What do I have to do to convert my diesel equipment to run on BIODIESEL?
Nothing at all. BIO-DIESEL is a "pour-and-go" technology that can be used in any diesel engine application .

Blends of BIO-DIESEL in percentages greater than 20% have a few precautions that need to be considered.

Consider the following before using BIO-DIESEL blends above b20, up to b100.

Compatibility with Materials
--BIO-DIESEL is a solvent, and overtime will degrade natural rubber parts (i.e. hoses and seals) and soft or galvanized metals in a vehicles fuel delivery system. Generally, natural rubber parts only appear in vehicles manufactured before 1993. After 1993, most engine manufacturers began using synthetic rubber or compatible metal parts exclusively. If you are not sure of the composition of your equipment, check with your Original Equipment Manufacturer. The following materials are also adversely affected by higher blends of BIODIESEL: Nitrile, Polypropylene, Polyvinyl, Tygon, and Fluor silicon, brass, bronze, lead, tin, and zinc. These components can be replaced with Viton (the industry standard), Viton GFLT, Viton A401-C, Nylon 6/6 and Teflon.

Cleaning Effect
--Do you have an older diesel vehicle? Petroleum diesel forms sediments that stick to and accumulate in your fuel tank, forming layers of sludge over time. BIO-DIESEL will dissolve and clean these deposits from your fuel tank, fuel line, and engine. Although it is unlikely, material flushed through your fuel system may clog your fuel filter. You may need to change your fuel filter one or more times if this occurs. Fuel filter clogging will not be a problem at subsequent fill-ups.

Cold Flow
-- Like any diesel fuel, BIO-DIESEL can gel at low temperatures, however, the gel point for 100% BIO-DIESEL is higher than petroleum diesel. No anti-gel additives have been shown to be effective with b100. As a result, Zarco66 does not recommend the use of b100 (pure BIO-DIESEL) below 40 degrees F. During the part of the year when temperatures drop below 40F, Zarco66 recommends blending at least 80% petrol-diesel in the tank of the vehicle.

How do BIO-DIESEL’s emissions compare to petroleum diesel’s emissions?
BIO-DIESEL and BIO-DIESEL blends significantly reduce tailpipe emissions, especially carbon dioxide, carbon monoxide, sulfur dioxide, and particulates (black smoke). Using BIO-DIESEL decreases the cancer-causing risk of auto exhaust by 94%; B20 reduces this risk by 27%.

Will using BIO-DIESEL void my engine warranty?
According to the National Renewable Energy Laboratory, “Original Engine Manufacturers (OEM) provide a material and workmanship warranty on their products. Such warranties do not cover damage caused by external conditions, such as fuel. Thus, if an engine using BIO-DIESEL experiences a failure unrelated to the BIO--DIESEL use, it must be covered by the OEM’s warranty. Federal law prohibits the voiding of a warranty just because BIO-DIESEL was used—it has to be the cause of the failure. If an engine experiences a failure caused by BIO-DIESEL (or any other external condition, such as bad diesel fuel), it will not be covered by the OEM’s warranty.”

Zarco66 Earth Friendly Fuels sell only commercially produced BIODIESEL that meets ASTM D6751-03 specification.

What if I need to fuel my vehicle, but I can not get BIO-DIESEL?
Can I fuel my vehicle with petroleum diesel?
Can I switch back and forth between diesel and BIO-DIESEL?
Yes !!! BIO-DIESEL is the ultimate flexible fuel, so you can switch back and forth between BIO-DIESEL and petroleum diesel whenever necessary. Also, you can blend BIO-DIESEL with petroleum diesel in any percentage.

Is BIO-DIESEL safer to handle and store than petroleum diesel?
YES!! BIO-DIESEL is ten times less toxic than table salt and biodegrades faster than sugar. The EPA has tested BIO-DIESEL’s health effects extensively and has classified it as a non-toxic substance that poses absolutely no threat to human health. BIO-DIESEL does have a shelf life it should be used 6 months.
