Just paid $2.559 for diesel in San Antonio, TX. Regular was $2.799 at the same station. Loving the diesel Tahoe.
does this price include the price of DEF ? the cost per mile is way higher

not everyone can buy from a DEF pump though
Don't be a hater! I buy my DEF from a Pump. However, I can buy 2.5 gallons for $11.99 in several locations around town. That will last me at least 3000 - 3500 miles. Diesel is way more economical when the diesel vs gas prices are where they "should" be. Towing is a different story on the DEF, but the MPG spread gets alot better in favor of the diesel when towing too... This is my first diesel after 5 gas powered GMC Trucks and Yukons and I am a convert.

I have 21k on my Suburban, at most I have used 4 boxes from Costco (~$15 each), plus two pump fills (~$12 each). That's $84. Round up to $100, that's 0.005c/mile.

Pretending I remembered incorrectly, let's say 8 boxes, $150 total, that's 0.007c/mile.

My lifetime MPG is ~24+. So for every gallon of diesel, I have spent maximum 0.17c extra. More likely less than 0.12c/gal extra.

I guess "way higher" is subject to personal perspective, but 0.12c/gal is not terribly significant to me.

Edit: I should add that at 21k miles, I have a full tank of DEF, so in reality it probably took less than $70 in DEF to get me to 21k: 0.08/gal.

Don't forget the penny per mile cost for the wet oil pump belt "service job" required at 150,000 miles on our Duromax SUV's that our gasser SUV's don't have :thumbsup:

** GM says it's a 7 hour job plus parts and shop supplies, so I'd guess +/- $1500 at a GM dealer.
