What about normal paraffin?
"Petroleum-derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes).[25] The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28."
paraffin is much cheaper over here than diesel.
Can I run paraffin and add 2SO as a lubricant @ say 200ml per 100L?
Good call re paraffin.... I'm going to look into it! First off, where do you get it nowadays??!! The other option I'd that ethanol based fuel that's now available at some Shell outlets....
never, the td5s not rated for it because of the injector pressures.Quote:

Paraffin doesn't have the same lubricating properties as diesel, and will do serious damage to the engine with long term use. Also, unless I'm very much mistaken, the reason that paraffin is so much cheaper in ZA than diesel is that diesel is taxed, paraffin isn't, and running a car on paraffin is illegal, same as Ireland and the UK, and that customs and excise dip diesel tanks randomly and apply very hefty fines of you're caught.Quote:

You could talk to the local airfield: high grade paraffin is used in most turbo-fans as jet fuel?
"Turbine engines can operate with a wide range of fuels, and jet-aircraft engines typically use fuels with higher flash points, which are less flammable and therefore safer to transport and handle. The first jet fuels were based on kerosene or a gasoline-kerosene mix, and most jet fuels are still kerosene-based. Both British and American standards for jet fuels were first established at the end of World War II. British standards derived from standards for kerosine use for lamps—known as paraffin in the UK—whereas American standards derived from aviation gasoline practices."
The airports, AFAIK, need to drain certain amount from the storage tanks, as well from the planes a pre-flight check for water contamination and they probably need to dispose of this fuel in a proper manner.........:)
- lubricity: yes, fair point, hence my query regarding 2SOQuote:

IMHO if I want to run my car on hi grade jack daniels I should be allowed to......
WVO/SVO blended with diesel is too hard for our ATO to work out how you should pay your excise on if you're a private user and not selling it on.
after 3 years of documenting what I was doing and keeping the log books but getting essentially told "too hard to work out mate, so long as you're not selling it or using it to make a profit don't worry about it" I gave up on bothering with it.
I'm sure that there are additives that can compensate for the lack of librication in paraffin, sure.Quote:

Of course, that x number of litres can't be checked, so... :)Quote:

Well I was born in Ireland, not Australia, and Customs and Excise do indeed check car fuel tanks to make sure that they aren't running on marked diesel or paraffin. They don't even have to pull you over on the road - quite often they will run around a supermarket car park on a Saturday and dip all the diesel cars while the owners are in shopping. Or cattle markets where there's a good chance of farmers running their cars on ag diesel. It's not hard to enforce at all.Quote:

Government roads, government rules.... so no, you can't just "do what you want".Quote:

Mike, my memory of the legislation in the UK was effectively anything that could be chucked in the tank of a vehicle to power it could be considered a fuel, and was therefore expected to incur fuel duties at the appropriate rate. I remember stories on the news of people being busted for dodging the tax, for home brew biodiesel, being pulled over by a copper if their car smelt of fish and chips.....Quote:
