#166 of 185 2005 8.1L Sub 2500 4X4 by busto

Jul 30, 2007 (6:17 am)

getting between 9-10 MPG around town, about 11 MPG highway. Using synth blend 5w-30. 3.73 rear. Very easy driving, no lead-footing, no jack-rabbit starts.
 
Is this typical for this model? Runs terrific, but I'm getting ready to take it in for service with this fuel economy... sticker says 13/17!

When my Yukon was brand new, I was getting just a hair under 20MPG highway and around 17 City. Now that I have 144,000 miles, I'm getting about 17.5 highway and 15-16 city.
 
I drive very gently - believe it or not, I'm on my ORIGINAL set of brake pads with 144K miles! Every time I go in for an oil change or a yearly inspection, I ask my mechanic if it's time for brakes, and the last time he looked, I was still at about 40-50% pad in the front! Unbelieveable.

#169 of 185 2007 Suburban, is my mileage normal by spyla

Hi, I have 2007 suburban with 2100 miles. It currently giving me 11 miles in town and 16 on Highway (avg on 600 mile trip on I-10) per gallon. Is this normal? I have a friend who has 2005 suburban he gets 19 on highway and 14 in town.
 
Any advice?

hello spy-los-angeles, my advice is to get a credit card which gives you 5% cash back on all fuel purchases . one that works for all brands. for example, chase rewards card (max $300 per year). some hotel-cards (hilton) will give ~5% back in free-hotel-rooms, in case maybe you travel and can use that as much as cash. also your new suburban mpg might get *slightly* better by the time it has 10k miles.

Just over 1,000 miles in my Tahoe, so not a great sample size to choose from, but I have been getting right at 20 mpg on the freeway by keeping the cruise control on as much as possible (which maximizes AFM mode) and keeping RPMs below 2,000 - that usually has me between 70 and 75 mph. Around town I've been getting 13-14, and right now I'm averaging 17 on a mixed driving tank.

My '06 Suburban 4x4 with 5.3 engine and 3.43 gears gets consistently 20/21 mpg hwy at 70mph and 14/15mpg city and that is in SoCal where we have the crappy blended gas. When I lived in the NW you could add 1 to 2 mpg to the hwy number, and city mileage about .5 more. Not only do we have poor performing gas here we are currently paying about $3.20 a gallon, up about 25 cents in the past three weeks.

#173 of 185 2007 Tahoe LS mileage by klmcleod

I have the 5.3 engine with 3.43 rear end.
Since May, I have driven 6600 miles, mostly Highway.
I keep detailed records of my mileage.
In Town 13mpg
Highway 22mpg at 65 mph
Highway 20mpg at 70 mph
Highway 19mpg at 75 mph
I use the cruise control consistently except when climbing hills. I actually get better mileage on hilly terrain. The engine utilizes the V4 option better on the downhill side of the terrain

I just bought a 2007 Suburban LT2 about two weeks ago. It is a K1500 and therefore has the 5.3L flex fuel engine with a 4-speed auto. I have filled it up three times now and have seen tank mileage of 17.7, 17.0 and 17.0 (all calculated manually, not relying on the trip computer). Second and third tanks had a greater portion of freeway driving, mostly at 70-75mph, plus commuting on country roads and highways. While I would like to see higher mpg, this is definitely consistent with my expectations and the EPA ratings (either new or old system). This is my fourth new car and the three prior cars I usually got mpg between the city and highway EPA ratings, typically closer to the highway rating.
 
I have watched the V4/V8 indicator and mine spends a fair bit of time in V4 mode, even at higher speeds. When? Well, here in Michigan the roads are gently sloping over slightly rolling hills, and even a slight downhill can put me in V4 mode. Of course, even a slight uphill puts me in V8 mode with instantaneous mpg of 16 or less. I think the AFM feature is useful.
 
While I would gladly accept higher mpg, I think my experience is quite reasonable given the size and power of the vehicle. There are many smaller SUVs that get the same or less mpg. I'm going to switch to synthetic oil at the first change and see if that makes any difference.

My 07 4x4 tahoe has nearly 15k miles, and your reported mileage is nearly exactly what I get. I live outside seattle, and my best mileage when I traveled on the freeway to and from work- (30 miles each way)the tahoe got 18-20 at best.
Now that I live in the suburbs and commute locally in town for most of my ride, I get 13-14 MAX. I dont mind, its a trade off for the great ride I get with the Tahoe. I just think the auto makers should be FORCED to report real world mileage, its far off of what was on the sticker and advertised by the salesman.
