Biodiesel Blends

Reading the manual for the diesel, it seems like they do not recommend biodiesel blends above 5% as this decreases the interval for recommended service like oil changes. What do you guys use? Do you know of any gas station brands that consistently use less than 5%. Thanks!

Re: Biodiesel Blends

You will find that most of the "big rig" diesel stop such as Pilot have B10 and up Bio blends. Most of the retail stations have straight ULSD diesel or B5
(5 percent mix w/bio).

Just check the pump to see if has B5, B10 or whatever on it.

Had an x5 d that said no bio diesel, turns out the gas station on the way to work for the wife had B85, she always went to the green hose not realizing normal B5 was on the other side, three years and 48,000 miles of B85 in that X5 that was not supposed to have any and no issues. Not saying the Fiat engine in our jeeps will like it, but the picky BMW had no issues. I put it in my 7.3 PS every few tanks before a fuel filter change to clean everything out.

Re: Biodiesel Blends

I used B99 in the summer, B50 in spring and fall, and lower levels of biodiesel in the winter depending on the temperature in our 2008 WK for 134,000 miles and didn't have any issues.

I'm putting B20 in our 2014 and would run higher levels, but the commercial supplier I use now just sells B20 at their location near me unless I want to drive across town to their other location that still sells B99.

Re: Biodiesel Blends

Just an FYI for any other new owners, but among all the dire warnings in the diesel supplement about not doing anything fun/interesting ever, Chrysler says this:
There are no unique restrictions for the use of B5. Use of blends greater than 20% is not approved. Use of blends greater than 20% can result in engine damage. Such damage is not covered by the New Vehicle Limited Warranty.
Whether this is a real problem or not is a separate issue, but owners should at least be aware of what the manual states.

Thanks Roadkill I'm new to the diesel so I'm trying to learn as much as I can!

Re: Biodiesel Blends

In the past I've heard that some manufacturers wouldn't approve higher biodiesel blends because they hadn't tested them enough and because they didn't think there were good enough standards for exactly what would come out of the biodiesel pumps.

I wouldn't be surprised if they're being extra-cautious in the US after seeing the wild variations that people have found in our ethanol gasoline blends that are all labeled "up to 10%".

Re: Biodiesel Blends

Here in Illinois, where corrupt politian's rule, the state has mandated B20. Nothing against farmers, but to mandate that fuel contains 20% Biodiesel, seems a little big brother-ish. I cannot find B5.

Minnesota is mandating B10 during summer months this year and B20 starting in 2015. We go back to B5 during the winter. Is this a way to boost soybean prices like they did for corn prices with ethanol?

The "line" is that it reduces our dependence on foreign oil. Which I am sure is partly the case. It also ensures the continued development of alternative fuels. Farmers do get a benefit of knowing the have a market for their crops. The drawback is (still) that the mandates went through prior to the auto industry being ready. I understand the auto industry probably draged their feet, but to not even allow B5 (or less) be available is ridiculous. Full diesel should be available, at a slightly increased cost.

Meh. The counterpoint is that indirectly mandating that arable land be used to grow food crops that are diverted to inefficiently produce alternative fuels causes massive distortions in the market and drives up the cost of food everywhere.

Call me when they are using something efficient like algae to produce biodiesel rather than simply diverting tax and food dollars to Monsanto's bottom line.

Re: Biodiesel Blends

Here's an idea to cut off the dependence on foreign oil - drill at home.


And F big brother and all of the market manipulation including this.
