Let’s say two cars are being considered.

Both are exactly alike, except one is gasoline powered and the other is Diesel powered.

Both have a 10 gallon tank.

Gasoline is $4.00 a gallon.

Diesel is $5.00 a gallon.

The gasoline model gets 40 mpg.

The Diesel model gets 50 mpg.

Gasoline miles per tank = 400 miles.

Diesel miles per tank = 500 miles.

Gasoline trip costs = $40.00

Diesel trip costs = $50.00

You go 100 miles farther for $10.00 in the Diesel.

That $10.00 would have bought 2.5 gallons of gasoline, that would have carried you 100 miles...........

So, as long as the DIFFERENCE in cost per gallon between DIESEL and GASOLINE is less than about $1 per, then you are ahead.
But remember the initial cost of the diesel car is higher than the gasoline car, but it will last much longer on the road because of the way it’s made........

Once the demand for diesel fuel increases, the price will come down. Diesal is a byproduct and not much is produced in relation to gasoline.

And has a dramatically higher resale value.

Replacement Cost is still the largest per-mile expense
on small and mid-size autos. Competently made diesels
have an advantage here, because you either get more
back on resale, or get many more years to drive it
into the ground.

The engine will last longer. The engine isn't what usually wears out first on most cars, and VWs often have other reliability problems.

I wouldn't count on the longer engine life adding much actual value to the car.
