Lamborghini Murcielago Oil Change

There's a far distance between 12-18K miles on an engine vs. 4200-6200 w.r.t break-in wouldn't you say ? And, if you read my posts, you'd know that there is much more than Fe wear reduction going on with my engine.

I would be quite interested in why fuel dilution took such a sharp change in the 3rd oil sample of Dr Haas' engine. Either something changed drastically, there was a lab error, or RedLine has some killer ring sealing properties.

I doubt that the Doc would waste time showing off on an internet board where no one can see anything. In addition, I don't see why anybody should be ashamed of having money or being successful. This is an oil board, if we don't care what oil he uses in his nice car, why should anybody care what anybody else uses in lower cost and less exotic cars?

I don't know if you are jealous or not but what a lousy thing to say. You were perfectly free to not post anything in this particular forum.

The truth is that we are lucky he has no reservations in posting here in in an upfront manner. We would all benefit greatly if more people with exotic cars would post here.

Judging from the Docs reply to you it is obvious that your malice does not affect/effect him much, but it might deter others. This thread is important to me, and your negative paradigm is not reality for everybody. You are perfectly free to peruse the threads you wish, and avoid the ones that you do not enjoy. It really is quite simple isn't it?
Thank #@$%!.

I thought about this. I would say more akin to benchracing.I would say Dr. is enjoying himself . I enjoy his posting

Dr. AEHaas maybe you should start a thread for the young kids here to tell them what you had to go through in life to get to be so successful to be able to purchase a ride like this. Your car is definitely a quantifiable measurement of your success, all hands down.

When the day comes when my biggest worry will be what kind of an oil I should use in my Lamborghini, I will be one happy man. Unfortunately there are a few loser on this board that instead of being creative or ambitious, are just jealous of other peoples’ success.

Actually my wife will notice things as engine sounds or tire pressures even before I would. She is very particular. Although she may not be able to get the car up on the lift exactly right she can certainly change the oil by herself. She is a do-it-yourselfer in many ways.

One of my concerns is that she will notice something if I change to Motorcraft.

Dr Hass,

I do not care what this other guy wrote, I am certainly willing to give you the benefit of the doubt based on what I perceive is your passion for oil.

I am torn, as are you regarding if you will notice anything (well, in this case your better half, "presumably") by going to MC but I can assure from experience that all I seem to remember *is* my previous experience of MC.

If you say the word, we can even pull the trigger the same day and happily come back and report, at-least at the onset, that everything seems swell and great.
 
This article shows that the film thickness at the top ring increases as the oil grade increases from 40 to 30 to 20. The thinner oil grade has the thickest oil film. I do not know if this contributes to less blow by. I am using the 20 grade Red Line now:

Deposit Formation and Control in Engine Lubrication - Mechanisms & Models
Ian Taylor, Harold Gillespie, Richard Dixon, Bob
Mainwaring, Graham Smith & Steve Nattrass
Automotive Lubricants Group
Shell Global Solutions (UK)

Just before this oil change we were driving up and down the coast of Florida for 3 or 4 hours. At times there was some heated interaction with our neighbor’s Lamborghini Gallardo. The Bulls did not always play nicely. My guess is that we burned off the fuel that was diluting the oil previous to this period. At times the oil got up to 220 F but this is still not very hot.

I would hope to gain a less thick start up oil with the Motorcraft. There may or may not be any changes in wear. Plus I do believe that semi-synthetic oils may eventually be shown to be superior for every day use compared to pure mineral or pure synthetic oils (if there is such a thing).

Not sure about the Lambo engines,but the Nissan VG30DE engines do not like thin oils. My owner`s manual warns not to use a 5W30. Nissan FSM recommends a 15W40 up to a 20W50.

My smoothness and power was enhanced like night and day when I switched from 10W30 Mobil 1 to 15W50 Mobil 1.

So how does that beauty handle on high speed highway runs? I bet like a dream!

Wouldn't that be "This article shows that the film thickness at the top ring increases as the oil grade decreases from 40 to 30 to 20"?
 
I welcome the threads about exotics. Keep them coming, Doctor. I get tired of reading about these Camrys, Corollas, Accords, etc. We all pretty much know what sort of oils will work and how well in those.

As for how a Lamborghini behaves, THAT is not well-traveled territory around here. Looking at that picture, it appeared to be an automatic transmission. If so, I'm surprised at that. I'd have thought those would be manuals. Tells you how much I know about Italian supercars. Are they like AMG now, committed to automatic trannies?

Back to the original question, you've already established that it will run well with 5w-20 for street use. If this was being raced there might be an issue. I say give the Motorcraft a go and see how it works. By past analyses, it seems fine for the application. The Motorcraft oils do seem to give good results.

How about springing for a Lotus Elise. Now, THAT is a nice looking machine.

How did you get more power from going to a thicker oil? You could possibly gain power from going from a thick to thin oil but not the other way around. Your NA 3.0 DOHC would run fine on a 30 weight oil, my friend has a heavily modified 300zx twin turbo and he runs 10w-30 Amsoil ATM...

On further review, maybe that is a manual tranny. The gear shift looks like it would be a longish throw, if so. Interesting car.




It is a manual with a gated shifter. I think Italian exotics have always been somewhat known for their long shifter throws.

Doc,

Have you considered Torco SR-5 0w-20? If not, why not?



Does anyone have the viscosity rating of this oil at 40deg C? Their spec sheet shows n/a which is a little confusing. Their 5W-20 specs out at 42.7 @ 40C, which is the lowest I've seen to date.

Aparently you haven't paid attention to the fact that Dr. Haas has 5 times as many posts here as you do and generally his posts are very informative and focused on oils.

on the other hand, I can't say the same about you.
 
I think it would be great to try MC 5W20. It is a reasonably priced oil that has shown consistantly better oil analysis than any other oil.

Redline is kind-of a "fake thin" oil since it has such a high HTHS. It will be interesting to see how the Marcielago responds to a "real" thin oil like MC.
