Does converting a diesel engine to burn both fuel and vegetable oil significantly reduce the emissions?

Question

I just bought a great vehicle that has a 4 cylinder diesel engine that gets great fuel economy but I would like to do more. I have already had it into the shop to help me reduce the occasional smoking that it does but I have seen a few people who have converted the vehicle to burn BOTH diesel and veggie oil. Dose anyone know if this alternative fuel will actually reduce my individual emissions? Are there any recourses out there to do the conversion myself? Thanx!!

Answer 1

Not likely.  Diesel produces more waste than a regular gasoline engine.  In fact, you also need 25% more oil to produce diesel than you would need to produce gasoline.  Although many companies hype diesel engines, I truly believe they are just as wasteful if not more so than a regular gasoline engine.  The best thing to do would be to buy a vehicle which gets high mpg (Toyota corolla etc...).  A hybrid vehicle is good, but unless you are doing a lot of highway driving it is not necessarily worth what you pay because it will get the same mpg city driving as a regular gasoline car.  Flex-fuel vehicles are probably the best options right now.  There are also hydrogen vehicles which are equally as good.  Flex-fuel has been around since the 1970s in Brazil, how come the U.S. hasn't incorporated them into our fuel industry?  Because the oil companies are in with the government that's why.

Answer 2

It may not reduce your individual emissions but that technology is for re-using filtered oil thats been used at a restaurant for their food. so instead of it getting shipped off to some waste landfill it can be used a second time and not polute the ground.  Don't need any more oil to produce diesel than gasoline... Diesel fuel is processed less than gasoline.
