Diesel's better comes to a close

Throughout the semester I have shown you all several benefits that diesel fuel and diesel vehicles have. I concluded with a few price comparisons that I would really like you to remember the next time your out car shopping. Diesel vehicles may cost a few more dollars in the beginning but you will save money over the life of the car.

I wish I could have given you my last comparison. It was going to be on the maintenance costs of a diesel and a gas vehicle of the same year and make. I didn't get a chance to do a blog post for this but I have been talking about it so here are the hard figures: 2005 gas Jetta 5 year total cost is $25,730.00; the 2005 TDI Jetta's 5 year total cost is $23,592.00; For a total savings of $2,138.00 over a five year period; Once again proving my point with dollars and cents diesel wins hands down.

I hope that I have opened some of your eyes to what diesel fuel and diesel vehicles have to offer. They are both better for us and the environment. They save us money and help keep our air clean. Are you thinking diesel yet? I know I am...

Diesel car base price verses Gas car base price

I have heard from several people that they think that diesel vehicles are too expensive. After conducting my research on the subject I agree that they are more expensive than a gas model. I have researched Kelly Blue Book's website to get you an honest comparison. These prices are posted for anyone to view and compair. I used KBB.com because it is a resource that anyone can use to research vehicle prices before they purchase there new vehicle.

The car I chose to compair was a brand new 2009 Volkswagen Jetta. I chose this vehicle because my brother wants to buy one in the near future and I hope that I killed two birds with one stone.

The 2009 Volkswagen Jetta 4-door SE Sedan's MSRP price is $21,670.00. Kbb.com also has a feature that showes what consumers are paying for the vehicle and that price is $21,453.00. The specifications for this car are as follows: gas mileage 20 mpg city / 29 mpg highway; engine size 5-Cyl, 2.5 Liter; Automatic Transmission, 6-Spd w/Overdrive & Triptonic; Front wheel drive; 4 door.

The 2009 Volkswagen Jetta 4-door TDI Sedan's MSRP price is $23,740.00. The price consumers are paying option price consumers are paying for the vehicle is $24,215.00. The specifications for this car are as follows: gas mileage 29 mpg city / 40 mpg highway; engine size 4-Cyl Turbo Diesel 2.0 Liter; Automatic Transmission, 6-Spd w/Overdrive & Tiptronic; Front wheel drive; 4 door.


Basing the price comparison of of the price consumers are paying you will pay $2,762.00 more for the diesel option. So if you purchase this vehicle you will pay more when you buy it. But over the course of a year or two depending on how much you drive by the time you hit 30,000 miles you would have saved over $1,400.00 in fuel savings and an additional $1,400.00 every 10,000 miles after that.

Basically what I'm trying to tell you is that before you turn away from a diesel because it costs a few grand more. Look at the fuel savings in the long run. Pay more now for the vehicle and drive forever for much cheaper than you could drive a gas vehicle.

Diesel Question and Answer

hello everyone, I have had several people respond to my blog and I have been a little flooded with questions. I am going to answer a few in this post and several others later. A few of your questions like how much maintenance is on a diesel versus a gas vehicle. I will tell you now that a diesel vehicle's maintenance costs are higher but I'm not sure how much higher. If you take care of a diesel you will be driving it for a long time regardless of how far you drive daily.

About my previous post concerning the sizes of the engine they were both eight cylinder engines. One was a a 6.0L and the other was a 6.4L. This just means that one engine was a little bit bigger than the other. The Ford diesel has a 7.3L that is much bigger than Chevy's 6.4L but surprisingly the Chevy has more stock horsepower. Its not the size of the engine but how its engineered.

To answer another question that I was given pertaining to when diesel engines and gas engines were invented. Ok you got me the gas engine was created first. Rudolf Diesel created the diesel engine in 1898. At least that is when he got it patented. I'm sure that he had this engine built around 1893 because he published a paper describing how his invention worked. We still are using Rudlolf Diesel's idea today in every diesel engine out there. His idea was that the diesel fuel and air combined withing the cylinder, then pressurized to ignite and power the engine rather than be mixed with air pressure and ignited by a spark plug. This invention changed the way that everyone looked at engines and resulted in several uses throughout the years. You can find a diesel engine in submarines, ships, trains, tractors, large trucks, cars and in electric generating plants.

I hope that I answered some of your questions and hope that I can get to all of them before the end of class. If I don't feel, free to research for yourself all it takes is a little time, the Internet and google. Check back soon for my comparison of maintenance costs of owning a diesel vehicle versus a gas vehicle.

