What weight do you guys think the F1 cars use?
Formula 1?

It's really thick. The engine needs to be warm even when its off or the oil doesn't flow. Not sure about the weight. They use lines circulating hot water at around 70 degrees or so till its time to start the engine.
I thought it was 0W.
https://bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=71544 gives some information from back in 2004. Generally speaking I've also heard they tend to use more viscous blends than in use on the street, Castrol TWS 10w60 or Mobil 1 15w50.
IIRC the reason they have to circulate hot coolant through the engine is due to the tight tolerances and design for running at operating temperature - the engines are effectively locked up solid at room temperature.

Talk about a tight motor!

Slightly older article, but it again supports the theory that Shell motor oil is being used:

But yes, I would agree that the formulations are being created for each engine and the specific conditions. It is doubtful they are pouring an OTS oil in there.

Near the bottom of this page, Castrol reiterates that the fluids are specially developed:

Thin is in - - even in F1. Browsed a book on Ferrari F1 a couple of years ago and it was mentioned that their engines used 5w30 during the race and 5w20 for qualifying. This article mentions trend to lower viscosity in F1 lubes -

The very informative posts of Doug Hillary have mentioned the various engine lubes being used at the ADAC 24 hrs of the Nurburgring (24 hr race for touring cars like BMW's, Audi's, VW, etc.). The Castrol-sponsored teams used Castrol TWS 10w60 (partly because of fuel dilution over the long distance). He did mention,however, that some teams were "experimenting" with 5w20 oils!
