From an old post:
This is a 2004 Lamborghini Murcielago, delivered Jan ‘04. It is reported to be delivered with Agip 5W-40 synthetic oil. About 2 months after delivery at 575 miles I changed the oil to 0W-30 Mobil 1. There was a valve click that disappeared and the whole engine got quiet after this first oil change. Unfortunately I tore the aluminum dry sump oil tank while trying to pry off the drain plug. It was repaired with adhesive.
In Dec ‘04 I had the dealership replace the oil tank and lines (a big job) while the car was also in for some other warrantee tweaks. The car mileage was 2,700 at that time. The oil was changed with the 0W-30 again. After driving 300 miles and again after adding 900 more miles I tested the oil (two left columns).
___Mobil 1 with 300 miles ___with 1,200 miles. This oil was dumped at 4,200 total car mi.
___The last column (right) is Red Line 5W-20, put in when the car had 4,200 mi. and at this analysis has 6,200 mi.
