmentally friendly manner. 
 One unit is a hand-operated vacuum pump used to pump used fluids, motor oil or other fluids, from the engine, via the fill or dipstick aperture, with a direct connection to a disposable plastic bag.    The second system utilizes a rubber drain boot, which is slipped over the fluid fill inlet and directly connects to a disposable plastic bag with a flexible tube. The engine is tipped and the fluid drains by gravity into the bag.    The third system consists of a flexible disposable bag with a capped opening, sometimes utilizing a catch bowl, where the oil is drained by gravity directly into the disposable plastic bag.    The unique feature of this system is the placing of the oil directly into a flexible, disposable plastic bag.
