I agree that reading here will help you much. The basic idea is to filter the WVO down to 1 micron. You can do this using filter bags or wound filter element.

Christy:

Filtering the grease is only half the battle. You also have to ensure there is no water in the grease. There are many methods for this, but essentially it is heating the oil, and letting it settle. Read, read, read. There is plenty of info on filtering and dewatering.

PM me if you have questions. Hippies need to stick together.

Ditto on the Reading and Reading some more. There's a ton of information out there - you could read all day every day for two weeks, and only scratch the surface of opinions, but you should need less than that to get you rolling.

I worry about what seemed to be implied in your post, that you seemed to have the impression that filtering before putting in your car was optional. I hope that's not what you were told. Considering that there is a whole subsection of this forum simply about filtering, you should have an idea of how important it is.

Somebody else said, you can either filter well before the oil goes into your car, or let the on board filter do it, but if you go that route, be prepared to spend a lot of money on on-board filters!

here's some good reading to get you started:

Read the link in brian miller's post to get you rolling, as well.

If I were you, going on that trip, I would see if I could find some folks in Ny and on the way who will sell you some oil. Check out their filtration setups and get ideas that way. I would not even start setting up a filtration setup until you get to fla - no sense in it. do it right, set it up to be permanent, in a place where spills will not be a problem.

one final thing - you will need to warm up and purge and run on diesel for longer than one mile. You should never switch to VO until your engine is fully up to temp. you also need to have vo at 150 degrees or so for it to work right. you need to purge for somewhere between 30 and 60 seconds (probably) and then it's usually a good idea to drive on diesel for a couple miles after that before shutdown.

good luck.

Now mister, the day when my number comes in, I ain't never gonna ride in no used car again.

1. Am I going to need anything different for my kit being my car was converted in tropical weather, and will now be functioning in freezing weather (I'll be near Canada!)

If your car does not have a flat plate heat exchanger, you will want to add one. Plenty of info on the forums about FPHEs.

2.How can I tell when my car is hot enough to switch to veggie?

When your car has reached operating temperature, you switch to veg. Depending on your vehicle and weather, this could be between 5-20 miles of driving.

3.Anyone know about how long 15 gallons lasts on the highway and/or city?

Should be about the same mpg you get with diesel.
