I hear yuh, my fuel gauge comes to life just over 1900 rpms.

 

my fuel gauge likes to see 1/4 tank more than it does a full tank lol. I think I've gotten better fuel mileage this tank of gas just from the driving on longer trips some here in the past few days. I've gone 180 miles and I'm sitting just at a quarter tank. that's better than what it's been doing lately, and compared to last fill up.

 

Same here, well just about. 1/2 tank comes real quick. Then it takes its time for a bit, - like a pause. 60 miles later it hooks a boat anchor.

 

Mine usually gets 110 before 3/4, 180 at 1/2, 240 at 1/4, then it's got a light on at 300.

It's not accurate - but at least I know what to expect.

 

From what I recall 300 miles isn't bad? 12-13 mpg?

 

I'm at 175 on a half a tank. This tank has been awesome in gas. I'm thinking we got summer gas again

 

Around here the speed limit is 75 for the most part. With the 33s and a 3.55 rear my keeping up skills were sub par. On the flats though, I could cruise at 100-105 all day long.

 

I dont even watch the mileage much anymore. I just wait for the idiot light to come on which happens once a week.

 

I usually don't let it get below 1/4 tank. I don't keep mileage, once in awhile I'll reset the miles. Always in the 200's when filling up again. That doesn't say much. At least gas has been cheaper for awhile now. It was $75 every fill up for awhile there. That's gone down quite a bit thankfully...for now anyway.

 

70 here. I HAVE TO use cruise or I'll creep over 80 pretty quick. Quite a few cruise 85 around here. Ticket territory above 80. Are you able to cruise that fast, 100-105 without getting pulled to the side ? Probably not what you meant lol. If I recall some of these trucks have limiters...90 something?
