Seems odd you would get a reliability upgrade on fuel.

[johnny comelately]

This is fully in line with what I had said some time ago regarding renewable fuels and the many ways you can tweak them even after they have been homologated.

You can't tweak the chemistry after homologation.

In my uneducated opinion you can tweak the chemistry within the parameters given by the FIA at any time. And that would allow more aggressive mapping, its a win win.

Seems odd you would get a reliability upgrade on fuel.

If it knocks the hell out of the engine and do stuff like wash away the oil film then I could see teams get away with it.

Technical regulations make no mention of any reliability upgrade to fuel. Let's assume there is a section that allows it, which is not apparent. Still, other teams have to agree to the explanation given for the upgrade, that can correlate to past reliability issues. Remember, reliability upgrades need approval from other manufacturers.

Fully agree re-technical regulation where it concerns fuel. It sounds incredilous to suggest that a reliability request change for homolagated fuel formulation will even be pushed forward let alone accepted.

It would be easy to make a ‘good’ fuel knock and bore wash though. Simple. A change of a few injection maps and a few extra degrees of timing would make a knock situation.

You could have the ear fuel in the world and shoddy mapping could easily kill a engine through bore wash or knock/detonation.

FIA will have the maps to discern. And they have fuel tests too.

Unfortunately they might ask the team to revert to lasg years fuel instead of making a new one!

Bore wash at 1.2+ lambda and direct injection !
Really

[Big Tea]

They could possibly 'claim' that there was a more efficient or greener way of producing it with this formulation. Or that some of the 'old' components were no longer available or green

Yeah, would be so easy to tweak the map for it.

I do wonder how quickly bore wash would occur in a race engine such as a F1 car. I know a bad injector or fuel can quickly cause problems with piston ring lands through supersonic detonation/soundwaves from the direct injection so if the wasnt a optimised burn then it can quickly become bad.

Ah yes, the brilliant FIA....master fuel detectives

It is last year's homologated fuel composition which was homologated on 1st March 2022 that they will be using this year and till the end of 2025 season.

with latest rumors saying the W14 having delay it's gonna be W13 part 2

It was mentioned in that article that there was a late design change.

It's like we entered a parallel universe where Mercedes is running right up to the wire, and Red Bull have already done their shakedown. Normally it's the other way around.

A late build like this is highly unusual for Mercedes.

could mean a change in concept again after the other one not working
