How to add Low Grade to the Static PumpJack

So i tried to copy and paste it and just change the short name that does not work so i need help

  "Static Quarries - Pump Jack Output": [
    {
      "Shortname": "crude.oil",
      "Skin": 0,
      "Amount Per Tick": 60.0,
      "Display Name": ""
    }

How to make it also give out lowgrade it should be 170 low grade and 60 crude?

Hey! Sorry for waiting i was on vacations.
 

  "Static Quarries - Pump Jack Output": [
    {
      "Shortname": "crude.oil",
      "Skin": 0,
      "Amount Per Tick": 60.0,
      "Display Name": ""
    },
    {
      "Shortname": "lowgradefuel",
      "Skin": 0,
      "Amount Per Tick": 170.0,
      "Display Name": ""
    }
  ],

No luck with that it either.

It must work, this is an part of the static pumpjack output.
It isn't virtual pumpjack from /qr, just saying in cause.

It works now thank you, the person that was trying to put it in the config file was putting it in the wrong location.
