FREQUENTLY ASKED QUESTIONS

Can bio-diesel be used in any diesel vehicle?
YES, biodiesel is produced through a chemical process called transesterification, which converts oils and fats of natural origin into fatty acid methyl esters (FAME). Combustion of vegetable oil without conversion to biodiesel will lead to soot accumulation and deposits that may lead to power loss and engine failure.

What is in biodiesel?
Biodiesel is made through a chemical reaction between natural oils and methanol, followed by purification. Biodiesel can be made from nearly any naturally occurring vegetable oil or fat.

How much Biodiesel is made from 1 gallon of used vegetable oil?
From our system, it is approximately a 1-1 ratio. Generally you will see 1 gallon of vegetable oil makes 1 gallon of biodiesel (1 : 1). Lower quality oil (more used or aged) can reduce that ratio a little, 1 : .95 for example.

What chemicals are required to make biodiesel and where do you get them?
Two common chemicals are used to cause and complete the chemical conversion process. Lye and Methanol.  Lye can be purchased from most hardware stores and methanol from fuel distributors or racing/speed shops. If needed, No-Bull can assist you in finding a local dealer in your area once you purchase your system.

Is used vegetable oil hard to get?
No, all restaurants have to dispose of their used oil, and many pay to have their waste oil picked up by a company.  If given the option to have the oil taken away for free they normally go for the idea.
 
Do I need to do any modifications to my diesel vehicle to use biodiesel?
If your car was made after 1993, the answer is no. If your car was made prior to 1993, the rubber fuel lines will probably have to be replaced. One of the major advantages of using biodiesel is the fact that it can be used in existing diesel engines without negative impacts to operating performance. Biodiesel is the only alternative fuel for heavyweight vehicles that does not require any special injection or storage modifications.

Can I run biodiesel in my gasoline engine?
No, biodiesel can only run in conventional compression-ignition (diesel) engines!

Can I go back and forth between petroleum diesel and biodiesel?
Yes, you can use both. Biodiesel and diesel fuel can be used interchangeably or blended.

Will I need to change my fuel filters more often when using biodiesel?
Biodiesel is a solvent. It will clear many diesel deposits that have accumulated in your fuel tank. This may cause initial fuel filter clogging, but continued use of biodiesel will not cause an increased frequency of filter changes.

How does the fuel efficiency of biodiesel compare with petrodiesel?
Vehicles running on biodiesel get virtually the same MPG rating as vehicles running on petrodiesel.

Is biodiesel good for my engine?
Yes, biodiesel can actually extend the life of your engine. Biodiesel has superior lubricating properties that reduce the wear of vital engine parts.

How do the emissions of biodiesel and petrodiesel differ?
Using biodiesel instead of petrodiesel will significantly reduce unburned hydrocarbons, carbon monoxide, and particulate matter from tail pipe emissions. It will also virtually eliminate sulfur oxides and sulfates which are major contributors to acid rain. Nitrogen oxide emissions may slightly increase, but can be remedied with newer low-emission diesel engines.

Does biodiesel contain diesel fuel?
Pure biodiesel, B100 (100% biodiesel) does not contain petrodiesel. Biodiesel can be blended with petrodiesel and is frequently sold as B20 (20% biodiesel, 80% petrodiesel blend) or B5 (5% biodiesel, 95% petrodiesel blend).
