Oil Change 2004 Audi a4 1.8TQ
 

I usually use Lubromoly 5w30 with Mann filter from my supplier but they are no longer able to supply me with 5w30, but they can get the 5w40 and Mann filter instead. I found another place that has the 5w30 but can only supply me with a Purolator brand filter. My question is should I go with the 5w40 and Mann or 5w30 and Purolator?


Would it make any difference to me?
