VW Cold Start On WVO

Old Stinky gave me a little scare today. After some serious loss in power, I changed her fuel filters, only to find the problem got worse. I was pretty much running 100% WVO (Waste Vegetable Oil) at the time, and thought I was in some trouble. After driving some 100km to burn up about 8 liters of oil, I went to the gas station to top up the tank with $10 of diesel. The diesel didn't help. The car wouldn't idle, it would die at every traffic light, sputter, and lack power. After a day of thinking about it, I got into it, and found an air leak at the new filter, sucking air in. I double hose clamped the fuel line, and its running top notch again.

Running 100% WVO has its disadvantages. One disadvantage being it is harder to start. In the summer it starts like it is -20c outside. Here is a video of a "cold start" at about 15c. This was when I had the air leak, I think it is much easier to start most of the time, I will make another video soon.

Filtering Fryer Oil

Just a simple vid of my simple cheap fuel filter. The car has a filter to its required specs, this just takes the french fry bits out, that can cause problems with the tank pick up tube and stuff. Even still, be prepared for road side filter changes if you haven't gone through the tedious task of pushing this stuff through a 10 micron filter.

This vegtable oil was progressively mixed with less and less diesel fuel. I now run it at 80% fryer oil and 20% diesel oil. The car puts up a bit of protest starting, but less than it did starting in the winter. That gets me 160 mpg on the diesel fuel I have to pay for.

Soon I will have the biodiesel reactor dialed back up, and I can run B20, 20% biodiesel, 80% fryer oil, and never stop at a gas station again.

This website will go through the process of adding a seperate fryer oil tank for the winter, making biodiesel, dropping a VW diesel into a Dodge minivan with the sole intention of running it on fryer oil, and rebuilding the old vegie truck.
