An engine oil system and a lid

A lid, such as e.g. a filter lid, for closing an opening in an oil pan, said lid comprising:

• an expandable closing arrangement for closing the opening in said oil pan,
• a first elongated element having a first element connecting portion connected to first portion of said closing arrangement by a first pivotable connection,
• a second elongated element having a second element connecting portion connected to a second portion of said closing arrangement by a second pivotable connection distant from said first pivotable connection,
• wherein said first elongated element and said second elongated element are connected to each other by a pivotable jointer enabling said first elongated element and said second elongated element to be arranged:
• in a first relative position in which the first pivotable connection is separated from said second pivotable connection by a first distance which the expandable closing arrangement is in a first state in which the closing arrangement can pass through said opening, and
• in a second relative position in which the first pivotable connection is separated from said second pivotable connection by a second distance being greater than said first distance in which the expandable closing arrangement is in a second state, or an expanded state, in which the closing arrangement cannot pass through said opening.
