In a multifamily unit the landlord is generally required to provide the water itself.

Among other things this is because water service is usually to the house and considered part of the house, not each individual unit.

The way you might have hot water included is if there is a single hot water tank for the entire house or for multiple units. You see this a lot in the houses that a further subdivided into small apartments. Generally speaking this goes along with heat being included though.

If your landlord said he would include hot water in the lease (even as a typo it's a legal document and you could probably get something) you could of course do whatever you can to get him to pay for the oil or some portion of it (I assume you have tankless hot water as part of the furnace) but with this comes looking for a new apartment because it will completely burn your relationship.

The law around hot water is similar to heat the landlord has to provide the means - this means you have working hot water heater. But he is not required to provide the fuel.

For the oil he can't mandate automatic delivery but he can put in there that you are liable for damage (frozen pipes, furnace damage, etc.) If you let the oil run dry. He can suggest that automatic delivery is a good way to avoid this.
