Biodiesel in Houston

So there is a biodiesel place that sells B20 in Houston. I know the 6.7 can run it but I don't want to mess anything up. Is it cool to just fill up and go? I ask because its 3.19 a gal!!!

What should I or anyone else know who may have the same question?

I looked it up on Gas Buddy, it is off 610 and 45 and looked like (before you get to 45).

Looked, couldn't find it. Im in that area weekly. Might have to check it out.

Still wondering about using it though....any heads up would be appreciated.

Don't forget you need to be running 5W-40 (per Ford's Diesel Supplement) before you run B20. It dilutes the oil much more than petro diesel, so it constitutes severe service. (Not that that's a bad thing--I plan on running it after I get a few more thousand miles on my truck--but it's something to be aware of.)

In this case, would you be able to alternate between B20 and regular pump diesel and not have any problems? Seems like the lesser cost of the B20 might not be as advantageous as it seems...

The problem is Ford's design for the soot filter cleaning cycle. Other manufacturers use a dedicated fuel injector just in front of the filter to pump extra fuel into the exhaust to increase filter temps and clean the soot off the filter. Ford uses the existing injectors on the left bank to inject diesel during the exhaust stroke. This also works to add fuel to the exhaust system and increase exhaust system temps to clean the filter, but since there isn't an ignition event happening when they do this the rings aren't being pressed against the cylinder walls and some of that unburnt fuel makes it past the rings and into the crankcase. For some chemical reason that's beyond my expertise, biodiesel is more likely to get past the rings than petro diesel. This leads to fuel dilution of the oil, hence Ford's requirement that you use a 40-weight oil if you're going to use B20.

My 2007.5 Chevrolet Duramax cleaned its DPF using this method and Chevrolet has since moved to a dedicated ignition source to prevent furl dilution.

I did oil samples every 7,000 miles and never saw high levels of fuel in my oil. There was some, but the lab always said "continue service".
