If nobody told you, Would you know that was a motor?

Yes.It's not hard to tell that's an engine.

funny how they had to limit oil consumption in f1 engines....

I saw an article about that... controlled oil consumption to bring octane down.

They have minimum octane, not maximum octane...

There seems to be some controversy in F1 that some manufacturers are "leaking" oil into the combustion chamber to increase power. Not sure how that works. Seems counterintuitive.

My understanding, motor oil has a BTU component when burned, since fuel amount/flow is limited, the engine oil becomes a work around, and obviously they tune for it.

Basically due to very high rpm a lower fuel octane to speed the burn is helpfull, this is why F1 have a 'minimum' octane NOT a maximum octane. When oil enters the combustion chamber it effectively reduces the octane of the burnable fuel which is an advantage power wise to an F1 engine.

I don't think it is necessarily "burns slower" as much as it is that they had/have been running the engines on controlled detonation, since they were finding the burn speed limitations of gasoline-ish fuels. If you can't get it to burn fast enough, make it detonate!

They have a MIN octane as the F1 guys want lower octane than they are allowed. So use the control fuel then 'add some oil' and they get the lower octane they want.

I wonder if they're getting a good even burn across the chamber with the oil in there.

I personally think that they are more likely to burn the oil in the exhaust port and manifold than in the combustion chamber. Oil in the combustion chamber is a bit difficult to control as it cause preignition. In the exhaust manifold, it can be used to run the turbo, which has the electric recovery system attached to it.

When did 50% become "more than half"?

When someone says "up to 50% or more" :evil:
