Also, in addition to diesel costs you also need to figure in how much oil
and fuel filter
changes are going to run you.
We replace our oil
and filters every 100 hours... about $50 a change... so if you are going 1800 miles you are talking 3.5 oil changes. We change the fuel
filters (we have three) every 200 hours, thats about $100 because two are proprietary. So an additional change lets say.
So, add in $400 to whatever cost you are talking about. Plus, you will probably need to change your engine
zinc at least once. An engine
used a lot uses a lot of engine zinc... so like $5 for that.
