For those DIY'ers out there like myself, I am putting together a walk-through tutorial of doing an oil change on a Murcielago. It's not altogether different from doing an oil change on any other car, but because of the dry sump system there are some caveats to the norm. I will be adding pics and updating based on feedback I receive. In the meantime, I will post what I have.
Please refer to the following images the service manual when reading the content below.
I am using Esco jackstands and they work great for the Murci!
Just take care of your nose-to-ground clearance when lifting from the rear!
I use measured propylene pitchers to catch the drain oil so I can accurately measure how much oil comes out. Click here to buy.
For routine oil changes on the Murcielago I have been told by an expert at LamboStuff that one should NOT drain the oil tank (drain plug marked as "1" in the above diagram), but instead should only to drain the sump (two drain plugs marked as "2" in the diagram above), in order to avoid letting the crank go completely dry. Additionally I was told that the oil tank drain plug is very fragile and the spout can bend if too much torque is applied. Note: This tutorial is mostly based on feedback from Logan @ Lambostuff, but also includes recommendations and tips from multiple forums, as well as the bit of information that is available in the service manual. Caution: You will be working with a hot engine and hot fluids for most of these steps! Wear gloves, eye protection, and take care to avoid burns! Recommended Materials:

- 8mm Hex socket
- Torque wrench
- Oil filter wrench Instructions
1. Warm the engine to operating temp (> 70C) then turn off the engine.
2. Uncap the oil tank cap in the engine bay (A). This allows oil to flow out of the tank and into the sump in the following steps.
3. Remove one of the two drain plugs on the sump using an 8mm hex socket bit (2).
4. Wait for a slow drip (ie. don't let it drip for a long time like one might do on a non-dry sump system). Depending on several conditions the oil flow may start out being high and then slow down rapidly after the first 3-4L come out. The oil drain may become a very slow, thin drain. That is normal.
**If possible, take note of how much oil came out. This is the amount you should put back in (ie. don't overfill!).
Take care not to "over drain". You will likely be leaving 2-3L in the car after you finish draining. This is as far as you should go for a DIY oil change on the Murcielago. Attempting a more thorough drain risks running the crank dry which could result in an engine rebuild down the road. You have been warned! If a complete drain is required then it might be better to take the car to a professional.
5. Replace drain plug on the sump (2) and use a new crush washer. Use a torque wrench to tighten the drain plug to about 20-22 ft-lbs.
6. Remove old oil filter.
7. Fill new oil filter with oil and lubricate the filter gasket with oil.
8. Reinstall the new filter, hand tighten.
9. Fill the engine (B) with 3L.
10. Fill the oil tank (A) with the amount of oil needed to match the volume that drained minus the 3L put into the engine. 8L max.
11. Take care not to overfill!
12. Warm the engine to operating temp.
13. Turn off the motor, let it sit for 30 seconds. Check for leaks.
14. Check fluid levels, ensure level is between min and max dots. If oil must be added, repeat steps 12-14. Notes:
-Either drain plug on the sump will work. If using a lift then use the one that is closest to the back of the car. If using a floor-jack to lift from the rear then use the drain plug that is closest to the front of the car.
-Tightening the oil filter with the "One-and-a-half turn after it starts to tighten" method works fine for the Murci.
Here is a neat little 3/4" PVC setup I found while surfing that can facilitate getting oil into the oil tank filler (A).
