so the price of diesel just went to 4.50 a gallon im thinking about switching to b100 which is bout 4.30 what do i need to do to make the change and what are good additives for anti gel and anti bacteria. any pointers would be awesome thanks guys

 

I am in a much warmer climate that you are here in Florida to start with.
Everyone pretty much suggested going to B99 gradually due to its extreem cleaning properties-MY fuel system was/is VERY clean (to start with) due to constant use of 16oz of Power Service Diesel Kleen in every tank of #2Diesel.
That all said I'd suggest starting with a 20% mix (B20) for 2-3 tanks, then to 50% for 2-3 more all the while having a spare fuel filter ready just in case yours plugs up.
THEN you can jump right to B99.....BUT WAIT>>>>YOU are in Kansas and it is probably already getting cold there...my LOCAL fuel distributor where I get MY B99 said to start mixing BACK in #2 when the temps get below 45*......it is my understanding that BIO will gel-up at higher temps than #2.......NOTHING special needs to be done to the engine to run B99.....MINE LOVES IT!! smoother, quieter, way less offensive smell from exhaust, ect

 

Is the mile or two loss per gallon with bio worth it when they are only 20 cents apart? Keep paying 4.50 for reg. diesel or pay 4.30 and get less mileage so it almost evens out IMHO. The U.S Department of Energy has stated that biodiesel gets about 10 percent less mileage than regular diesel so do the math and see what you are really “saving” by going with bio.<O</O
<O</O

 

Unless there's an existing issue with bugs, no need to worry about a biocide. As far as anti-gel, there are no known effective products for biodiesel, due primarily to such varied feedstock. In most cases though, commercial biodiesel from soybean feedstock is good down to almost freezing temperatures. Your best bet is to cut the biodiesel with pump #2. What I have done in the past is mixed various sample jars of my bio with different percentages of pump diesel, and leave them outside so I can see the effects during different temperatures. In the picture below, it is at 28F, and it is hard to see, but the B70 is beginning to cloud. It doesn't get that cold here that often, and usually if it gets into the teens, B60 is more than sufficient. Obviously, the B100 on the far right is gelled. It started to begin solidifying at about 30F. After it had set overnight as it got colder, is when it fully gelled.

 

MY truck, on Beef Tallow based B99 seems to be getting the same mileage as with #2 Diesel fuel.
Earlier this summer I paid .26 per gallon LESS for it than #2 was at the Sunoco truckstop here-the price varies though...last tank was only .5 less per gallon.
PLUS I no longer have to spend the $6 per tank for DieselKleen
Thats just me though guys......

 

Try 1 gallon of RUG with every 9 gallons of bio (a 10% blend of RUG). It will help (and keep costs down).

 

I'll have to try a sample jar of 'B90 RUG' this winter. I am curious as to how that blend will settle out over time, and how it runs in our 7.3's. If it tests out well, that would certainly be the most cost effective anti-gel for biodiesel.

 

Where is a good source for biodiesel info? Im interested in it, but I know there are a lot of junk websites out there. Any suggestions?

 

What kind of info? You're right, there are a lot of bioD zealots and some resultant bad info out there.

Here is a link from a site I trust with some good background info on the fuel itself and differences from straight oil (they are often confused).

Experimental and Alternative Fuels: an Overview - TDIClub Forums

 

Below is a link to a site which is frequently updated on state of the art methods, procedures, and testing of biodiesel, both commercial and home brewed. His site also contains links to other good biodiesel related sites. Great information.

How to Make Biodiesel at Home

 

Thanks guys.

 

How long have you guys been making your own biodiesel? Or do you just buy it from someone?

 

There is no place to buy it around me at all. I have bought some on road trips a couple times. I was working with a neighbor who was making some and ran that fuel for a few months. Learned quite a bit about low-quality biodiesel and how to recover my truck from it's effects.

 

I have been making my own for about 5 years. I have logged around 50,000 miles on biodiesel so far between my PSD and Benz.

 

Stupid question - what is B90 RUG? I know there are B20, B90, B100, etc... but what is RUG?
