I think the fuel didn't change, from what I can see, so I'm not sure.LionsHeart wrote: ↑02 Mar 2024, 19:45
A thought occurred to me this afternoon on this subject: maybe it's the fuel. The more ethanol in the petrol, the less power for the same compression ratio. Maybe different engines tolerate more and more ethanol in petrol differently. If I remember correctly, every year there is less and less fossil oil in fuel and more and more synthetic oil. Of course, this is just a guess, but the general trend kind of hints at it a bit.
In other words, engine power is going down a bit.
