How to make your own octane booster.

Tired of paying $3-$4 or more for a can of octane booster to get the crap they call gas spewing from the local station's nozzles to work in your car? Make a suitable substitute from the hardware/autoparts store.

Instructions

Difficulty: Easy

Things You’ll Need:

• An empty quart container
• An empty half pint container(for ease of measuring)
• A small funnel
• 1 gallon acetone
• 1 gallon xylene
• 1 quart good quality synthetic 2-cycle oil.
• (All the above ingredients I found at a local Home Depot)

1. Obtain your supplies from a hardware store. The Synthetic 2-cycle oil may have to be obtained at an auto parts store, but I have found it in the lawn & garden section of most hardware stores. The acetone, and xylene are both paint thinners, so they are in the paint section. Xylene is a component already added to gasoline for stability, and acetone cleans build up and breaks down the covalent bonds in petrol. The 2-cycle oil helps upper end lubrication of the engine, and stabilized burn a little also.
2. The mix ratio is 2:1:1 acetone/xylene/oil, respectively. For ease of mixing use the half pint container, plastic, cleaned out of original contents of course, and fill it with acetone pour with funnel into the quart container(oil bottles are perfect), do this twice. Now fill it once with xylene, pour into quart, and again with the 2-cycle synthetic oil. 1/2pint x 4 = Quart of homemade octane booster.
3. Add 3oz. of your booster to 10 gallons of gas.

Tips & Warnings

• A cheaper variant is to lower the amount of 2-cycle oil by half.
• I drive an old carbureted Jeep, and have noticed that it doesn't vapor lock or detonate nearly as much when using the additive, especially helpful in hot weather, and it cost about 1/3 of store bought octane booster, with almost identical results.
• You may need to change your fuel filter shortly after beginning to use this additive regularly because it will de-sludge the gas tank. Luckily fuel filters are usually cheap, and easy to replace. After replacing mine once I haven't needed to again.
• Acetone, and xylene are strong chemicals, use gloves, and other PPE(personal protective equipment) as necessary in a well ventilated area. Wash exposed skin immediately. Above all else use common sense(no smoking while mixing, don't get it on clothes, use chemical resistant plastic containers etc...)
• Acetone will eat car paint!!! Dispense into your car's tank carefully with a funnel.
