Bay City MI to Calhoun GA on one tank of diesel

[Fireman591]

Dang I love this Suburban. We had a head wind all the wat down and set the cruise in the 72-74 range most of this leg. One of these trips i will get a tail wind and average well into the 30's.

Over 765 miles? Awesome! How does she ride at 39 psi?

Here’s a trip from Medford, OR to Paso Robles, CA we did back in February. The only reason we stopped a couple of times was potty breaks for the kids!

Best road trip car ever. Fireman is this a replacement Suburban for you from a buyback?

We did Indianapolis IN to Valdosta GA on one tank about a year ago, got scared and stopped 30 miles before Valdosta for fuel because the range indicator went from 0 miles to LO.
Well over 700 miles including Atlanta traffic. Not doing that again tho..!

Not bad. When I left MI they were all at 35 psi.

I hear ya. We normally fill up in Cleveland TN or Ringold GA but I had enough range to make it to the Buc EEs in Calhoun GA. The range was at 55 miles but when I left I75 and turned the range went to " LOW"

No we still have our lemon law Tahoe. We did a cash and keep deal with a 6 year 75k 0 deductible GMPP warranty. It is a good daily driver for us and we don't venture to far from home with it since those 5.3 and 6.2 engines are ticking time bombs with push rod bending and lifter issues. We will get rid of it just before the warranty expires.

Don't like that dash setup but sure impressed with those numbers. Don't think my skinny butt would handle a non-stop drive like that with our hard seats though. Hard to beat a diesel on the road!

Gotcha. I recalled you had some sort of saga...

After 4 trips in for the camera system, two sides of bad lifters, and the transmission failing (67 days in for service in 9 mo. - musta been built in a Friday).....I got them to rebuy/replace, and went with the diesel. Love it, engine feels just....better.

We stopped for breakfast and lunch along with many rest stops. We left at 3am so 12.75 hours later we arrived at the Buc EEs in Calhoun Georgia.

How much fuel does it hold? Must be more than my Silverado.
My dash says I get mid to high 20s for mpg (short trips), best has been 36.4mpg (from the dash, not calculated)

[FatBob]

Thanks for the reply, IIRC my Silverado holds 24 gallons.

yeah i think that's the Tahoe capacity too.

Yes my Tahoe has 4 gallons less than my Suburban.24 vs 28

Just did a similar mileage run...
Sedalia, MO to Clarkston MI, one rest stop, filled when I left and low fuel warning light came on one mile from my exit so 3 miles from home.

My 2013 Yukon XL is getting up there in mileage and age. Thinking of a new one with diesel engine. Do you owners find that the increased mileage offsets the higher price per gallon for diesel? Also how does it tow. I currently toe a boat the is about 7000 pounds including trailer etc. My 5.3 with trailer package has no problem.

Thanks

Diesel fuel has come down since I bought my Silverado 11 months ago. I have paid as much as $1.80 more the 87 octane regular, to as little $0.20 more.
I had a 2011 Silverado w/6.2L engine that I always bought premium fuel for, which now costs more than diesel.
The higher fuel price would not be my main concern.

I came across this recently, for some odd reason:

Good analysis of the bottom line. It is better, even with increased fuel costs, but does take some miles to make up for the up front costs. I don't tow, but from what I have heard, the 3.0 diesel is great at it. The low end torque makes this engine so much more fun to drive than the 5.3 (I had that first, for a year, then got the Duramax).