Diesel truck verses Gas truck comparison

So I wanted to do a comparison for you on a gas truck vs. a diesel truck but these guys beat me too it. Of course the numbers are much smaller when talking about a truck because they are not used for commuting they are used for work. Towing, hauling and anything else you throw at them trucks will do it for you. The comparison below was taking off a website I found when I was working on my previous piece and I found the information very pleasing and wanted to share it.

Assuming the pump price of gas and diesel were the same, a diesel could save you $1500 or more in fuel costs per 100,000 miles of light duty driving and/or up to $2500 or more when doing a lot of towing or other high power demand driving, when compared to a gasoline powered truck with identical gearing. (These costs comparisons represent the estimated differences in fuel economy between a Duramax 6600 and a 6.0L fuel injected gasoline engine. When compared to a gasoline 8.1L, the diesel will save you even more.)Copyright © 1996-2008 by The Diesel Page



We all know that the price of diesel and the price of gas are not the same but this comparison still makes my point. A identical vehicle with a diesel option has better fuel economy that the gas option as well as the laundry list of other advantages. More power from the factory and a all around tougher truck.

Gas cost per mile verses Diesel cost per mile

So I think it is time to change all your minds about diesel and that huge number that you see by the price of diesel. I have called a local gas station that offered regular gas, diesel and biodiesel. The prices are as follows regular gas $1.79 per gallon, diesel $2.68 per gallon, and biodiesel $2.78 per gallon. These prices were provided by Woodfin Watchard at 4511 Pouncy Tract Road Richmond, VA.

Now were looking at almost a whole dollar more price per gallon gas vs. diesel and an additional 10 cents for the biodiesel. But when I crunched some numbers I was pleased to find that even though you pay more at the pump for diesel you save money in the long run. I did my comparison strictly off the price of fuel and did not add in maintenance costs.

I used a single car for my comparison and got the base miles per gallon from fueleconemy.gov. The car I chose to do my comparison on was a 2005 Volkswagen Jetta the gas model was a 2.0L 4 cylinder automatic and the diesel was a 1.9L 4 cylinder automatic. The gas model had a fuel economy of 28 MPG. The diesel model had a fuel economy of 38 MPG. Both of these MPG ratings are for stock vehicles rite off the showroom floor with no performance upgrades.

Here's my formula I took the cost of gas and divided it by the miles per gallon to get the price per mile we drive. Then I took that number and multiplied it by 10,000 miles which is what USAA insurance company considers a year of regular driving.

Number don't lie...

$1.79 / 28 MPG = $.1564 cents a mile multiplied by 10000 = $15,640.00 per year for the Gas
$2.68 / 38 MPG = $.1417 cents a mile multiplied by 10000 = $14,170.00 per year for the Diesel

Then you subtract the Gas year total by the Diesel year total to get the difference of $1,470.00 savings in the first 10,000 miles driven with the diesel. I don't know about you but that is a lot of money to me and numbers don't lie. Look at the numbers, use my equation and do some research for yourself. You may want to think diesel the next time you purchase a vehicle.

Biodiesel Engine conversion do you need it???

The answer to that question is NO! I have done extensive research and there are several costly products out there that add all these fancy gizmo's to your car to make it safe to run biodiesel (Melendez). As with any performance upgrade or anything that goes on with your vehicle check with your mechanic before you do anything. They know your vehicle. There is one thing that needs to be taken away from this post. Whether you run gasoline, diesel, or biodiesel you cannot fail to do your vehicles preventative maintenance. When you use biodiesel there is the risk that deposits can build up in your engines fuel system. But if you buy biodiesel that is manufactured from a company it was done correctly and has been cleared by the EPA for use in vehicles in the US.

If you are making your own biodiesel you have to make sure that you are making it correctly. Biodiesel is not just simply cleaned and filtered used oil. It is actually super clean oil and a few additives that combine to make the fuel ready for use in vehicles. When you purchase a biodiesel kit like the one I previewed in my previous post it comes with complete instructions. I do not have a biodiesel kit so cannot claim to know everything about biodiesel. Below are a few very helpful sites I found that can help you if you are ready to help the environment and go green.

If you still are interested in doing a biodiesel conversion or putting a biodiesel engine check out these the sites below I am just noting a few and you will have to do extensive research to see which of these is rite for your vehicle. I have searched for VW because our favorite teacher drives a TDI jetta. You can convert your TDI for $775.00 plus the cost of the installation.
