what percentage biodiesel is neveryone comfortable using? I am new to diee sel and have been avoiding the most convenient station after I found out it used 5 % biodiesel. filled up there once and seemed to get lower mileage, but to be fair truck only has 1600 miles on it, and I am anti bio anything somay just be a perception.

just curious what y'alll think as they just opened a bucees near me with diesel at 3.26 but they have some percent of biodesel, will pay more for the dead dinosaurs if they giv e me better mileage as I sujspect but if I am off base I will save the money..

 

I just got back from a trip through Oregon, found out just tonight when I was paying my fuel bill that I had at least one tank of fuel with 5% Bio. Haven't got the bill for the rest of the trip yet so may have picked up more.

But the fuel mileage for the tank with the known Bio-diesel in it was the lowest of the trip. There's more to the story though lots of hills and then when we came out into the open we had to buck a head wind. So the numbers are meaningless really, for the sake talking about Bio-diesel.

 

I don't think there is a station in Texas that sells diesel at the pump without at least 5% BIO. I just make sure I add 8 oz of PM-22 to every fill-up (30 gal).

I don't like the BIO but it is a fact of life for Texans so I've learned to live with it. In fact the BIO is probably good in one respect as it adds some lubrication to the super dry diesel the EPA has forced on us.

 

6.7 is rated for 20% bio.

 

I just got back from a lengthy trip wherein I coul dcontrol a LOT of variables. The mileage I rec'd out of #2 deisel was 21.5 (give or take some terrain). When I put biodeisel in it i got around 18.5.

Truck was unloaded; I kept my foot out of it; and I did NOT hand-calculate the variance. I used the computer. flame me if you will but that is the best mileage I have seen since owning this vehicle.

 

I add 4 oz of PM-22 at every fill up. I try and run it down to 25 to 30 at each fill up.

I think Oregon might be the same as Texas with the 5% Bio, I don't have a problem with it, as senix said our trucks are rated for 20%

 

That seems like a big difference between the two. I have never got that good of mileage with my truck, but it is a DRW and low gears, and I live and drive in the hills.

 

I'm surrounded by blended biodiesel fuel here in the cornfields of IL, and there is a big mileage drop with it. I found that when I drove out of state tot eh south for fishing trips, I easily made 3-4 mpg more with 'normal' diesel.

 

X2 on that. No one really knows just what % of bio you get. kinda like gas and corn squezzins. Its not monitored and can vary alot.

 

are they required to post on the pump if they nare using 5% biodiesel? I have only noticed it at one station and not the other couple I went too, of course I am new to diesel and only filled up a handful of times so far.

 

Per Oregon state law, All diesel fuel sold in the state must be blended with at least 5% biodiesel (B5). Diesel fuel blends sold between October 1 and February 28 may contain additives to prevent congealing or gelling.

Washington on the otherhand is a biodiesel leader and has more laws and incentives but mostly applies to state/gov't fleet vehicles.

At least 2% of all diesel fuel sold in Washington must be biodiesel or renewable diesel. This requirement will increase to 5% 180 days after the Washington State Department of Agriculture (WSDA) determines that in-state feedstocks and oil-seed crushing capacity can meet a 3% requirement.
Pumps dispensing biodiesel blends of 5% (B5) or less must include a label stating that the fuel "may contain up to five percent biodiesel" and those distributing blends greater than 5% must be labeled with the capital letter B, followed by the numerical value volume of biodiesel and the words "biodiesel" or "biodiesel blend."

Both WA/OR have strict quality control measures or so I've heard. I've seen them taking samples and doing on-site fuel testing in Oregon.

In comparison a state such as Texas seems to be like the open range.
Biodiesel blends are considered compliant with Texas Low Emissions Diesel Fuel (TxLED) regulations if the diesel fuel is compliant with TxLED regulations and the biodiesel meets the requirements of ASTM specification D6751. Biodiesel may be added to any TxLED compliant fuel at any ratio without additional additives. Biodiesel blenders are not considered diesel fuel producers and are not subject to TxLED reporting requirements. However, blenders must maintain records of product transfer documents and make them available upon request to the Texas Commission on Environmental Quality, U.S. Environmental Protection Agency, or local air pollution authority for a minimum of two years.

 

I was just down in Myrtle Beach, SC and went to fill up and read on the pump bio 5% to 20%. And at other pumps bio 5% min. I do know that in CT a lot of the diesel is going to different stations from the same distributors. I do not know what our law requires, but I'm sure there is some bio % in there. Just a note I got better mileage down there by 3 to 5 mile than when I am up here. It is what it is.
