my 2 cents
OK here is my 2 cents.
I was in the same situation you are in about a year ago. When the Hemi's came out I had to have one. I bought an 03 Quad cab, SWB, Laramie, in slate gray, 4x4. Basically it was loaded and the first new truck I have ever bought. After about a year of driving it and putting about 12000 miles on it, I started to get tired of NEVER seeing the AVG MPG under normal driving go above 9-10 MPG in town and 12-13 on the highway. I took very good care of the truck inside and out and spared no expense on maintenance. I even changed the Mobil 1 I was running in it about every 2500 to 2800 miles at about 60. 00 a pop. I got tired of seeing gas prices going up and thought about buying a diesel. I had never owned one, nor had my family while I was growing up. I had very limited knowledge at the time. Needless to say I spent many a sleepless nights doing research.
The things I came to understand are this.
Oil Changes = Hemi = 60. 00 every 3000 miles, Diesel = 55. 00 every 7200 miles. Cost difference = Hemi 120. 00 for 6000 miles, and the diesel still has 1200 miles to go on the 55. 00 oil change. And that is having the dealer do it. Savings over 14000 miles gas v. diesel = 240. 00 to 55. 00. I am not counting the initial oil put in by the dealer. Also at 14000 miles the Gas is 1000 miles away from another 60. 00 oil change and the Diesel is 400 miles. On average the gas is costing you . 02 cents per mile for oil. The diesel is costing . 00764 cents per mile.
100,000 miles
Gas = 2000. 00 in just oil
Diesel = 764. 00 (1236. 00 in savings)
Here is where I got hooked.
Gas v. Diesel Fuel
Shure diesel is more than gas. WHO CARES!!!!! I was getting 225 miles out of a tank of gas in my HEMI. It might have cost me 47. 00 to fill it up at 1. 79 a gallon and 26 gal. When the fuel light comes on in the Diesel it costs me 57. 00 to fill her up at 1. 90 a gallon which equals 30 gallons of fuel. This is only a 10. 00 difference at the pump. The real difference is how far can you go?
On average gas = 225 miles at a cost of 47. 00 = . 2089 cents a mile in gas.
On average Diesel = 500 miles at a cost of 57. 00 = . 114 cents a mile.
I have put 16000 miles on my Diesel since I bought it.
16000 miles diesel = 1824. 00 in Diesel
What it would have cost me in the Hemi = 3342. 40
Savings 1518. 40 divided by 12 months = 126. 53 dollars
Add that to the oil savings
Gas 16000 miles at . 02 = 320. 00 divided by 12 = 26. 67
Diesel at . 00764 = 122. 24 divided by 12 = 10. 19
Savings a month = 16. 48 saved a month
126. 53 + 16. 48 = 143. 01 a month in savings :-laf
Now I do realize that prices on fuel are constantly changing and my numbers might not be exact scientific calculations, but I know I am close.
If I remember correctly the Payments on my Hemi were about 550. 00 a month. The payments on my Diesel are about 720. 00. Difference = 170. 00 more for the Diesel. BUT you take the 143. 01 a month I am saving in Fuel and oil alone and it is only a 26. 99 dollar difference. I can take my lunch to work 3-4 days a month for 26. 99.
One other small benefit is RESALE VALUE and HOW LONG WILL IT LAST!!!!!!!!!!!!!!!!!!!!!
I figure it would take 2-3 gassers to last as long as my 1 diesel. Was it worth the switch? DEFINATELY!!!! I don’t think I will EVER own another gasser truck of my own free will. I have even thought about buying the wife a diesel VW Jetta. It is only a 100. 00 cost to upgrade the motor.
Just my 2 cents. (small voice inside that says GET THE DIESEL!!!!)
