If we want to compare to a 2019 F150 with max efficiency rating of 30 mpg, assuming a cost per gallon of 2.50 and assuming 2 full synthetic oil changes at $90 each:
17500m / 30mpg = 583.3g ... 583.3g x $2.50 = $1458 (rounded down) ... $1458 + (2 x $90) = $1638 ... $1638-$425(cost for the Leaf) = $1213 saved in one year.
If I lost 5 miles of range on my battery every 2 years - over 10 years, I'd be left with 55miles of range (which would still be enough to complete my commute mind you). In those same 10 years, compared to my Prius, I would have saved a minimum of $6130... Remember I only spent $11K on this car to begin with. That savings is assuming that gas will remain at $2.50/gallon, and my electricity rates stay at 10.31 cents. If I wanted to buy a replacement battery at that point - which at today's cost is roughly $7500 USD for a 40kwh pack - it would nearly have paid for itself.
On top of that I am grandfathered in with my utility for 100% net metering on my solar panels, and after two years, they have proven to provide our home with nearly 100% energy needs year round (when you account for the 100% net metering). For one month of commuting - 20 days at a conservative estimate of 12kwh charged for the vehicle a day (and absolutely no other energy spent on the home)... I use 240 kwh... my energy bill is ~$8/month, so if all I used energy for was the car, I'd still only be paying $0.0334 per kwh.... So, in reality, it's much cheaper than what I described above.
