FAQ - Filling up with Pure Plant Oil (PPO)

What is the difference between PPO and bio-diesel?

Bio-diesel is chemically altered (”refined”) vegetable oil. The process involves vegetable oil, methanol, a catalyst and heat. Glycerine is separated, a byproduct.

Which kinds of pure plant oils are suitable for powering (converted) diesel engines?

There are more than 2000 kinds of “oil fruits” (seeds, nuts, etc.), most of them usable as fuel sources. Oil yields vary quite a bit and therefore of course the oil price. Viscosity is also a variable that makes certain oils more suitable than others.

Rapeseed, sunflower seed and soy bean oil are the most affordable and widely available. It is important that the oil meets the so called DIN 51605 quality standard for cleanliness and viscosity (former Weihenstephan Standard).

Is there a quality standard for rapeseed oil?

Yes. The Weihenstephan-standard of 05/2000 that ELSBETT helped to establish which, however, was transformed to the DIN 51605 Standard. This is a list of criteria that an oil used to power a diesel engine should meet. The quality standard sheet is included in the booklet that comes with the ELSBETT conversion set.

Can I use used cooking (fryer) oil?

ELSBETT conversion systems are made to be used with oils that meet the DIN 51605 Standard and are not contaminated (for example with salt). Based on this it doesn’t matter if “virgin” oil or used oil is used. As long as attention is paid to the cleanliness and viscosity of the oil.

Will agriculture be able to meet the demands of future vegetable oil use?

Unlike petro-fuels, sustainable fuels are not going to run out. All over the country new producers, large and small, are popping up to meet demand. A positive side of this kind of fuel production is that it can happen regionally. Fuels don’t have to be shipped half way across the planet.

If demand increases very quickly, large amounts of unused farmland (subsidised and bought out) should be available to grow rapeseed for feed and fuel.

What would it cost to have my own plant oil filling station?

For only a little money one can have a storage tank (used) with a pump with filling nozzle for individual use. For larger consumers, businesses, etc. a large storage tank will be needed, this may cost a little more.

Are there safety regulations for pure plant oil?

It needs to be properly disposed of and can’t be washed down the drain or storm water drain. It is not flammable- it is considered a Class IIIB combustible.
