Hi guys, the top bolt which releases the oil filter housing appears to have rounded slightly and the 32mm socket is now slipping! Any ideas how I can get this off? 

 

The car is now almost at 160k so this will be the final oil change before it gets shifted on 

 

Any help or advice would be much appreciated

 

Thanks 

 

 

If your using a multipoint socket try a 6 point as it should not slip and round of the edges.
