MPG on 2500 Suburbans


Recommended Posts

Posted

Folks,

 

I was wondering if you could help me out. I would like to know what is the average MPG that a 2500 suburbans gets with the four options 5.7, 7.4, 6.0, and the 8.1 engines. I looking to upgrade from my 1995 suburban and would like to get some feed back from the guys that own these suburbans the pro and cons that would be great.

 

Thanks

My 2001 2500 Sub 8.1 4x4 3.73 4L8OE gets 11.75 around town, 13.75 on the highway @75 mph. Does not use a drop of fuel more than my '94 K1500 5.7 'Burban 4x4 3.73 4L6OE, and the power, well like I always say, "too much is just enough" :cheers: Build quality on the Mexican 'Burban is dismal. All components by the lowest bidder. Super el cheaso, interior, crappy vinyl used on the sides of the leather seats. The gas tank(s) is smaller which stinks, 42 gallons was SO COOL for towing on trips. I hate the sunroof, my head touches the headliner. Only one armrest on the captains chairs, lame. Center console blocks the center hump for usable storage. Overall it's smaller inside than the old body burbs. Third row footwell is smaller. AutoTrac system super duper sux, a quiche eating, sorry imitation of a real 4WD system. Transmission filter is very time consuming to change, as is the fuel filter and oil filter. On the plus side, the ride is quieter, smoother and less rattly, headlights are much better.

10 average 4 in heavy traffic 9 in mild traffic 14 wide open road at 65 maybe 12-13 at 80, towing 5000 lbs about 9-10 and 3000 lbs enclosed - 10-11, 8.1l 4x4, lots of power and lots of room :cheers:

12 around town, 13 - 14 highway, 10.5 towing 4000 lbs and full load. 8.1 with 3.73. Get about same mileage as my 99 GMC suburban 1500 but this thing pulls twice as well and I can't complain about the build quality. May be difference between 2001 and 2004.

 

Added Westers PCM and air intake, dyno at 306 rwhp and 409 rwtq. Not bad.

 

I'd buy it again in a heartbeat.

My '03 Burban 6.0L with 4.10 gets 14 Hiway, 12 Hiway towing and 12 daily driving over all of the hills around here. Build quality is better than I expected, I would probably get the bigger motor next time if I was driving it all of the time. My wife doesen't care. She loves it.

    • have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.
    • Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...
    • That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
    • Engine Wear and ISO 4406   1.) Cold Starts. 2.) High Particle Count. 3.) Low operating temperature viscosity and high low temperature cranking viscosity. 4.) Depleted AW, Friction and Acid packages.  5.) High engine load.    https://me.caltexlubricants.com/en_me/home/learning/from-chevron/heavy-duty-diesel-vehicles-and-equipment/The-Importance-of-Clean-Engine-Oil-and-Its-Impact-on-Equipment-and-Business-Performance.html   High particle counts have five sources. 1.) They are manufactured within the engine. Both wear debris and amalgamation of degradation products and combustion driven soot (worse in GDI). 2.) They are ingested via intake air. Ever hear the best oil filter is a good air filter? 3.) They are entrained in the fuel. 4.) This one is insidious. They are introduced in 'fresh oil'. 5.) They are introduced during the oil change.   ISO 4406 is the test that measures and quantifies the combine effects of all of the above particle related issues. You can mitigate your way into multiples of engine life by being attentive to them all.    https://www.hyprofiltration.com/blog/is-new-oil-clean   (from the link above)    [Quote] What Is the Recommended ISO 4406 Cleanliness Code for New Oil?   A good upper limit for new oil cleanliness is 16/14/11 (ISO 4406). Typical new oil usually has ISO codes of 19/17/15 or worse, which is far too dirty for sensitive components. This can be a major cause of degradation and premature failure.
