Will Bio void your warrenty?

I haven't heard that it will , make sure you don't use the filtered fryer waste , unless it has been processed to remove water and gliserin[my computor makes me spell bad] ,what is the source that you are looking at. next is any rubber hoses and seals will turn to mush in the long term , with a high % about 50% or more , but I've heard that newer cars & trucks are going away from rubber.

 

Will an 05 with the CP3 injection system work o.k. on unused vegetable oil at say up to 5%?

 

According to www.greasel.com the stories about coking up rings and injectors from using SVO and WVO are bunk. However they do say to only use clear WVO and filter it well. The cloudy stuff has to much crap in it to be useable as a fuel. Biodiesel has been converted from SVO or WVO to fuel by transesterfication which removes the Triglycerides and water etc... and is a much better fuel IMHO than regular diesel. The rubber parts deteriorating was on older vehicles and AFAIK there isn't any problem with modern engines which have newer synthetic rubber parts.

Edwin - the stories aren't bunk as far as svo/wvo use - I've seen the pics from the Bosch study showing the nastiest clogged injectors. I tend to believe bosch more than greasel.com who wants to sell you kits... As I'm sure you are aware, the problems tend to occur when the oil isn't heated to the proper viscosity, etc, etc..

 

I personally wouldn't run unprocessed WVO in any engine unless I was trying to destroy it.
Used fryer oil is full of salt, sugar and other nasties that don't mix well with an engine.

 

I agree. I have to much invested in my truck in both money and sweat to risk using SVO or WVO. Homebrewing Bio is the way I'll probably go. Transesterfication isn't that big a problem and I have the time since I'm semi-retired.

Greasel however heats the oil before sending it to the pump but there are other nasties in the fuel that heating or filtering won't get out. I wouldn't hesitate running SVO or WVO in a home heating oil-burner. That is assuming I ever move to a cold place that needs that kind of heat.

I've read a bunch of university studies , and the one from un. of MS.&Utah used mostly 1st & 2nd genaration CTD and had cummins take them apart for inspection and could not find any problums ,thats with processed oil [ nothing in there but fuel ] it lubed the pump better than the old high sulfur dino oil but would start to cloud at 20 f. and worked fine with regular additives for dino oil.

 

No, running commercial bio diesel fuel will not void the warranty. Dodge and Cummins stated policy is that if there is a failure caused by the fuel, it is the fuel suppliers problem. That is the same regardless of if you use #2 petro, bio or whatever.

All the engine manufactures officially say B5 is fine, and express some reservations on higher levels until more data is in, but this policy statement is over two years old, and I think a lot more positive data has come in during that time.

I recently emailed Cummins on this:

"2002-28: Update - Cummins Position on Biodiesel Fuels
...
Warranty and Use of Biodiesel Fuel in Cummins Engines

Cummins neither, approves or disapproves the use of biodiesel fuels. Cummins is not in a
position to evaluate the many variations of biodiesel fuels or other additives and their
long-term effects on performance, durability, or emissions compliance of Cummins
products. The use of biodiesel fuel does not affect Cummins material and workmanship warranty.

Failures caused by the use of biodiesel fuels or other fuel additives are NOT defects of
workmanship and/or material as supplied by Cummins Inc. and CANNOT be compensated under
the Cummins warranty."

 

The reality of the warranty issue is that the dealer or cummins can SAY that any fuel related problem you may have is the fault of the biodiesel - and then its up to you and your lawyers to prove them wrong/fight it, which rarely ever happens. Therefore IMO if you run bio, keep it to yourself. I know this somewhat goes against the 'I am my own warranty station' concept, but the difference is we all know adding HP will introduce additional strains to the vehicle, whereas biodiesel does not - aside from in older vehicles with natural rubber.

I agree with Edwin - biodiesel is a far better option when compared to SVO/WVO use. I would use a greasel kit only in something like a 80's MB diesel or something like that. The prechamber of the indirect injection helps heat the oil.

 

You Know... Given Germany's reliance and promotion of Biodiesel.... Wouldn't it make sense if Chysler...I mean Mercedes Benz... Just come out and say that they will support....and back..... Biodiesel....... Be and adult and just do it....
Everyone will thank you someday........

 

They pretty much do cover it - they have the same statement as Cummins - we neither approve or disapprove...which means that using it is no different than dino diesel. If you have a fuel related problem that's the fault of the fuel, they will not cover it under warranty no matter what's in your tank... I'm not sure what the concern is, or what more you want out of them..?
