Blackstone propane vs natural gas

If your town has a natural gas line, you should use this feature to fuel the Blackstone gas grill for your backyard grilling adventure.

Let’s see the Blackstone propane vs natural gas difference.


Often your neighbors will have pointed out that there is no difference in performance between propane and natural gas grills, in fact, it is a common thing but we are talking when the outside temperature gets as cold as -45F.

In this case, the performance of propane is hindered because it cannot vaporize, but this is not the case with natural gas. Propane and natural gas work in a similar way.


If you’re using a propane gas grill, you’ll need two tanks so you can use the other one when the propane gas runs out. Sometimes the gas runs out in the middle of cooking.

But if you’re working with natural gas, you don’t have to worry about running out of fuel.

Cost Effects

A 20-pound propane tank costs you $40 to $50, and it is possible to exchange a full tank in some places, such as most major grocery, hardware, big box stores, and some gas stations. And the cost of refilling it would be expected to range from $3 to $5.

Natural gas is usually $.50 to $2 per therm which is billed plus you will incur additional monthly maintenance/administrative fees, but still good.

Overall – Blackstone propane vs natural gas

  1. There is no performance difference between propane and natural gas, except in extreme cold.
  2. Natural gas gives you more convenience and never worry about running out of fuel which is a big difference.
  3. Choosing a gas fuel ultimately depends on what fuel source you have access to and what the costs are in your area. If your city has natural gas pipeline then it should be used which is cost-effective which is another big difference.
