There is no across the board enforced standard for purity of product. Since there is no reliable standard for quality product yet, Cummins won't bless if. If it's made correctly clean and pure there's no problem with it. Several studies have been conducted running pure b100 for as many as 1,000,000 miles in a Park Service Dodge Ram with no problems. I've run B100 for maybe 15 tanks, and had no problems. Even my fuel filter still looked clean after running 4 or 5 tanks(busting the dislodging all the crud in the system myth). Runs a bit smoother and quieter, gets slightly lower mileage, smells like stir fry exhaust.

Thanks Mike. I am going to look for oil and oil sources for the rest of the year and if I can get enough supply am going to take the plunge.

 

If you decide to take the plunge, or even before, go to:

http://www.biodiesel.org

Sort of a clearing house for info.

I've got a few other links as well as a book with a plan to make the "Appleseed" Reactor. The process described uses Waste Veggie Oil like the fryers in your local McD's or some such.

Pretty interesting stuff. And with the price of Diesel skyrocketing here in Rural Nevada, I'm seriously looking at building the reactor this winter and trying it out next spring. Earlier if the fuel prices don't level off.

 

was b100 ever approved in the 2nd gen ram motors? I've heard of people running b100 in them but never bothered to investigate whether or not it was adviseable. also there is the WVO conversions out there... havent heard of any aprovals for that on anything but it still gets used.

 

Jimmydaleo.Cooler temperature is were i am Northern Canada
we by the end of october and this morning i have some ice to scrach from my windshield,in the end of january and mid february will get low of -20F in the day and -30F in the night.If u havent felled those temps before
just know that when u are breathing by the nose ur nostril sticks to each other close if u dont take care,
if u sthick ur bare hands whit some moisture on them to bare metal thell stick to it.

Here guys who run bio cant run it winther cuz it like butter,not liquid anymore.
But i know a guy a chimist who still running it,he use 2 tank ,1 diesel,other is a heated veggie oil brew
but when he shut his truck off he have to swtich tank to let real diesel enter the lines and pump and all else he got to warm the whole truck to make it run again

 

Hey Steve

I don't believe it's been approved for ANY Cummins motor beyond the B20 mix. B100 is a gamble no matter which way you slice it, but living in Nevada has taught me to take the occasional gamble.

Jimmy, just make sure to be very careful on the temperature aspect. It is my understanding that Biodiesel will gel at about +40 deg. F. That's pretty damn warm in my opinion. Standard number 2 diesel supposedly gels at about +10 deg. F.

The high gel point is what would keep me from running B100 during the winter here.

 

hell I'd be happy to have access to the good diesel #2... (LSD vs ULSD)

Lance, up until recently, the best mileage I'd ever gotten on my '05 was after meeting you to drop off the TB... 18.3 mpg on the stock tires. since then 18.8 and 19.0 only 2x...

 

Here it is from the horse's mouth.

Good reading, but pay attention to the last paragraph since this covers all Cummins engines.

 

Thanks guys a lot of great info here. I am going to work on a source of oil, If I get it I will upgrade fuel system first and stock up on a few filters. I want to take the plunge on this so I can enjoy the truck more and more. Hell the more money I save in fuel, the more I can put into upgrades.

 

Well Steve, you're doing better than me. I can't get mine about around 15 mpg. Sometimes worse depending on the maniac mood I might be in.[sm=gears.gif]

Dave, I guess that settles that doesn't it.

Jimmy, about all I can say is that study and research biodiesel before taking the plunge. One of the biggest items you have to come by is a home water heater.

I've been looking at Biodiesel for the better part of 2 years, but only recently have I really started getting interested. Again, price of petroleum diesel now makes biodiesel very attractive. It also helps that my landlord just replaced the water heater in my house and let me keep the old one. Hehehehehe Mad Scientist in the making.
