Bio diesel

I think I remember some negative comments about bio diesel. Well, we're traveling around Minnesota and that's the only diesel to be found. What damage are we doing?

I used Biodiesel in a couple of tanks going through Nebraska. I know some manufacturers specify up to B5 only, although the pumps I used in Nebraska only stated the biodiesel was between 5 and 20 so I don't know what level I pumped. I have a 2015 Ram 2500 Cummins which is supposed to be good up to B20. I didn't experience any issues.

Bio diesel

The issue is warranty. Mercedes Benz states no more than 5% bio, or B5. If you run a higher percentage of bio in your MB and have a problem, I can see where they could deny warranty coverage......

Biodiesel over B5 will damage the Mercedes BlueTec DEF systemó and void the warranty for repairing same.

To further Protag's point, I found this:

----------
In the case of Mercedes-Benz, their advanced BlueTEC diesel engines inject some fuel on the exhaust stroke, but since biodiesel has a higher flash point than petroleum diesel, the biodiesel does not combust allowing the biodiesel to collect inside the crankcase of the engine itself. This crankcase sludging is irreversible and over time can lead to catastrophic engine failure.
-----------

The big worry here is the comment that the sludging is "irreversible", indicating that even limited use of anything greater than B5 can cause permanent harm.....

I don't know that you're doing any damage, unless it is specifically prohibited for your engine.

We have always put it in ours.

I don't understand why VW and Mercedes diesel vehicles are only good to B5 with all their experience in diesels. All it takes is the bureaucrats to force all states to pump B20 to render VW and Mercedes diesel vehicles doorstops. I would never purchase a diesel that wasn't B20 compatible. As I stated the biodiesel pumps I experienced never stated the exact blend.

Without testing, you cannot know the levels of Bio waste in the Diesel stock. Here in Texas, we are told "diesel is blended at the local distribution center to match customer specifications because it will separate after time making delivery of specific fuel is not possible ...".... soooooooo.... why is this "requirement" allowed to affect products sold in the US?

It should be noted, even gasoline dispensed with single hose pumps will vary based upon the previous fuel pumped. Businesses selling gasoline will not guarantee the fuel you purchase until 5 gallons of your selected flavor has flowed through the system. (Texas Ag Comm who regulates the verification pumps 5 gallons for each gasoline available at the pump, then capturing test sample) That was a hassle with our motorcycles, yard maintenance, etc...

Texas Ag Comm told us "only buy lower grade fuel and you won't be cheated. Also, if you pump at least 20 gallons into your auto, you should not notice very much difference in performance"

hmmm.. why?

Anyway, sounds like if you change your engine oil and filter more often you should minimize the impact of this federal mandate... That is what I do on my Chevy.

Sure glad we are 'saving resources'... "good luck".

Anything over B5 IS prohibited by the engine manufacturer (Mercedes Benz), and now we know why.

Bottom line appears to be to only use diesel with no bio or at most 5%.

EDIT: I just read a fed govt article that states vendors don't have to mark pumps as containing bio-diesel as long as the blend is less than 5%. So.....it
looks like in the US we have no way of knowing if a pump contains any bio-mass because our govt lets the vendor "hide" that info. Nice.......

The "good news" is if a pump contains MORE than 5% bio, it has to be marked as such so at least we can't pump B20 without knowing it....

Bio diesel is a great fuel, but unfortunately not all vehicle manufacturers are ready for it. It takes certain seals in order to handle bio diesel detergents and not all dpfs/docs can handle it.

Use biodiesel at your own peril cuz the emission sensors are expensive. Had two NOX sensors replaced to the tune of $1,500. Not bio related, MB got the software wrong and caused them to overheat.

Many people have different opinions on what level of biodiesel is allowed or acceptable in an Interstate. However, it all depends on the make and year of the unit. The engines have changed over the past ten years or so and so has the emissions hardware and software. I am sure the 5% biodiesel limit is correct for the more recent Interstates.

Does the engine change every year or two or is it just the computer controller emissions equipment?

If all diesels had DEF systems would there be a need for bio blends?

There's no need for bio diesel now. It's all pc stuff.
