Reusing Deep Fryer Oil to Fuel a Converted Car
If you happen to own a vehicle that runs on diesel fuel, you may want to consider making the switch to reusing deep fryer oil to fuel your car. For a diesel vehicle, making the switch to being able to use deep fryer oil is a rather simple process. For a fairly knowledgeable mechanic, this can be accomplished in about 3 hours. Assuming you have a diesel vehicle, or at least a car that has been converted to run on diesel, you can follow the basic steps below to make the switch and cut the price of your gas drastically.
Step 1 – Converting Your Vehicle for Vegetable Oil
The crucial step that allows your vehicle to run on deep fryer oil is to add a heater in the fuel tank and a heater for the fuel line. The fuel line heater should be located just before the fuel gets to the intake manifold. The reason for these heaters is that deep fryer oil is extremely thick when cooled, and will only clog up your tank, fuel lines, and engine if not properly heated up. The heaters that lower the viscosity of the oil to something comparable to regular diesel fuel are sold in Waste Vegetable Oil Conversion Kits.
In addition to installing a conversion kit, there are a few other modifications you can make. These include using glow plugs with a higher rating, as well as fuel injection ports that are a bit wider. However, these tend to rather expensive, and aren’t absolutely required for running your vehicle on waste vegetable oil.
Step 2 – Getting the Right Oil
Almost as important as adding the conversion kits, is using the right deep fryer oil. The oil needs to be from a natural, vegetable oil source. Some oils have a much higher ratio of animal fats, and will not burn very well in your vehicle.
Step 3 – Where to Find Waste Vegetable Oil
Restaurants are a prime location for getting waste vegetable oil. This is because most restaurants are required to pay for special disposal of their old vegetable oil, and they go through a great deal of oil fast. In most cases, they will be eager to hand it over for free if you ask, since you are already saving them the money spent on disposing of it. Just make sure that you inquire as to the purity of their oil, to make sure you are actually getting a good natural vegetable oil.
Step 4 – Filter the Oil
You will need to make sure the oil is filtered well before use, as you can’t count on restaurants to do this for you after they’ve used it for cooking. Waste Vegetable Oil Filter and Pump kits can be purchased for just this purpose.
After filtering your oil, you can opt to either pour it directly into the gas tank, or mix it with petroleum diesel for less chance of clogging due to its naturally thick, viscous state. For colder climates, this is highly recommended, as it becomes harder for pure vegetable oil to heat and thin out in the cold.
Step 5 – Test Your Vehicle
With your vehicle converted and your tank full of vegetable oil, drive for a few short distances to ensure that your vehicle can take the change.
