for example this from the "Faq" on the site of the Optimus stoves:
http://www.optimus.se/products/[/url]or more explecid:
http://www.optimus.se/faq/WARNING!
Liquid fuels are extremely dangerous and should
be treated with extreme care. The fuels are
volatile and highly flammable. Many fuel kinds
(especially unleaded car gasoline) are health
hazardous. Inhaling unleaded car gasoline vapor
or getting car gasoline on your skin (e.g. hands)
may result in cancer. WE THEREFORE ADVISE
YOU NEVER TO USE CAR GASOLINE IN A
LIQUID FUEL STOVE.
Gasoline/petrol stoves
If your stove is a gasoline stove, use white
gasoline, Coleman Fuel, heptane and similar as
a first choice. In some countries 'unleaded
environmental gasoline' is available and can be
used as a second choice.
Unleaded environmental gasoline IS NOT the
same as unleaded car gasoline. Environmental
unleaded gasoline is a fuel designed for garden
machines (i.e. lawn mowers) with four-stroke
engines. It does not contain benzene and many of
the other health hazardous additives that are put
into car gasoline.
Unleaded car gasoline contains a lot of
additives that are needed for smoth engine
operation etc, but these additives are extremely
health hazardous and they are not burnt off
properly when used in a stove. Instead, they
escape as hazardous fuel vapour and exhaust
fumes. THEREFORE, NEVER USE CAR
GASOLINE OF ANY KIND FOR YOUR STOVE!

Multifuel stoves
1.Never use car gasoline and especially
not unleaded car gasoline. Car
gasoline is extremely volatile and
flammable, but worst of all it is
incredibly bad for your health.
You'll find similar deklarations on every english site of every stove-producer.
Only for the germans i haven't found those warning.
May be germans are in so much better health-conditions??
Oder ob man derartige Hinweise als ungünstig fürs's Geschäft einschätzt?
Wie auch immer, mit den Bleiersatzstoffen hat man gesundheitsmäßig den Teufel mit dem Beelzebub ausgetrieben.
Teufelchen Blei ist nämlich völig unverträglich mit Katalysator.
Und wer fragt schon öffentlich laut, was für Verbrennungsrückstände der Beelzebub hinterläßt..
Und wie oben erwänt: die Verbrennung im Kocher ist kaum vergleichbar mit den fortlaufenden Explosionen des gleichen Stoffes im Motor.
Für die paar Urlaubstage im Jahr gebe ich z.b. gerne den höheren Preis für Reinbenzin aus.
In Afrika etc, ist sicherlich Petroleum eine gute alternative, wenn man einen Kocher hat, der damit brennt.
