System for facilitating an oil change and/or an oil filter change in internal combustion engines

A system for expediting a change of motor oil in internal combustion engines which include a crankcase, said system comprising:

• extraction means for extracting oil frown the crankcase;
• filling means for filling oil into the crankcase;
• control means for controlling the operations of extraction and filling of oil;
• the extraction means and filling means including:
• first duct means which have a first end fixed in the proximity of the lowest point at a bottom portion of the crankcase, said first duct means having a second end which has a first connecting means;
• a second remote duct means releasably connectable by a second connecting means to said first connecting means of said first duct means;
• a remote unit for extraction and filling of oil, said remote unit being connected to said second duct means;
• wherein the control means includes means for carrying out a controlled suction of oil from the crankcase, through said first duct means and said second duct means to said remote unit, and means for carrying out a controlled filling of the crankcase supplying oil from the remote unit through said second duct means and said first duct means;
• the remote unit being connected to at least a first tank for storing oil extracted from the crankcase, the remote unit being connected to at least a second tank from which oil is supplied to the crankcase, the remote unit includes means for controlling the quantities of oil extracted from and supplied to the crankcase respectively, and
• the remote unit includes means for processing and storing data relating to the quantity of oil extracted from and supplied to the crankcase, respectively;
• and
• the first duct means comprises one single duct through which oil is pumped during extraction from the crankcase as well as during filling of the crankcase.
