You save roughly 160 dollars in 10,000 miles on average with the diesel prices and your mpg I figure. 11.5mpg vs 16mpg avg. So in 100,000 you'll save 1600 dollars or so. I'm not bashing your diesel decision at all. Just running numbers on the savings. I'm glad your happy with your diesel. I thought about going diesel as well. A lot of factors go into the decision.
When I bought it diesel and regular were matched.
Again, look at my numbers.
3.50 a gallon for 87. 11.5 mpg. That's $.304 a mile.
3.50 a gallon for diesel. 16 mpg. That's $.218 per mile. So it's a savings of basically $.08 a mile. Or $24 per tank. I average 310 miles per fill up.
I've put 8000 miles on it in 6 months.
I'm currently seeing $425 for 87 and 5.25 for diesel.
87 is $.369 a mile
Diesel is $.328 per mile.
So I'm currently saving $12 a tank.
I have a much simpler platform. Less maintenance. Less baseline. And I paid at most 5k more than a comparable gas rig.
At .04 it'll take me 125k to surpass the gas rig.
But at .08 it's 60k and I'll do that in 3-4 years.
And even with 60k on the clock I still don't have 200k miles on my rig.
That said, I wanted diesel regardless.
I also wanted low miles and finding a local 80 under 200k was basically impossible when I bought mine.
This one was 25 miles away.
