"From 2021, Gulf will become the preferred lubricant supplier to McLaren Automotive, with all cars to be filled with Gulf Oil and fuel optimised for high performance engines"
That answers that question, then.
Hopefully they will still be using the same oil as Mercedes in the PU so they don’t suffer in the performance department.
It isn't a hope. it is in the rules. From
https://www.fia.com/sites/default/files ... -10-31.pdf
"7) No manufacturer may homologate more than two specifications of fuel and two specifications
of engine oil from their chosen supplier during a Championship season.
If fuels and engine oils
from an alternative supplier are preferred by a customer team two additional specifications of
engine oil and fuel may be homologated per customer team. A change of supplier is possible
in-season but this change will be considered as a change of specification.
The homologation will be valid for a maximum of one Championship season only, starting on
the date of approval by the FIA and ending on the start of the first Competition of the
following Championship season.
9) Each manufacturer shall submit an homologation dossier for each team it intends to supply.
There may only be one homologation dossier per team. With the exception of Power Unit
wirings, and fuel specification and engine oil specification if an alternative supplier is preferred
by the customer team, the dossier for each team supplied by a manufacturer must be identical
at any given time.
All power units supplied by a single manufacturer must also be operated in the same way, they
must therefore be :
i) Identical according to the dossier for each team, and ;
Unless a team informs the FIA Technical Department that they have declined any of the following, they must be :
ii) Run with identical software for PU control and must be capable of being operated in precisely the same way.
iii)
Run with identical specifications of engine oil and fuel, unless an alternative supplier is
preferred by a customer team (see paragraph 7) above)."
