EMERGENCY services are on scene of a Maiden Gully oil spill measuring about a kilometre on Olympic Parade.
A Country Fire Authority spokesman said it appeared oil had leaked from a trailer that had come from the tip.
He said police were trying to find the car responsible for the large spill.
The incident occurred about 1.05pm on Thursday. The Country Fire Authority and Bendigo council are on scene.
A CFA spokesperson said a number oil spills on High Street, Kangaroo Flat, appeared to be linked to the incident in Maiden Gully.
Emergency services were called to spill at the intersection of High Street and Lockwood Road about 1.40pm.
The spill was contained about 1.55pm.
Emergency services have also been called to other spills on High Street near Lansell Square and the Crusoe Road intersection.
One outbound lane on High Street has been blocked as a result of the spill. No intersections have been closed.
A VicRoads spokesperson said they will be looking into a number of spills on High Street, Kangaroo Flat.
"It's disappointing that people are not checking their load and making sure it's secure," firefighter George Pantazis said.
"As you're aware, oil can be a hazard and now this is tying up emergency services."
It follows an incident in Eaglehawk on Thursday morning where 200 metres of oil covered the Upper California Gully Road.
