What's the burn rate of our 6.0's (gph) while sitting at idle in the parking lot (or where ever)?

Just curious how much fuel I burn letting it idle for 20 +/- minutes in the morning (multiplied over time!).

Thanks!

 

me thinks it burns A LOT

I did a test this summer, coming out of the Eisenhower tunnel in Colorado put transmisson in neutral and reset MPG to 00.0 coasted for at least 10 miles, breaking at 80 mph a couple of times. suprised me to only see mid 20's on mpg meter

 

think I read somewhere that its like nearly a gallon an hour but I wouldn't let mine idle at all if I could help it

be

 

Why do you let it run for 20 min in the morning?

Not necessary at all.

 

It's called "remote start" lazy....
Probably more like 8 - 10 minutes now, but when winter finally decides to come south, I like my truck toasty and defrosted when I get in....

 

Since you let the truck idle alot, be sure and run it HARD once it is up to full temperature to burn off any deposits in the EGR system and turbocharger made by the low idle temperature.

 

Great advice - thanks!

 

I've got one of those Scan Gauges that has a GPH setting, never thought I'd need it. Now I'll have to look and report.

 

I'm not sure about GPH, but I've heard that 1 hour of idling is equal to 33 miles driven,
I'm Not sure if their is any truth to this,It's just what I heard.

 

thats true, but it relates to oil service interval.

 

Not sure about hard, strict numbers on the subject but I do know this- I was forced to leave my truck idling once for 9 hours (cold outside and had a faulty GPCM) and it didn't use a full quarter tank of fuel, so I'm not so certain about the 33 mile equivalent.

 

Matt was that at normal idle or the 1200 fast idle?

 

Normal. At the time I had not installed a high idle switch.

 

OK guys,when cold(coolant 55),idle at 800 rpm, it was saying 1.1 GPH.After I got to work and warmed up(170),and idling at 600 rpm, it says 0.8 GPH.

 

Were did you get the Scan Gauge??? During the winter there are times when my truck will idle for hours. When its -60 and you are hours from the nearest town you dont shut off the truck.
