I am seriously considering changing the engine oil brand from Mobil 1 ESP 5w -30 to Shell Helix Ultra Extra 5w-30.

The reason is that the Mobil depot & Mobil Australian distributor do not offer service , it is not available at times & the 20 litre drums sealed tops leak & they arrive in a very dirty & dusty condition.

The Shell is cheaper & the seller keen to do business.

My question is , are the products equal in quality as far as my 220 CDI diesel ?. Are there any preferences ?.Which would be the most suitable to lengthen service life?

Both oils are MB 229.51.

Below are the specs :-
