So i did some math on this because I find the idea intriguing. It would be cool if you could justify a diesel conversion based on fuel savings but by math that is still a ways away.
assume 12.5 mpg for gas and 25 mpg diesel (imp.)
assume C$15,000 for conversion costs all in (educated guess)
assume maintenance costs are the same
assume diesel/gas price parity @ $1.00/litre or $4.50/gallon (imp)
3,333 gallons = C$15,000
= 84,000 miles travelled in the diesel to break even on a straight line valuation
-if you assume diesel stays 5% pricier than gas and amortize the up front conversion cost at 3% per annum assuming 12,000 miles per year (7 years) then you are up over 100,000 miles to break even.
-if gas prices go to $1.20/litre = 70,000 miles to break even on a straight line basis, or around 90,000 miles adjusted
-if gas goes to $1.50 litre = 56,000 miles on a straight line basis or about 70,000 miles adjusted.
-if this is not your daily driver it will take a long time to break even.
-once you had paid off the initial investment you'd have a great vehicle but you would also have put a lot more mileage on your already used diesel powerplant (and tranny)
this all ignores how cool it would be to have a diesel and maybe even a 5 speed, but it also ignores the parts costs for that diesel. I think a conversion makes sense if you have an 80 with a dead motor or you can buy one very cheap, but otherwise you are better off driving that gasser until it dies (which will be a long time
