FAQ - Frequently Asked Questions

Can my vehicle be converted with the kit?
The ATG Vegetable Oil-Kit is suitable for diesel engines with in-line or distributor pumps from Bosch (except for type VP44), Diesel-Kiki, Nippon-Denso or Zexel. The conversion of diesel engines with Bosch VP44-injection pump and high-pressure fuel injection like unit-injectors pumps is only possible through skilled ATG Conversion Partners.

The size of the additional fuel tank depends on the vehicle type and the available space. As a rule the main tank is filled with vegetable oil and the secondary tank with diesel. It is also possible to leave the original tank as the diesel tank and to fill the additional tank with vegetable oil.

If you have any further questions, please do not hesitate to contact us.

Where can I order the conversion kit?
The conversion kit can be ordered from 4x4 outdoor tuning.

Where can I have my vehicle converted?

The conversion can be performed by 4x4 outdoor tuning or by any reputable garage/mechanic. The installation requires an understanding of diesel engines and should be installed by a skilled specialist (e.g. auto mechanic)! Nevertheless a DIY (do-it-yourself) conversion is also possible. For your own protection, please check with the appropriate authorities in your country if there are specific provisions concerning changes on the vehicle.

Is the conversion permanent?

No, it can be returned to its original state, e.g. when selling the vehicle. The components can simply be removed within short time. All of the components can be reused.

Are there any long-term studies related to operating diesel vehicles with vegetable oil?

Tests and studies have shown that heated vegetable oil has nearly the same properties as diesel fuel and burns just as effectively in most engines. On the strength of past experience almost every diesel engine can be driven with straight vegetable oil after a conversion, provided that the motor is maintained and in good repair (compression, fuel injectors, glow plugs, ...).

Can the new generation of diesel engines (unit-injectors pumps, common-rail-technology) be operated with vegetable oil?

In principle, it is possible to operate these engines on vegetable oil. The conversion of diesel engines with high-pressure fuel injection like unit-injectors pumps is only possible through skilled ATG Conversion Partners.

How do injection pumps react operating on vegetable oil?

Injection pumps from Bosch, Diesel-Kiki, Nippon-Denso or Zexel have shown the best results when operating on vegetable oil. Injection pumps from Delphi, Lucas, CAV, Stanadyne and Roto-Diesel are only partially suitable.

Can I operate my vehicle on vegetable oil during the winter months or at freezing temperatures?

Pure, untreated vegetable oil is getting viscous and sticky at freezing temperatures. Depending on the type and the properties of the vegetable oil, this condition will happen sooner or later. In order to prevent the vegetable oil from gelling in the tank or fuel lines, a mixture of vegetable oil and normal diesel fuel is recommended during the winter months.

How does vegetable oil effect the engine’s properties?
Usually, the engine’s properties (operation, performance, consumption, ...) remain unchanged.

Does operating an engine on vegetable oil effect its regularly scheduled maintenance?
As a rule, the maintenance intervals remain unchanged and should be adhered to as specified by the manufacturer.

Can parking heaters operate with vegetable oil?

Parking heaters are not suitable for operating with vegetable oil. If your vehicle has a parking heater, you should consult with the manufacturer beforehand to see whether an additional conversion is possible. With the two-tank system, parking heaters can still operate on diesel fuel.

Can normal diesel fuel be mixed with vegetable oil?
Yes, normal diesel fuel can be filled in the vegetable oil tank at any ratio.

How expensive is vegetable oil and where can I purchase it?

Vegetable oil is a foodstuff and usually not subject to a mineral oil tax. Vegetable oil is a natural product and an inexpensive alternative to conventional diesel fuel. Smaller quantities of vegetable oil can be purchased in any supermarket or wholesale store. In the long term, it is more preferable to purchase vegetable oil from suppliers (e.g. oil mills) in the region. Recycled or used vegetable oil (WVO waste vegetable oil) can also be used provided that it has been cleaned and filtered (min. 1 µm).

Is it generally permitted to drive using vegetable oil?

For your own protection, please check with the appropriate authorities in your country if there are specific provisions prohibiting the use of vegetable oil. This is also to be done for any changes on the vehicle to be converted.

What is the difference between vegetable oil and biodiesel?

Vegetable Oil
All biofuels (e.g. vegetable oils) are CO2-neutral and free of sulfur and pollutants in their pure, untreated state.

Additional advantages of vegetable oil

- inexpensive
- nontoxic
- biodegradable
- water reactivity 0
- flash point approx. 300°C (reduces the risk of fire or accident)
- requires less energy to produce
- locally produced
- protection of limited fossil fuels

Biodiesel = Rapsmethylester = RME
Biodiesel is chemically produced and substantially more expensive than plain vegetable oil. A problem is the durability of plastic and rubber components (sealings), which come into contact with biodiesel. If biodiesel is used in a system that has not been adapted, leakages on the fuel system and defects on injection pumps are the most frequently troubles. When using pure, untreated vegetable oil, these problems will not occur.
