I have another fill-up data point to add to the Titan XXL measurement matrix: Before going out to Foxboro last weekend, I tanked up with approximately 55-60 miles on the DTE:
= I was able to fit 33.5 gallons @ $2.899/gal before the pump shut off at $97.00 because the tank was full
= Previous fill-ups (34.5 gallons) were definitely hitting the $100 pump max/price auto-shutoff (or pretty **** close to it)
= 55-60 DTE miles represents 2.5-3.0 gallons of fuel (based on 22-25 MPG)?
= I am guessing that the 5.5 gallons (40 - 34.5) left in the tank (at DTE of 0 miles) will yield ~100 miles of driving on reserve once you hit "E" but I don't have the balls to test my math!
