UPDATE:

Not much to say. 1,500 miles since the conversion and all is well. I was concerned about premature engine failure during the first 1k miles, now that i'm past that milestone I think she'll run trouble free for a long time. I would like to add another 30 gallon veggie tank so i don't have to fuel up as often. I have No real problems to report.

With the price of gasoline being so high, i've been using my skoolie as a daily driver. I love driving around for free!

I am very very happy with the conversion. Why didn't i do this earlier? If anyone would like more info or would even like a helping hand to convert their diesel, feel free to contact me.

Lapeer …it’s Great to hear the Veggie-Oil conversion worked out so good for you.
Driving around for mostly nothing sounds very, very appealing to me.

I heard of folks doing this but never got much hands-on info on it…really appreciate your run down on how you did it.

But…now that I’ve learned it worked out so good for you ….
I’ve decided to get rid of our Gas Bus…Buy a halfway large Diesel Truck (covert it to run on Veggie Oil ) and build a big 5th wheel trailer to tow behind it.

Gee Thanks

I just picked up a pretty interesting Book called “From The fryer to the Fuel Tank” written by Joshua Tickell that gives a pretty comprehensive explanation with lots of charts & pics on doing a Veggie-Oil conversion…that should help me.

2,500 miles since the veggie conversion, and still going strong.

I've been taking the bus out on a trip nearly every week this summer. I have almost every fri-sat-sun off of work, so I have a lot of time to play.

Before the weekend, I plan to add a second veggie tank. It takes me longer to set up the pump and other items necessary to filter the oil than it does to fill my tank. There is not much more labor involved in picking up 60 gallons instead of the 30 gallons the bus now holds. I'm currently able to filter about 10-20 gallons per minute of veggie oil(depending on what kind of oil i use)
Before the trip to burningman (michigan-nevada and back) i would like to add another 30-60 gallon capacity. Having 120 gallons of veggie and 40 gallons of diesel would be very convenient.

Why not use a real drain system? Might come in handy. Personally I think the fuel tanks on everything ought to be able to be drained fairly easily. Lots of junk ends up in them.

There doesn't seem to be a system in place (currently) to collect taxes from individuals regarding Bio-diesel or the use of waste diesel as fuel.

My husband spends a lot of time in a restaurant (Huddle House) in the town he works in during the week. The restaurants in that town simply pour their waste oil down the drain and it collects in a tank. The water and other stuff that goes down the drain simply passes the waste oil on it's way to the town's sewer system. A pumper truck comes in and pumps the oil out of the tanks. He has talked to the folks down there. We have discovered that you might have a hard time (in some places) getting the restaurants to "retrain" their workers to save the waste oil for you. Haven't checked with the Oriental restaurant that we frequent yet. Waiting for you to blow up your engine At this time we will still watch others....

"waiting for you to blow your engine"

Gee, thanks!

In this area, i've noticed that almost every restaurant has a grease dumpster out back next to the garbage dumpster. The biggest problem is finding oil that is liquid at room temperature. It seems that only about 25% of my local restaurants have oil that is liquid at room temp.

I've checked all the grease dumpsters in my local town so i know where the good stuff is. however, If i fill up out of town, i sometimes have to go to quite a few different places to find "good" veggie oil.

every restaurant i've visited has always been more than happy to let me take their waste veggie oil.

This subject was brought up on MAK's busconversion board and on Ian's Busnut online forum. Most of the responses on it was disheartening at best. I had also read (many years ago somewhere in all my extensive reading) that the guy who invented the diesel engine was a canny sort of guy and developed the engine so that it would run on pretty much anything even vaguely resembling fuel (I think he had trouble with the water as fuel, although I had read about rumours that after WWII there were a few that were running on diesel heavily mixed with water... never ran into any books that specifically said where they were just "in a town", so may have just been extraggeration to point out how tight things were). So I really can't see where as the veggie oil or biodiesel could hurt the diesel engine. Only trouble engine-wise I can see is if the fuel causes the engine to get too hot (not likely) or if it causes some of the fancy electronic/computerized engines to have problems since they aren't "programmed" to handle diiferent stuff. It's a good use for Canola oil, I'm a bit leary of canola so try not to eat any, and that Mutated soy stuff that Monsanto is pushing on all the soy farmers (they can't kill it out since it resists Roundup and right now most of Europe won't touch the stuff. If US/Canada refuses it, the farmers will need to do something with it).

i think i mentioned this once before, but the brazilian made 6.6 liter ford was originally designed and used as an off road heavy equipment engine ie: tractors, dozers, ect. I think that alone probably made for a simple, rugged, reliable motor. Coupled to that is the fact that many are used in brazil and i would immagine that the fuel quality there is not as good as here in the states so it would make sense that the engines were designed to handle the "dirty" fuel. Diesel fuel isn't exactly "clean" anyhow. The stock bus fuel system is only filtered to 30 microns. The human eye can see particles that are 40 microns and larger.

I have no idea how long the engine will last. There are nearly 270,000 miles on the original engine. The past 2,500 miles have been driven primarily with veggie oil. From the reading i've done, it seems the injector pump is the weak link in the veggie system, luckily the bosch inline pumps (that's what my bus has) seem to be the most tolerant of wvo.

There is nothing in my bus that i can't live without. I've only spent approx. $4,000 total on the project. and i've gotten at least a year and a half of use out of her. The worse thing that could happen is that she sufferes total thermo nuclear meltdown (ie: throws a rod through the oil pan, or blows a hole in a piston) far from home. Then i'll have the bus towed to the nearest scrap yard and i can go greyhound.

Even if (when) the engine fails in the bus, it cannot necessarily be blamed entirely on the use of veggie oil. 270,000 school bus miles are A LOT of hard miles for any engine!

Wish me luck! i'm leaving in about an hour for a 450 mile round trip this weekend.

I had to visit almost 20 restaurants before i was able to find suitable vegetable oil while i was in traverse city. That was inconvienent, but i didn't bring enough money to drive the 200 miles home on diesel fuel.

Eventually a chinese restaurant came to the rescue and i filled up my twin 30 gallon fuel tanks.

About halfway home, the bus started having diffuculty climbing hills and generally seemed to be making less power. I was pretty sure my fuel filters were getting plugged up. The bus had been having trouble with cold oil for about the past 800 miles, but had been fine once the oil heated up. Now it was acting like she was running on cold oil even though it was well above 150 degrees. I only had one replacement filter, and i really needed two. I stopped and replaced the main veggie filter @ ~2,800 miles driven on veggie. This fixed the problem for the next couple hours. About 50 miles from home, the bus slowed down to about 35mph and woulnd't go any faster. I switched over to dino diesel and the bus ran better, but still not good. The rest of the trip i could only cruise about 45 mph using diesel fuel. The engine would barely run ont the thicker veggie oil. It was sunday evening, and there was no place to get a new fuel filter.

I purchased the new filter after i got home and the bus now runs fine once again. I've driven another couple hundred miles since i changed the filters and everythign is excellent!

the lesson: always carry extra fuel filters!

On water removal, good cooking thing I learned, The reason all these biodiesel sites say chinese restaraunts have lower water content in fuel is that traditionally in chinese cooking a brass basket is used to remove the food, for some reason the water clings to the brass, maybe that would be helpful in the oil treatment process.
