I don't know if the OP's quoted figures for NG CCF includes the delivery charges averaged in or not, but those must be calculated in as well to get a total cost. Where I am, oil is cheaper than NG and LP.

John, in 1982, I was requested by a local newspaper (Riverdale Press) to give the pros and cons of natural gas and oil.
From what I remember, it was Oil you pay for before you use it, gas is paid for after you use it.
Oil, you can negotiate prices, PLUS they give you a service contract for about $100 a year.
A utility such as Con Ed will require you to pay their non-negotiable price, or you lose service
Oil is toxic and expensive to clean up. Gas leaks can cause an explosion.
Oil companies' service agreement means they will come 24 -7
Oil has to be delivered, and in some localities, it is not possible because of snow accumulation
Utilities are NOT allowed to make service calls other than for a leak, as it is "unfair utility competition," so they will say, "Call a plumber."
After the Riverdale Press printed pro and con on both sides of the middle of the paper, all my gas requests to the utility seemed to have gone missing for 2 months.
The problem is that some utilities used to rent a water heater or boiler cut off service if the client didn't pay.
If a plumber leased a boiler or water heater and the account did not pay the most, we could file a mechanics lien and wait a year or two before going to court
Oil is cheaper because #2 oil has a BTU rating of 138.000- 140,000 per gallon
A cubic foot of natural gas has a BTU rating of 900 -1,200
Propane is more dangerous than other types of fuel as it is heavier than air, forms pockets, and is highly explosive
The oil-fired boiler needs service yearly. filters, strainers, nozzles
Gas is cleaner and could go years without any service.
