5.75 mpg yest. 7 mpg today ???????

yup!!!! hit the nail right on the head

 

My company doesn't do idle percentages they said I can idle all the time jokes on you

 

mine doesnt either we can idle all we want but only a fool doesnt look at the fuel reports. they can tell how much fuel u burn and pretty much narrow it down to how much u idle thats IF u dont have a quallcom linked in to ur ecm if thats the case the computer tell them everything they want to know.

if you as a driver have 30% idle time while the rest of the fleet only has 10% as an average it is only a matter of time before u get a phone call telling u idle less or we will find someone who can. fuel surcharges and discounts aside diesel is roughly 3.80-4.00 a gallon thats a lot of money to just let someone who doesnt give a rats ### just to burn away while they are inside eating dinner on a 60 degree nice day

like i said i idle i've told my boss I will not freeze for anyone and i will not sweat my ### for anyone if im cold i will idle if im hot i will idle in between i dont period my boss totally agrees with me and has never said a word about my idling practices

 

One thing to consider is fuel quality. I am always looking for lower priced fuel, but several months ago that came back to bite me.
I saw fuel advertised about 25 cents a gallon less than other places at a fuel stop I had never used before. Got around 300 dollars worth, and my mileage was off nearly 3/4 of a mile per gallon that week. After I got the cheaper, off brand go-juice, the truck ran terrible with no power. Did not find water in the filter, but just ran sluggish until I burned it all out.
Sometimes cheaper ain't better. You get what you pay for.

 

Depends on wind, road conditions, terrain. At 62, you may have been "lugging" your truck. Kinda like staggering along. Hey, if you get better fuel mileage at 75, do 75! Just watch for the smokeys!

 

Well 2 things ... For the duration of the first leg, you climbed almost 5,000 feet. But once you got to Colorado, you were running in much thinner air making it easier to push through the air and of course you're at a nice altitude the duration of the second leg. Any time you're running above 4,000 feet you're in a prime condition for MPG. But first you have to make the climb up out of the lower plains.

Also, we have no way of knowing what sort of winds you we're dealing with the 2-3 days.

 

Sorry you arent "bright" enough to pick up on the fact I was saying it's people like you with that mentality as to why companies have idle guidelines and try to save every drop of fuel they can..............

 

I'm running from spokane wa to billings mt with a 3406e that i had tuned to about 650hp and i'm getting 7 mpg that's over and back,and i'm running around 68mph,before the tune i was doing 5.14mpg,and i always thought people where lying when they said they where getting 7,but now i'm a believer(also a believer in Jesus)in saving fuel...

 

Altitude, wind, road elevation, speed, temperature etc... are all factors in which can affect your mpg! Even the time of day! Not only are all these factors but also your truck comes set from the factory and is programmed to run the best mpg at a specific given speed. Different companies set up their trucks differently. Depending on where they run, what they haul, what their governed at etc... Your truck maybe programmed to run better at 65-66mph then 61-62mph.

This is all great learning curve for when you are an owner operator! Keep doing what you are doing by keeping track of your mpg and how you run and you will make a successful owner op one day!
