Biodiesel & 2008 Duramax

[jack_usa]

I have a 2008 Silverado 2500HD with a Duramax.
I saw in the manual it says it is approved for B5.

Now does anyone know what would happen i went for B100? Will i damage the engine? Does the new pollution control junk imposed on diesels starting in 2007 make this impossible to do?

I was thinking of making my own B100 with WVO kit to keep fuel costs under control.

I am wondering if i am better off trading it in for a 2006 model with out the restrictions and having the freedom to fill it with what i want.

Any thoughts on this would be helpful.


Thanks so much for any guidance.

I will reply on the specifics later however for now I must say just this. The older the diesel, the better off you are for running biodiesel. I would try and find a 2004-2006 with low miles if you are that serious about making and running home based fuel in your truck.

That is an option or you do what I would do;buy an older (not to old) VW,Mercedes,etc. This will combat fuel costs better then any truck. Regardless of how old your truck is, I am sure it wont get 50MPG highway like a VW GOLF TDI. Just my two cents.

I look forward to more detail on your part. I talked to the GM dealer and he told me that the duramax engines are the same 2008 vs 2006 but they just added the particulate filter and somehow it is weaved in through the elaborate computer system, so i don't really know that will play into it. He did say that if i have problems the first thing the dealer does is take a fuel sample and if it's not what they recommend (anything besides B5) then the warranty if voided.

So the question is what parts are affected by running B100? What is the long term effect of running B100 and can it be retrofitted relatively easily to accommodate the fuel? What parts specifically are the problematic one?
Thanks!

Running B100 in a new emission equipment truck/car is tricky. Look at other posts like biodiesel and lubricity as to why this is a big problem. I have good info in there about the subject. Read up on that and then post in here to ask any further questions.

All in all, I must say that that the new emission equipment would get "clogged up" with B100s after burn of high nitrogen oxide content. The dealer would easily see this as a red flag because your emission equipment is attempting to scrub excessive amounts of nitrogen oxide molecules out of the exhaust.

No retrofits are known as of yet and the new equipment is just that, new. 2-3 years in the making and no one has a real grasp on using B100 with the new emisson standards. I do know that the new Jeep Cherokee diesels can take B20 per Mercedes Benz giving them the 'okay'. However I am not sure that they are compliment motors for the 2010 emission rules. I.E. Possibly no new emission equipment yet, which means they are probably only 45 state legal. Furthermore, They still have two years to comply with the new regulations and frankly they may phase these older CRD motors out by then with something newer and more up to date.

So my advice, read some older posts in this forum on the subject and see if that answers your questions. If you have anymore questions, feel free to ask. Though I am no expert on the subjects, I do know a lot about diesels, the new 2010 emission standards, and biofuels. Ironically they are all linked. Again no expert but a big hobbist on the subject at hand.

Cant run B100 will cause problems with the DPF

[jack_usa]

First things first. Ordered Quadzilla and a new exhaust. The DPF will be hanging out in the corner of my garage gathering dust particles!
Can't wait to see how the mileage improves. Then i'll start working towards B20 or higher. Let you know how things go.

[boyeraz]

Let me know what set up you are going with and how well it works. . I am also looking at shit caning my dpf.

[jack_usa]

Believe me i'm waiting for UPS to come, it'll be like santa at Christmas! I can't wait.

My goal with this is the best mileage, and i'll take what ever extra horsepower that comes along with it.

isnt it nice how all the crap they put on our trucks to clean up the air, when just changing our fuel to bio fuel instead of fossil fuel would help out allot better.. plus in other countys they have no emmisions standards and they just pump out crap to our planet

By the way i installed it. DPF is now in my garage. And i went up a solid 3mpg to almost 18mpg on my first tank.
Plus the extra 50hp is a nice kick too
Thanks again to DSTRBD for his help!
