B20?

Just want to get everyone's opinion on B20 Bio-Diesel. There is a station near me that's getting ready to sell it. I know you have to change the oil sooner. Does your performance get reduced any? Any loss of power? Loss of mpg? What are the benefits of using B20? Just curious and trying to explore my options. Any input from those that have used it would be great.

If the B20 is to spec, you should not notice or have to do anything.

If you have crap in your tank, the B20 will clean it out and plug your filter.

Do you know what their feed stock is? WVO, Soy and Algae are the three bigger players nowadays.

I like B20 for the higher Cetane rating and the WVO stuff gives a hint of McDonald's to the people behind you.

If you go any higher than B50, you will need to change oil more often and worry about gelling in cold weather.
I always stayed away from B20 until i was on a long trip and the only place within a few hundred miles had B20 so i was forced to use it. results were, smoother running and better mileage. If i can fill up with B20 i would everytime. But where i live there is no B20 anywhere. Just food for thought.
Thanks for the responses. I've only ever used B5 before but that was in my old truck. Same thing,middle of nowhere ans it was the only choice. No difference. The station by me should be the better stuff, it's a chain (Mapco). But I'll check.
I have never found improved fuel mileage when using Bio-oil. I have track from new on my truck every gallon of diesel that has gone into it for fuel mileage. I can tell from bi-monthly fill-ups and daily fill-ups when I tow instantly when Bio-fuel has been used as my mileage drops off.

Now there is a chart that compares BTU's of different energy sources of fuel to one gallon of gasoline. Diesel fuel has 113% of energy compared to one gallon of gasoline where as Bio-fuel such as B20 has only 109% of the energy of one gallon of gasoline. This may not seem like much difference but over a year's time it does make a difference especially when towing my 5er.

Now the 2013 Ram trucks are approved to use B20 fuel as where the older 6.7L 07.5 to 12MY's trucks where only approved for B5.

I only run b20, I have been running it consistently since 2007, my current 2012 truck has only had b20ran through it, I did add a severe duty filter kit, but your 13 truck has a frame mounted water seperator from the factory. I have never had a fuel or engine problem with any of my dodge trucks, nor have I ev had a fuel filter plugged. I say go for it :thumbsup:

On the older 6.7 trucks if you add a mopar severe duty filter kit, they can re flash your computer and enable a b20 function that will allow the water in fuel light come on sooner. :thumbsup:

If the station didn't sell b20 before I'd stay away for little while, unless they are putting in in a fresh tank. Like stated above it will clean out your fuel tank.....and that goes with the stations tank as well.

Thanks! The station is a rebuild, completely torn down and built bigger (they bought the property next door) and the tanks are new. I'll probably give it a try eventually.
in MN the % of bio goes down in the winter.


B20 by 2015

In 2007, Governor Tim Pawlenty unveiled a plan for taking the state's biodiesel requirement from a 2 percent to a 20 percent blend in diesel fuel by 2015. Pawlenty’s “B20” proposal was signed into law during the 2005 session and modified in 2008 to set intermediate blending mandates of B5 by May 1, 2009 and B10 by May 1, 2012, with the implementation of B20 by May 1, 2015.



According to the statute, the requirements for B10 and B20 will only be effective during the summer months (April through October). In winter, the mandate will revert back to 5 percent unless state officials and technical experts determine that accepted federal standards deem certain higher blends as suitable for year-round use in Minnesota. In addition, before implementing blending requirements above B5, state officials must ensure that a variety of conditions are met including sufficient fuel and/or feedstock supply, adequate blending infrastructure, and the existence of federal standards for mandated blends.


ps The more Bio% the lower your fuel millage will be.

Never even heard of it. Might just stick with good old D.
I don't like any of the Bio-sludge crap. Oregon has a mandated 5%. IMHO the Bio's are an answer to a problem that didn't need fixed. Much like E10 gas...

That said, you can get options in Oregon up to and including B99.

I don't know about other states, but it is common practice to blend Kerosene in the higher % Bio's in the winter for anti-gelling.

I do not want to use B20 at all. It is bad enough that the state government is providing tax incentives to refiners that provide higher concentration of Bio-fuel. I know the Meijer’s brand in Northern IL is using B11 during the summer months. I asked the tanker driver who was dumping diesel at the station at the time if the fuel had a BIO mix --Yes. He stated that the winter blend was straight D2 with anti-gelling agents also.

I also use the Big-Line kit from Glacier Diesel this has an extra fuel filter which is after the factory filter but ahead of the CP3 pump. This is a 3 um filter and the factory is a 5 um filter.
