off road diesel. many gas stations have it. avoid on road diesel only difference is it costs more. you would have to pay the tax. if your tank is outside. mix in a little kerosene.
Furnace pumps fuel depending on nozzle side. .5 gallons. 1 gallon per. and then depends on how often it kicks on (size of your house, how well insulated, hot water off boiler if coiler boiler etc).
But safely, you shouldn't be burning through ten gallons of off road in a a day and half two days. put in five gallons if they can deliver next day, ten if you are a couple days out.
don't trust the float on the tank, they stick. if you put in ten of offroad, and a couple days goes buy, unscrew the float cover and pull it off. push your finger down on the actual float and see if it has much movement. should give you a idea at least if you are about to run out again. If the furnace does run out of oil. you will have air in the line. hit the reset button, sticks up right in front of it on the burner. cant miss it says reset. if it starts and dies, it means it got no fuel. air in line. get a wrench, turn little nozzle where line goes into burner counter clockwise. put coffee can under nozzle. hit reset button again. you will hear air hissing out of the nozzle, it will slowly start to push out the diesel. Do not close the nozzle let it go into the coffee can UNTIL it stops hissing and you see nothing but diesel and air coming out. Then tighten nozzle. if furnace kicked off again, hit reset button again. see if it ignites. if not. do it again. nothing comes out of nozzle. your filter is clogged. More you run out of oil, more of the crap from the bottom of the tank runs into the filter and into the furnace.
get there, let me know ill see if I can explain that.
offroad diesel, if outside, mix a little kerosene in. ten gallons. two days. check float gauge.
off road diesel is about the same price or cheaper than heating oil. and the same thing.
keep in mind your furnace shouldn't run all the time. Don't assume something is wrong just because it isn't running. crank up the thermostats, see if it kicks on. or check the boiler gauge temp (should have on it ) . unless cold start it will keep up to temp kicking on and off intermittently. they don't run all the time.
kerosene is only if the tank is outside. outside tanks get cold. the #2 gels so you run kerosene and a additive to prevent gelling. for your sake, ten gallons or so. couple days. you can dump in a gallon of kerosene for every four of offroad diesel it will survive. or just use straight kerosene and no diesel but it costs more and you probably wont need it. If it isn't outside. don't use any kerosene. just the offroad diesel.
