I thought they flew a technician out from France.

Bugatti of North America has several dealerships in the U.S. and routine maintenance can be done at any of the service centers.

There is a rather massive difference in terms of architecture between a turbine, which has no parts going up and down as the shaft goes 'roundy-round, and a piston engine, which has many parts doing the hokey-pokey as it spins the crank about.

I still belive it would run nicely on rotella...
but if going by factory oci it would mean that you would dump
perfectly fine oil at the changes.

The Veyron uses special Michelin PAX tires found on no other car. They were designed specifically for the Bugatti's capabilities and can only be removed from the wheels in France, a process that costs $70,000. The tires themselves cost $17,000 per set.

Quoted from Jalopnik.

This was also quoted back in 2010. I am sure bugatti North America does theioil changes. Maybe the tires too by now who knows.

Okay, so the Bugatti-badged VW is apparently exempt from the need to provide for adequate oil cooling?
Got it.
Of course, this engine will rarely if ever actually produce anything close to a thousand horses even in the hands of its most psychotic (or inebriated) owners, but I guess that doesn't matter.
I guess that nobody else remembers that really thick grades are often recommended as band aids.
This VW design is no different, despite its undeniably exotic design and unparalled performance in a street car.
Heck, it'll outrun most purpose-built race cars.
I can't think of a modern purpose-built race engine that needs a sixty grade oil, though, and they actually do get run hard all of the time.

Audi has the special 501.01 spec for the R8 GT (a higher output and lighter version of the R8 V10). The only oil on that list is Castrol Edge Professional TWS 10w60.

Clearly VAG believes it is necessary to run a 60 on their very highest-output motors. I have to assume that on something like the Veyron, this was tested heavily and 10w60 was deliberately chosen. Castrol also provides their service fill so naturally TWS was the only option.

I strongly suggest you read up on the car's development.

It has multiple oil coolers. Adding any more would have required more grille openings, which would increase aerodynamic drag, which would have required more power to achieve the top speed, which would have generated more heat...

There's plenty to criticize about the Veyron, but the competence of the engineering behind it is completely beyond reproach.

It says Bugatti approved Castrol 10w60, but what makes it different from the Castrol 10w60 used in certain BMW models?

I don't doubt that this car is a remarkable achivement and it does take a lot of power to push 4000+ lbs to the speeds the car can reach.
Maybe the VW folks should have spent a little more time on weight reduction?
With all those cylinders and turbos and all of the complexity, this engine has a specific output only slightly superior to the simple two liter inline four used in the original Honda S2000, for which any API 10W-30 is recommended.

I run a turbo S2000, with 385-407 RWHP, depending on boost levels (summer-winter) and 8500RPM redline (2.2L)

One thing has become clear, 5W-40 is not sufficiently viscous to protect the engine. The loads require 15W-50 especially during the summer.

I'm not at all surprised by this engine's requirements. It's what us turbo guys have been doing all along. Doing otherwise results in rapid wear.

Remember, non boosted engines have vastly different bearing load issues. Also, consider what's required for track days. Many high powered and turbo track cars simply don't hold up with thin oils, unless designed to do so.

If you're getting that kind of RWHP, would it be fair to say that the engine would dino at 200 bhp/liter?
Quite a bit for any street car.
I understand that forced induction will result in higher bearing loads and that more power output requires that more fuel be burned which in turn generates more heat.
What kind of oil temperatures are you seeing?
What's been done to the engine to help it to hold up under power levels way beyond what Honda envisioned?

Indeed. Far beyond anything they were tested or designed for. And when a simple upgrade in oil can hold them together easily IF the tune is good, why not?

Nothing. It has the same name and is the exact same oil.

Race engines are rebuilt every few hundred miles and longevity is not a factor.

Performance is.

I assume everybody would be saying this was a great idea if the Veyron was designed and built in the US.

This thin oil or you're obviously rubbish mantra is getting a bit old.

I await the first Veyron owner on Bitog to post up a UOA on 0w20 after 5k miles.

Wonder what the wear will be like, if the engine hasn't grenaded that is.
