It is not sure a pure ignition improver as IPN, mostly as cleaner for diesel injector/pump equipment and some extra to example reduce soot etc etc.

Status: offline 		I have used and made my own Diesel fuel for a long time.
I used one part of each - Ether Anaesthetic, Kerosene Oil and any common motor oil. (5W30 etc)
A little more Ether makes starting easier and is recommended but I never had any problems with the one part each ratios. In case you need to store the fuel for a long time, add a little more Ether. Amyl Nitrate is not necessary but may be used. Avoid medicinal Castor oil as it will break up under compression and cause excess engine wear.
Ether is available from stores that supply Laboratories and Hospitals. Use it in a ventilated area only.

With the greatest respect sajjad, most engine manufactures (PAW, ST, Olly T, etc etc) say do not use common motor oil as it is not designed to be burnt, as happens in a 2 stroke motor. Amy Nitrate or IPN etc is required for any high performance motor to make it run smooth and produce the power the makers designed into it.

Re Castor oil, I believe medicinal castor is fine, tho I now use motor racing Castor, for over 20 years I used medicinal Castor in my PAW's (plain bearing and BR's) ST's etc, and have never had to replace any moving parts in any of them.

Here in the UK Anaesthetic Ether would be very expensive, we use "solvent grade" Ether, just fine

The following is snipped from the PAW site at =

I agree though that on a large, mild, converted glow motor, (as this post started with !!) turning a big prop, your brew will work ok.

Where in our world are you my friend ?

Hydrogen peroxide is very easy to get.

Status: offline 		Don't even think about Hydeogen Peroxide. First off, the readily available stuff is only 3 to 5% Hyderogen peroxide in water. If you wer succesful in obtaining high strength peroxide, adding it to the fuel mix would most likely initiate a violent fire. Pure Hydrogen peroxide is very dangerous stuff. I saw a spill of about 100 gallons of the peroxide on an asphalt pad and the asphalt caught on fire.

Status: online 		Just getting interested in 2 stroke compression engines (2SCE). I would like to know why acetone could not be substituted for the ether in these home brew fuels. The Air/Fuel mixture seems close both in 9.5-10.5:1 range; acetone has lower BTU/lb (12500 vs 15000); Flash and Boiling points are they a consideration?

Educate me.
Thanks

We need ether to lower ignition temperature, therefore it ignite easier than pure kerosene in compression temperature. Ether has ignition temperature at 188 C degree. Ether helping to ignite kerosene who has higher BTU than Ether.

Acetone has ignition tempetature at 465 C degree, can not ignite in the engine with compression temperature. Also unuseful...

Yes, these start gas spray can has liquid Diethyl ether. I has tried "Turtle Wax" start gas can and works well.

Status: offline 		John Deere starting fluid is in a spray can and claims to be 80% ether. I take the can outside after shaking it up and hold it upside down to spray out all the propelant. Then put the can in a freezer for a couple hours. Take outside and with a hammer and a nail make two holes in oposite corners of the top of the can. One hole to pour out the liquid and the other a breather hole. Pour into a container and you should get about 8 ounces. Remember only 80% oth the 8 ounces is ether, count the remaining 20% as kerosene, at least I do. I like to mix any fuel up in the winter outside on a cold day. Make sure no one is smoking nearby. Go on Google to find a John Deer dealer near you and call to see if the fluid is in stock.
