Looking for DD Diesel/Bus mechanic in North Florida/Georgia

[freds]

I looked at making biodiesel https://www.utahbiodieselsupply.com/makeyourownfuel.php and you have to do a bunch more steps using methanol plus lye and then you have to separate the waste glycerin out.

So at the time concluded just burn it directly.

I haven't looked into it recently, however do hear that the supply is much tighter out there.

PS. Just checked craigslist and a local guy is giving away 900 gallons and one state away someone else is selling virgin oil for $1.50 a gallon.

We sell our waste oil from the restaurants here in the Phoenix area they supply the tamper proof tanks and steam clean the area after pickup each time.They have a processing plant where it is processed to Western Refinery specs before Western buys it, quite the operation to meet all the state. EPA  and county environmental laws.I have seen tanker loads of alcohol hauled in for the process the ratio I have no idea what it is

Where are you located?

FredS,

I ran Straight Vegetable Oil (SVO) in my 1998 VW Jetta TDI for several years, until 1) my commute dropped to only 22 miles each way, and 2) SVO got a lot harder to find after the GOV mandated that all diesel had to contain Biodiesel.  SVO went from being a waste that restaurant owners had to pay to have removed to a income stream that Biodesel manufacturers were paying for!

I don't think I could find enough free, and or low priced enough today to make economic sense.

The keys to successful use are 1) filtration of the SVO down to the under 5 micron level, 2) using heated oil after the engine is warm, and 3) purging the lines back to the SVO tank with diesel about 5 minutes prior to shutdown to clean everything out.

My Jetta ran great on it for about 3 years @ 105 miles per day/ 5 days/week.

I have a pretty regular supply.  It's works great for me and I save a ton.  I was just curious where you live because if there is someone with 900 gallons free I'd like to stock up.

I'm a food vendor at music festivals...all of the other vendors gladdly give me their oil at the end of the weekend.  It's only 3 days old and I'm getting it immediately after being 350 degrees....so there is not water.

Unfortunately...that source and my whole job has dried up for the time being...but I don't have to travel so I don't really need any 😆

But if I can hit a gold mine everyone in a while it wakes the beginning of the season a lot easier...whenever that will be.

With old DDs you only have to filter to 10mic ...the system was professionally installed years ago...but that's what the guy told me.  It's got prob 250k of veg miles on it.

The veg in my system is actually heated at 5 different places.  The system was designed from the ground up to be used in any weather/conditions.  I've run veg in 20 below...just took a little longer for the veg in the tank to actually melt

WVO sure makes a mess of the fuel tank on buses they are nasty from the return if tied into the tank 

[TheHeavenlyChillbillies]

The veg and diesel tanks have separate send and return lines with separate controls. They branch off about a foot before and after the engine.  I should probably wait a few seconds before switching the return lines when going from veg to diesel but I do not. 

So, when I switch to diesel, the amount of vegetable oil from the fuel pump to the other other side of the engine, that isn't used by the engine could go in to the diesel tank.  Maybe somebody could venture to estimate how much volume that is...but it's already filtered...and getting dissolved into 20-100 gallons of diesel fuel.  I also only do that switch once or twice per day of driving.  Do you think it would make that much of a mess?  I've been in there with an endoscope...and it looks pretty clean in there.  Now the inside/outside of the veg tank and that whole luggage compartment...that's a whole 'nother story...holy crap is that a big sticky polymerized mess

The filters inside the injector filter at 5 micron's  and veggie fuel takes a toll on those over time

[TheHeavenlyChillbillies]

So do you think cleaning or replacing the injectors may help with power issues?

How hard of a task is that is that on a 8v71...I've replaced injectors on a Ford IDI in the past.
