I sure hope you Diesel Brothers have extra filters, oil, and fuel on standby. My friends are having problems finding filters and oil. Moreover, I keep hearing - 'here or there' - there's shortages of parts, oil, & filters. If these parts become unavailable, do people think those items won't go to transport over citizens? What happens when there's barely enough diesel to deliver food?
Diesel is 5.15 and gas is 3.55, so it doesn't take a mathematician to see they equal out with mileage. However, after you add DEF and the extra maintenance - diesel is currently more expensive to run. Since we're bringing up resale, we should bring up the added insurance premium to run diesel engines. My insurance would have been $17 more a month to have a Cummings.
JIC, gas is 68.9% of the price for 1 gallon of diesel, in GA. If a diesel only gets 30% more milage, than its a wash, until you add up the other diesel costs. I only see 20-25% better rate, but that's math without feelings. Using examples here, I see 7.5-9 gas vs 10-12 diesel towing, using worst-to-worst or best-to-best those are under 30%. Without towing the differences are still the same with consumption (14-17 gas 19-22 diesel).
I wanted a diesel badly, I've never owned one, and will still get one if parts, fuel, and service come back to pre-"pandemic." My prediction is, 3/4 & 1-TON GASSERS will be more coveted and demand higher $ soon, because of these issues.
