275 gallon oil tank - how long should it be between fill-ups?

My 27 year old Carrier has the proper nozzle size listed on a spec plate just inside the cover. Almost every guy who serviced the furnace used the listed size (but one guy didn't. I wish I'd paid more attention>.)

Joe, I'm in Putnam CT. I filled up a month ago and I've used about a third of the tank so far. I"ll be filling up again in February. My total use is about 800 gallons a year.

I too was offered $2.70 something by Saveway and I declined, fortunately. I bought from Dollarwise and paid 2.039. Dollarwise has a network of local dealers for cheap prices.

That would be my typical expectation, and a little extra to insure proper flow from the large tank.

Yes, but that is rather easy, especially if it's a gravity feed setup.

Of course.

Very, very, very wrong. Diesel stores much better than gasoline. At least a year "as is", 2 years or longer if you put diesel Sta-Bil in it.

Certainly replacing the gauge is a good idea.

Good if you have your own forest, otherwise you have to figure the cost of the wood vs. the oil it offsets to find your real savings.

I gotta come clean and tell the truth. I swiped that from a tag/sig line used by a guy named Gunner, a frequent poster to rec.crafts.metalworking.

To quote him fully:

Political Correctness

A doctrine fostered by a delusional, illogical liberal minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

Take the fill cap off the tank and put your penis in the tank. When it begins to sting, you hit oil........... Oh, wait a minute....... Your penis is way too short.......

Use a broomstick and measure the depth instead.

Hi Charles,

Earlier this week, I posted a copy of my fuel oil records here:

Today, Scotia Fuels filled my tank, so I thought I'd bring you up-to-date. Between September 8th and today, I used 193.9 litres of fuel oil (51.6 US gallons). That works out to be 1.55 litres per day (0.4 US gallons/day).

The bulk of this would be related to domestic hot water production, with the balance consumed as backup heat to my ductless heat pump.

To add further context, Halifax, N.S. has 4,367 C heating degree days (7,861 F), whereas Buffalo, NY clocks in at 6,693 HDD F.

Cheers, Paul

It's a bad idea to let your tank get real low especially where it's so old. A lot of sludge will be drawn into the system. I would not let it get below 100 gallons to be safe. I have a .85 nozzle but the furnace still uses about 1 gallons/hour. I have a timer connected to the furnace so have a good record of my usage. I normally use about 3 gallons a day during December, January and February so in 60 days I would be down about 180 gallons. I plan to get filled up tomorrow (last fill was Nov 1st) and I expect to need 100 gallons. I have a pre-buy at $2.679 so I will pay the cash price instead which is 30 cents less.

I drove by a local dealer in MA and his posted price is $2.26 today. Call around and you may do better as one of the guys at work just paid 2.01 but he bought 400 gallons. I'm sure glad I opted not to go with a contract price as it was 2.75 this season.

The nozzles are rated at 100 PSI. A lot of newer two stage burners like Riello operate at 140 PSI at their high fire rate so you have to add a correction factor to find the actual flow rate. Even an older burner may not be operating that the rated 100 PSI. Pressure gauges are cheap and easy to install.
