I have an 01 and have been considering running a B20 blend with the usual ULSD available next to it. I have been running Power Service White bottle for the past three and a half years and added up my cost and its more than if I ran a B20 mix.

Anybody know a good dilution and if I need to change anything in the fuel system to do this? I usually fill up at half tank and take around 20 gallons.

Thanks, Kurt

The general consensus is that B20 will have minimal to no effect on fuel systems.

Having said that, I would expect to see some cleaning of the fuel system...Bio is a solvent.

Keep in mind that Cummins only recommended up to B5 in the more recent years' trucks.

FYI...I ran up to a B20 concentration in my Passat, last year. Bio shrinks seals; D2 expands seals. I had to reseal the injection pump. The IP is just too expensive to replace vs. the >40mpg I get out of the Passat, to have any value for me to run bio.

I dont see why youd need to mix B20 with petrolium diesel. Why not just try running B5 blend or something?


Now weather or not your truck will like B20, or any Bio, I dont know. Ive read and heard of people running bio in 24V's without a problem, others say they dont like how their trucks begin to run. Id start off with B5 and work my way up.

And when you start running bio, buy a few extra fuel filters. Bio cleans out a lot of gunk in the fuel system and your filters will begin to clog for the first few tanks till its all out.

I was back and forth between B100 and ULSD when the price for B100 was less than ULSD. At any given point I've had between 100% and 5% mix in the tank. The more bio, the less rattle in the engine and the exhaust smells like butt. The more diesel, the more normal it will sound. Getting the fuel filters is a good recomendation. The exhaust won't smell like french fries like most people assume. It will only smell that way if the bio is made from Waste Vegetable Oil or WVO. Commercial bio is usually made from virgin soybean oil so it just smells like oil thats overheating on the stove. I liked the bio in the fact that it is renewable but I wish it was cheaper.

the more normal ... listen to me..

Just carry extra fuel filters and go for it. I believe your engine has been approved for B20 by Cummins. Check your hoses for compatibility with Bio also.

I have an 02. I think the owners maual says 5% max, acoording to Cummins.
I think they good cause to say that.
Why not just run some 2 stroke with ULSD, like many on this site do?
If Bio causes any problem with your motor of fuel system, it will be expensive.

annabelle

I believe Cummins took it up from 5% to 20%.

FWIW, they switched us from straight Dino to, and I quote " A Biodiesel blend ranging from B5 to B20"

I have not had the first problem yet.

infidel

You are right. They announced last year that B20 is ok for all models up to '06.

Thanks, I was just pondering the idea. The Bio is around 3.50 a gallon right now around here and I think I'm just going to stick w/ PS for the time being. Thanks for all the input!

Around my parts I get B5 thru B20. My injection pump has never been so quiet and I like it. Better lubrication is always a good thing.

Nothing lubes better than B5 or better. However, only the new style lines and pumps can handle the richer blends, B20 and up, of Bio. If it's fuel cost, you need to look at MPG as well. There are less BTUs in Bio than regular Diesel. I think most Bio is around 135k and most Diesel is close to 142K? Then again the Cetane comes into play with Bio being higher, Bio is around 52 while Diesel is (probably) close to 42 on avg. It may or may not make a difference. IMHO Bio is GREAT if it's run @ 5%.

I worked up to a B20 blend this summer, and it's running fine, and fortunately for me, B20 at the pump costs less that full petro diesel. I'll bet if you look at the BTU numbers of the new Ultra Low Sulfur Diesel fuel, it'll be close to that of biodiesel now. Removing sulfur not only decreases the lubricity, but BTU content as well.

your 1st sentence says it will have minimal effect on fuel systems, but then you say that it ruined the seals on your IP in your VW. Sooo.... what're you trying to say? How many miles were on the VW at the time? Could it have been normal wear and tear, or do you feel that it was definitevly caused by the bio? I am just curious here. I dont run bio, nor do I intend to.
