Oil & Fuel TN65 - high fuel consumption

redneckford · Jul 20, 2008

Are they really burning more gallons of fuel are do we need to double check the volume measurements that we are using. (Faulty Fuel Pump Measurements at fueling stations is what i was referring to) I know you have a hard time understanding my jiberis but kind'ove like a glass of water and ice--one volume---and then run it into a blender--gas pump--- and you get more volume but no more water or ice just more air mixed in. (After it has time to settle-in your 55 gallon drum---back to the same volume measurements--45gallons--however the pump measured 55 gallons of material passing thru) You pay for 55 gallons of fuel but only have 45 gallons. Hard for me to understand how the dried out fuel, sulfur removed, is taking more "gallons" to run the same engine at the same rpm if the diesel fuel is "spraying" into the cylinder correctly and the external temperature is the same. Sorry just worked on alot of 3 and 4 cylinder Fords in the last 30 years and think something else is going on here. Drier Fuel May be causing the injectors or pump to mis apply fuel due to the dry content. (We may need to recalibrate older injection pumps and injectors)Maybe more unburnt fuel discharge? But I thought that the dried out fuel was suppose to cause less pollution not more. More fuel to do the same amount of work sounds like more pollution to me not less. Many of the old fuel station pumps can only work if the price per gallon is less than $4.00 per gallon!! I could get into the molecular structure of high sulfur diesel and low sulfur diesel but i think that would diffently get my post censored!!!

IOW, it's got nothing to do with tractors burning more fuel.

fuel measured in gallons or pounds??????

Now that I think about it more carefully, my fuel consumption has gone way up. I can't say positively if it is due to my engine running so badly or the fuel. I have found out though beyond a shadow of a doubt that our off road supplier is using ULSD now though and has been for about 3 months.

About the time my engine started dying all the time. Nobody has been able to figure it out. I have had to put the thing to work though durring it's short visits home and the fuel consumption went way up. I uset to be able to mow 10 acres before I even saw the needle drop and lately it has been so bad that it's down on 3/4 before I get 3 or 4 passes around the field.
My pump has been rebuilt too. It SHOULD be right given the reputation of the shop that did the work on the pump itself. They have done a lot of pumps for me over the years and never messed one up.

I fill my tractor from my own tanks, to the same point every time. Yet I can't get as much work done as I use to.

And in New York we have the Division of Weights and Measures which monitors and certifies all the pumps and scales in New York (except for on the reservation). So every year (I think it is each year, maybe every other year) the pumps are calibrated and stickered if they pass.

IOW:

a ton of feathers and a ton of lead both fit in your fuel tank!!!!

They're getting us both ways - Raise the price of diesel fuel, lower the efficiency of diesel fuel. In effect, instead of $5.00 a gallon for diesel, it nearly becomes $10 a gallon.

Think I'll drive my tractor down to the local greasy spoon and fill up on vegetable oil.

Try buying Bio and see how much it costs. There was a supplier here that made different blends up to B100 and it was so expensive due to feed stock prices that they were forced to shut down a few months ago. I think in April. It had gotten to 10 bucks a gallon out of the pump for B100.

Egads...it used to be free; well, sort of.

I really noticed the high fuel consumption when I drove the tractor to my farm on a back road (12 miles); hooked up the brush hog, mowed the edges of the fields and was done a few hours later. Last week, started out from the house with a full tank of diesel. After the road travel and brush hogging, the fuel gauge used to display just a little under Full. Now, it registers between a half and 3/4. I thought it was leaking fuel.

On another note, I noticed the black smoke coming out of the exhaust pipe; it never did that much before. I wonder if the fuel is causing the smoking exhaust. Only have 736 hours on the engine and the filters have been changed more often than necessary.
