Do I take the risk?

Well I have not done this in a long time.

My onboard gadget tells me that I have fuel for 23 km.

Consumption rate now is of 15.8 l/100kms

I live 19 km from work and there is a gas station at the corner a few streets before.

I don’t now the limits on my truck so…Do I risk it?

If there is no heavy traffic on the way home I could drop the consumption to about 14.5 what would get me a few more km. But if there is a lot of traffic I could run out of fuel.
