Why dont car manufacturers offer veg oil option?

Question

It's common knowledge that diesel engines can run on veg oil, so why don't the manufacturers offer this as an option? I think all it would take is a fuel pre-heater, different fuel injectors and a better fuel pump.

If a small percentage of new vehicles had this option it would help reduce emissions.

Answer 1

The vegetable oil is called bio-diesel and is not always a good idea for every application..
.
Some truckers think it's great and others report problems. Some get better mileage others report power loss on hills and still others say the fuel is too thick at temperatures below freezing.
Your right about what it takes, but is the cost worth it?

Until all the bugs get worked out, you may not see it as an option until 2011 or later.

Answer 2

Car manufacturers have to make their cars meet European emssions regulations.
The current (and future) regulations are not easy to meet - and are best met by using very high pressure injection systems with very small nozzle diameters. Vegetable oil clogs up the injectors and the high-pressure pumps.

Older diesel engines (designed to meet much less stringent emissions regulations) with larger nozzle diameters, and low-pressure indirect injection systems can easily be converted to run on vegetable oil, but newer engines cannot.

The availability of vegetable oil for fuel is currently limited, therefore the manufacturers have to assume that their cars will be run on readily available fuel, and designed to meet the emissions regulations while running on readily available fuel.

It will take changes in European emissions regulations before manufacturers are able to offer this option.

Answer 3

first there are two states where diesels cannot be sold, period because of air quality laws. the new ultra low sulfer diesel that came out in the past 6 months is supposed to change that and more manufacturers are going to make diesel cars next year. Toyata is even talking about switching the prius over to diesel to make it even more effecient. just switching to diesel alone will save you 30% in fuel costs, and that's just using the diesel that's out there at the gas stations. As far as vegetable oil, if dumpster diving behind the local Popeyes chicken evertime you need a fill -up is your thing, go for it, I'll pass.

Answer 4

This is because it is not yet an option that promises to yield a significant enough profit margin, meaning that there is not enough demand for this option. It probably will not catch on because of the preparation that is required for making the used vegetable oil ready to use for fuel, even though this process is relatively simple.

Answer 5

to be on the careful area i could be tempted to run on a mix until you experience helpful sufficient to alter over thoroughly then if any harm takes place and that's a prior automobile not plenty misplaced yet once you have a greater present day automobile persist with the right diesal .

Answer 6

because vegetable oil can be cheaply and easily bought and converted to use. the government would lose out on billions in tax's

oh and the place would smell like a takeaway. lol

Answer 7

it does not require any of what you said you can run most diesel cars directly on used cooking oil with no modifications

Answer 8

the government don't get tax from it so they don't want you to know it is possible.
