Fuel consumption CT450?

[HK45]

Do you guys with CT450 go through alot of fuel? My machines seems to drink it like no tomorrow. I have a backhoe setup so i know the machines weights more to move around, But Im going through 4-gallon every 2 hours it seems. That is running almost full throttle and driving around and stopping and using backhoe. I do run an additive every few fill up's and don't know if that can kill the mpg. Also i have no fuel in the oil so its burning it up. Any idea's or is that normal?

Not a 450, but my 235 burns pretty much a gallon an hour.

The Daedong 4B243 has a published SFC (specific fuel consumption) of 192 g/hp-hr @ 2600 rpm.

That equates to 3.04 gal per hour when producing 50 hp @ 2600.

A consumption of 2 gallons per hour would represent an average engine output of 33 hp @ 2600 rpm.

My 225 @ 27 hp burns between .5 & .75 gl/hr. Usually running 2000 - 2300 rpm. but engine seldom if ever lugs and no BH to carry around. I am always working in low range, mid-range for getting from point A to B on the place or occasionly with rotary cutter in easy mowing conditions (high range works only for getting down the road). You have almost twice the HP as mine, probaboy work it harder so seems your fuel consumption is in line. Regrettably as the EPA continues to tighten up on exhaust emmisons the fuel consumption rate on these engines keeps climbing. Don't know why but the cleaner the fuel burn the more fuel engine consumes. Go figure!!!

Yup the EPA will kill diesel's off. I have a 2002 duramax which i use to pull my machine around. I will never give it up since it has no emission on it. Thats also why they get the best fuel MPG out of the duramax generation.

Agree that the government regulations to improve exhaust emissions continue to increase fuel consumption.

There needs to be a balance between the two.

Hopefully those that vote will someday demand politicians show the business case between all things. In this case, the further improvement in exhaust emissions vs the cost of equipment and the operating expenses we pay.

Do you have the SFC for the CT235?
Appreciate any help here.

My Kubota B3200 goes through roughly a gallon an hour at around 1800 RPMS with the BH attached.

my CT440 goes thru about a gallon an hour running hard and brush hogging. yours seems to be a bit excessive to me.

Attached is the engine performance curve for the 3A165 engine.

The SFC is 195g/hp-hr @ 2600

Your peak output of 34 hp @ 2600 would consume 2.1 gph, ironically right about where the OP is averaging with his CT450.

It looks like some of the information I saved from last year's tractor shopping might be useful after all.
