Schönen Tag an Alle,

after two years, only reading this nice forum, maybe I can help you. I have had the same problem with my Urraco 2.5 when I was changing oil and filter. 20w50 is the recommended oil by Lamborghini, and for this car the best, so I found an Austrian company (www.classol.com).
The oil is perfect, cheap……………
You can use two types of filter, I will tell you tomorrow.

Liebe Grüsse
