Because Illinois mandates more than 5% biodiesel, Mercedes Benz would not sell diesel vehicles a few years ago in Il. because they don't recommend anything more than 5%. After a couple of years they started selling diesel vehicles again with the recommendation of shorter oic's and more frequent fuel filter changes. They were also going to eat more warranty work. Far as I know they still say anything more than 5% voids your warranty. They really don't like biodiesel in their engines.

I suppose, but I would guess those mostly come from folks with some sort of an agenda. I have used anything from B2 on up thru B20 for most of this century, upwards of 20,000 gallons of fuel a year, and do regular UOA's on my commercial trucks and have never seen any fuel dilution on Cummins and Detroit engines. I fuel frequently in Illinois and Iowa where the bio is usually between 10% and 15% most of the year. Only drops to lessor levels in the really cold periods of the year.

none of the fuel where i live contains any biodiesel. it is available in three grades though and there is 20 cent difference between the two
1 is ultra low sulfur road diesel
2 is low sulfur road diesel

You might want to check Flying J / Pilot, Loves, etc truck stops. I drive commercially and I have yet to find one any where, including KY, that doesn't have bio blend diesel. Keep in mind, a retailer is not required by federal law to label the pump if the bio blend is 5% or less. Check with the station manager.

And you are misinformed. There is no legal low sulfur road diesel. Only ULSD. Been that way for about a decade. Some off road diesel might be LSD, but even most of it is ULSD. And off road diesel does not have road tax on it, which would explain the price difference.

No mention of any bio-diesel here in SE Virginia on any diesel pumps I have seen. Flying J sells biodiesel mix in Suffolk 30 miles away, buts 30 cents more per gallon than the $2.73 at the WAWA 2 miles from my house.

I drive a MB with OM648 motor & they recommend no more then 5% bio. I fill up at Walmart with high turnover the Label say MAY be 5% bio. Never have had any issue with it yet.

I don't know if I have yet seen a diesel pump around Atlanta that does not have the B5 sticker on it. Seeing that lubricity is quite a bit better with B5 vs B0 I think I may stop spending the coin on DieselKleen Silver, might still run it through here and there for cleaning but for lubricity seems like it may be overkill.

Like Mercedes - VW/Audi does not approve blends above B5. Not sure if they know something us consumers normally would not or if they are just concerned with quality control of the bio portion of the blend. Who knows.

The only place that Ive seen it mentioned was Sunoco, B5. Ill check next time I fill, theres a newer sunoco station that is actually pretty competitive with the no names around here, 2.99 vs 3.07

On the flip side there are now 15% ethanol blends (E15 in the states) for gas and yet stuck with B5 for diesel. I honestly think its mainly a quality control concern with the biodiesel producers since it is a much newer "technology" vs Ethanol. I'm thinking as we move down the road higher blends will be approved, but who knows if diesel passenger cars will still exist in this market after VW dieselgate.

I went back today to fill up the GL, and saw no specific labeling besides D2. Maybe since NJ is so bad with labelling, they also do not need to disclose ethanol percentage, so its possible they just dont put it up. On the plus side, both of the diesels saw a 3-4 mpg improvement with Sunoco. Not sure if it was just a fluke, I went with Valero in the tdi to see if theres a change.

Thread on the additive forum with a fuel delivery driver in GA. I asked this and he said all D2 manifests when he loads have an asterisk that says load may contain up to 5% bio. The dreaded "may" that doesn't tell us anything although if it was always zero there wouldn't be need for an asterisk.
