Changing Oil On C5 Diesel 2.0hdi 2004 Model

[Maddersc5]

Does the under tray have to be removed to get at the oil drain plug please ?

 

What quality engine oil should i use ? Thanks

Yes! the undertray has to come off and it's easier if you get the car on ramps with the suspension raised. 5W40 oil to API CF. Change the filter at the same time.
