Hey Psyphy....read the first 20 or so posts of the " Diesel Fuel Additive for 2013 Touareg V6 TDI" thread in the TDI section for some clarity. Biodiesel and it's benefits are discussed a lot there. In short, 2% biodiesel is sufficient. And there are a lot more past discussions on here about the use of biodiesel. Use the search function for biodiesel.

 

Thanks. I'll check it out.

I would stay far far away from any blend above the recommended B5. B20 only if you're in one of the states that mandates it and which VW issued a waiver.

Nothing above B20 under any circumstances.

 

Thanks. That's helpful. I still don't know if I get it, but pragmatically, I'll go with the program.

Note that there's no B20 waiver from VW if the vehicle isn't titled in one of the states that mandate B20. These modern clean diesels are very picky about their fuel and can't run any old biodiesel like older diesels could.

 

Thanks again. Great info.

 

Thanks all. A fellow Pgh'er on TDI forum set me straight. The station I would use is B5, so I can save the 70 cents & not void the warranty. Good to know the concerns RE higher concentrations. Interesting the MB has pulled their diesels out of Illinois.

 

On the same topic, I'm looking to start mixing a bit of BD in with the ULSD here in PA. About 15 minutes from my house, there's a station that sells B10 and right down the street, a Shell with ULSD. No idea how this mixing ratio works.

What proportion of the B10 should I be mixing in when filling to get around a B2 mixture? I figure I can stop, fill up with however much B10 I'll need, then go down the street and top off at the Shell.

Thanks for any help!

Just run the B10. VWoA is sending out notices that it is ok since some states are only doing B10. I have run full tanks of B5 in mine and it actually gets better mileage on Bio I have noticed.

 

If B5 is 5% biodiesel to 95% Dino diesel, and B10 is 10% biodiesel.....and B2 is2% biodiesel.... Just do the math.

 

Disregard, nothing to see here...

 

I thought that one might be a little off.

 

M Diddy......your going about it all wrong....you gotta use metric units to figure it out

 

Ok, I think I got it.

Say, for math's sake, we have a 25 gallon tank to make things even.

5 gallons of B10 would give me 1/2 gallon of BD + 4.5 gallons of Dino.

Adding on another 20 gallons of Dino diesel on top of that would then give me a 1/50 mixture of BD and Dino, rounding to about a B2.

Is my math correct here?

 

PS - I suck at math. :-k

 

I get my B100 at the Strasburg WoGo and they have B20

 

M Diddy, I typically get my fuel at the Pacific Pride in Plowville. I know it's fresh fuel as they use it on all their trucks and buses.
There's no requirement to label diesel which is why no pumps show biodiesel content or cetane rating.

 

John,

Had no idea there was a Pac Pride in Plowville. I actually go up 176 to work (in Exton) so that's on my way to and back.

Do they have BD there? Or straight dino?

Thanks for the tip!

 

Just straight diesel which of course is B2 given the PA mandate. It's off of Rt 10 where the school buses are. You need to apply for an account and can do that there in their office. They also carry off-road diesel which I use in my Kabota.

I worked in Lionville for many years but I took back roads there.

 

Just found out the AmeriGreen a 1/4 mile from my office in Exton has BD. Didn't see what it was, and it's not listed on Biodeisel.org, but it's there.

Not sure how fresh the gas is though. The station doesn't seem that busy so I'm sure it might be sitting there a while.

 

There was an Amerigreen in Morgantown that I believe has since closed. Their diesel pump was labeled B2
