is this good for a fuel range

Hey I have a vs commodore exeutive series 2 and I ran my car too 500kms before filling up now the fuel light came on at 470kms and when I fill it up I pump 50L in her she clicked at 48.89L so I slowly pump till I hit 50L so is that good for a old girl as shes done way over 320999kms so my reading is 100kms per 10L your thoughts guys?

It'd be around 40-60 km's remaining as soon as the light comes on, around the 500 km mark to a tank isn't to bad for an old ecotec.
Don't fill it slowly and squeeze as much in as possible, over filling like this will flood the vapor liquid separator and the carbon canister as both sit lower than the fuel filler.
