The Oil I use (currently)

I thought I would mention the particular oil that I use in my Plantdrive kit. The Plantdrive kit requires liquid oil. That is to say no Crisco or hydrogenated oils - it must be flowing at room temperature or colder. It can not be grease, part of the reason is their approach to tank heating and the Vormax would clog if oil congealed in it, as the filter and bowl take a while to heat up. They make this very clear in their sales material.

Currently I am catered at work and I should have this job for another year or so. After that it may change because I am freelance and go from job to job. Some jobs last a day others several years.

The caterer saves the oil for me. Because we are mobile they work out of one of those "roach coach" trucks. They don't store the oil on site, they either give it to the commissary or take it back to they're main kitchen for disposal using the cubees it came in. They don't use large quantities of oil every day but we have fries, Chinese, tempura, and other various items that are fried once or so a week. I would say I average 4-5 gallons a week. They fry the food and they're done with the oil. Currently this is plenty because I live close to work and the Jetta SIPS fuel.

It is non hydrogenated soy* and used once. He sets it aside to let it cool then at the end of my shift I come buy and pour it back into a cubee using a homemade funnel from the Greasecar forum with a paint strainer installed. Evidently soy oil is not the best oil to use because of it's particular makeup. It's more susceptible to polymerization.

Contrary to popular approach, I did not secure a source of oil before starting the conversion. Besides being confused about the whole filtering process I was concerned about "taking over" the oil removal from a source. I didn't want the responsibility nor did I think I would need that much, again this car gets mid 30's MPG. My idea was to do the conversion, get the car working, and in the meantime purchase some new soy oil from Costco. I figured getting a source of oil would be the least of my concerns I also was fairly sure I could get the oil from work (I work seasonally and was not working when I converted the car).

*I have to watch as the have snuck in a couple of "creamy" - READ: partially hydrogenated cubees of soy which I have inadvertently mixed in with the good soy

  1. Hi Joe,
    This a good Blog, but More updates would be appreciated. It is very interesting and well written. I have a 81 vw diesel pickup in the backyard that we are going to convert. Is there any additional filters that should be installed?
