Energy Dashboard -> Adding Oil usage

Regarding the Energy Dashboard. There is electricity, gas, and water, but I miss the oil consumption. This should be able to be specified in liters. Actually, one could minimize the effort and rewrite the water logic to oil (should be mostly copy & paste). In the forums, there are countless entries where people somehow cobble together a solution that displays the oil consumption.

I think it should be included in the Energy Dashboard, just like gas and water are already present.

There are plenty posts about that already.
Like this one, which also suggests to add kWh as heat.
