LP640 - Does it really eat that much oil?

I've found it sometimes hard to get an accurate read and the best thing to do is follow the manual exactly. I always check when oil is hot after a drive making sure car is level. If it says to check with engine off see if they tell you how long to wait before checking and follow that. I'd also speak to your service dept. as they may have learned the best practical way to check the oil level. I've also found that modern cars seem to burn very little oil.

The Murcielago should be checked with the oil HOT and within 5 minutes of shutting down the engine. It is a dry sump system.

My manual says to check the oil while the car is running

 

Better double check that, I think it should be off and is recommended to not be checked while running even though you are checking it on the low pressure side of the sump.

 

If the LP640 is anything like the Gallardo then consumption of oil is normal; the G manual says it can eat up a liter of oil for every 1000 kilometers as part of normal operations. I found I was well below the low mark after two track days in a weekend, stupid me for not checking it after the first day, but fortunately the car holds nearly 10 liters so a little low is not the end of the world. Regardless, the testing procedure is get the car up to operating temperature, rev to ~2000 rpm for 50 seconds, idle for 5, turn off and check within 60 seconds or your reading will be useless. I've got a very detailed howto on Gallardo oil check and top off at http://www.*********.com/showthread.php?t=13 Much of the info probably carries similarities to the LP640.

 

I checked the manual again. It says check the oil while it is idling

 

That's odd that it would be opposite the G and Murci.

 

Does the car have a low oil warning light ? ...just in case...

 

In the G there isn't one, just a low pressure light, and you have to be very low on oil before you're that low on pressure.
