2010 RRS gas mileage

Thats a joke right? Dude I get about 220-240miles out of my entire tank...averages around 13-14mpg. I think my sisters 2008 HSE gets better mileage.

must be a joke - i do LOVE my '10 RRS, but i'm pretty sure my 2002 F150 got better gas mileage (and at least that took the cheap gas). seems like I fill it up, i drive home, go to work, run an errand or two then fill it up again - many things to love about this ride, gas mileage not one of them

been averaging 17.6... got 3000 miles on her now. steady freeway to californina when she was still quite new was 20.0


keep your foot out of it and it is pretty respectable for 5470 lbs

Now that its not zero degrees and in the low 40's, I got 16.5 on the highway doing 75 or so in the Pocono's..... :mrgreen:

The last two vehicles I had I bought brand new. Didn't reach full gas mileage until over 10,000K. My 2002 Denali would barley go 400kms when new. Eventually it kept getting better and ended up at 520kms per tank.

One of my friends has a 2008 RRS HSE and a 2008 Escalade. On paper they should get around the same mileage but he finds the RRS much worse. He figures it is because the RR is so much more fun to drive, he adjusts his driving style accordingly and ends with his foot pegged to the floor far more often then when driving his Cadillac “tank”.

I get about 850Km's (510 miles) to a full tank on the highway doing 110-120km/hr (66-72 mph) on cruise control.

There's a reason they are called an Escalady `)

I took a long roadtrip across the state and back this past weekend and averaged around 14mpg highway doing between 80-100mph.

My 2006 got 14.5 around town and 17.5 on the highway.

My 2010 is one month old w/ 650 miles, all of my driving is in town w/ 1-2 miles to and fro work and I have been averaging 10 mpg, yesterday I took a 220 mile road trip and got 17.4mpg. The service manager at
my dealership advised me that it takes a few thousand miles for the mpg to settle in.

On the bright side, my gas station allows me to use my food stamps to buy gas and as such I don't feel so bad about wasting the fuel when I am racing from stoplight to stoplight to hear the roar of that new 375 hp engine.

FYI, The 2010 is overwhelmingly a better truck than my 2006, the ride is better, power is better, sound system is exponentially better, GPS is better and on and on and on and on…...

Does your vehicle even warm up by the time you get to work & home again? From what I've read and researched even engine oil takes time to "activate" to start really protecting your engine, that the additives don't really kick in till about 500-1000 miles because its heat that activate them. So your engine may take even longer to get the full protection of your oil.

Yes the engine gets warm, but more important the seats get mighty toasty on the 2010 and the great thing is the butt warmers stay on unlike the older models.
