The oil mist is simply burned. The power in Q is limited by the limited fuel flow and additional stuff to burn means more power. This has nothing to do with lubrication.hardingfv32 wrote: ↑23 Jun 2017, 18:15We still do not know how these only vent/vapor system provide their benefit after the oil mist is in the intake system.
I would simply increase the number of light hydrocarbons. They give a nice, well burning mist and are common in motor oil. Nothing to do against this.hardingfv32 wrote: ↑23 Jun 2017, 18:15If there was some kind of chemical not common to motor oil beginning used the FIA could have banned it and similar substances form the oil's composition.
FIA has now stated explicitly that the use of chemicals in oil that could help improve combustion is not allowed.hardingfv32 wrote: ↑23 Jun 2017, 18:15If there was some kind of chemical not common to motor oil beginning used the FIA could have banned it and similar substances form the oil's composition.
I just watched Ted's Notebook and it sounds like Ferrari did indeed have a second tank with a different type of oil that would combust well.Stargazer wrote: ↑24 Jun 2017, 00:21I just read a speculation on one of news sites that Ferrari uses 2 oil tanks filled with different oil. New oil tank is the one appeared in the floor of their 2017 car. And that the second tank has a special oil for the "oil burn" purpose. It's also stated that the latest 2017 regulation changes in this area were likely caused by Merc's request to FIA aimed at trying to slow down their rivals.
I think the point is that the second tank contained 'lubricant' that was engineered to be useful as fuel. If you look at the wording of the technical clarification it seems pretty clear what it is designed to prohibit. These clarifications do not just come from nowhere, unless something was going on the FIA would not bother to do it.hardingfv32 wrote: ↑25 Jun 2017, 08:301) Name a chemical that would make a good fuel AND work as a lubricant? The latest lubricants have very high combustion temperatures. As an example they can make it through a CAT without lighting off.
2) Current lubricants provide a big reduction in friction…increase in power. It is going to take a lot of combustion energy to make-up for any loss friction reduction from an inferior lubricant. In other words this is a compromise.
3) Exactly how would you use a second tank of oil? Do you think they can just change oil formulations on the run?

Maybe the oil works as a way to reduce knocking allowing more aggressive engine settings for longer. Or maybe the oil is burned in the exhaust for extra turbine power.hardingfv32 wrote: ↑25 Jun 2017, 08:301) Name a chemical that would make a good fuel AND work as a lubricant?

They still do, that Facts Only guy said it's because of a turbo seal issue.
