I have a friend who work in the lubricant industry and he told me that oil companies will sometimes sell other oil companies their lubricants/fuels and allow them to re-brand it at a price. Maybe this will happen - not sure Castrol/BP is so advanced with these fuels?
castrol is in road cars in my opinion the best engine oil.
Why?
Oh we don't want to go down this rabbit hole, trust me. For road cars, lubrication has come on leaps and bounds, even the short trip taking, extensive idling, maintenance ignoring granny is pretty well protected with your off the shelf "synthetic" oil. And even if Castrol isn't a true synthetic in the strictest sense of the word, all of my street Hondas happily go 10,000 miles per oil change and most of them have well north of 200,000km so I can't complain.
Then again racing oils have completely different requirements than conventional oils, they don't have to deal with condensation, or fuel dilution, or long OCI's. Putting in racing oil in a street car will actually ruin your motor, and street oils probably wouldn't work as well on track as a dedicated track oil.
In formula 1 the oils are pre-heated and injected into the engine, thus there's probably no need for multi weight oils with various VI's. The environment has much tighter tolerances, and smaller clearances. It's certainly an interesting topic, but one that's shrouded in much secrecy.
