Hi, I actually work in fuel system analysis. The one issue with the blog post that nobody seems to realize or point out. Is that fuel consumption is measured, and calculated internally as kilograms per kilometer. The change to volumetric units is done for the benefit of the population. This comes into play because namely, thermal expansion. Normally even in return less engines fuel is used to cool injector heads, as well as some body block parts (depending on engine design), as hotter fuel more readily reacts, and is already being routed to the warmed parts of the engine.
