Exactly.

If you say a mod gained you 30 mpg, that doesn’t really mean anything. If i have a different vehicle i will have absolutely no idea what to expect from that mod. Whereas if you say you gained 0.5l/100 km then that is usefull information for me. 0.5 l/100 km can be translated in to energy per unit of distance whereas mpg is a bit more tricky.

1l/100km (gasoline) is 9.1 kwh/100 km. From there one can calculate the improvement or waste for anything.

Its easier to calculate savings that way. Ex: 0.3l/100 km from mirror delete, 0.6l/100km from alt delete and i can expect 6.1l/100km if i do those mods to my car that consumes 7l/100km.

I am more familiar with it but typing “mpg to l/100km” in to google is not that hard. I get a number that is of no use to me without other data points to establish a relationship.
