Can anyone recommend a good oil now my DPF has been removed and the ECU remapped?

Can I use any 0w-30 or 5w-30?

The car has done 140,000 miles. Mazda 3 2.0D MZR Jan 2008

Thanks,

 

Still needs to be a diesel spec.
What oil were you using before?
In OZ we use Mazda DL1 oil.

 

I was using the Mazda original oil ultra DPF 5W30 made by Dexelia.

What I need to know is what is the best oil now? Do I need something like this?Mobil 1 ESP 5W30 5L
