Biodiesel Blends
 

What is the highest blend of Biodiesel that is safe to run in my 2005 6.0L? I'm going on a trip at Thankgiving, and would like to try a tank. The only blend that I can get my hands on is B11. Will I notice a difference?

Probably won't notice much of a difference. A couple of years ago I used B100--I built up to it and only noticed a problem once during the winter; I had some thickening/full-on gel in the filter. If the supply was better here in San Antonio, I'd use biodiesel every time I filled up.

If you notice a difference, change your fuel filters.

I forgot to mention that a buddy has run only biodiesel for the last few years in his Excursion. I have a 2005 f250 (the 6.0). No problems at all except what I mentioned above--I ran the biodiesel until the supplier wasn't open when they said they would be.

Check out the biodieesel forum here at FTE.

How do you know if there is biodiesel blend at the pump? I use Safeway fuel here in Washington, I heard they have B5 but could find nothing on the tank.

Anywhere I have found bio, it's labeled on the pump. B5, B20, etc.

nice, I can only get B5.

biodiesel will clean out your fuel system. most people complain that it stops up their fuel filters without knowing that its doing the system alot of good. just got to change filters more often initially and will eventually return to normal intervals. i might would change the fuel filter before hand just to be safe.

And something else I forgot--older trucks with rubber fuel hoses will likely ruin the hoses. The newer (2004?) have silion hoses and will be fine--don't quote me on the year. But, 2005 is fine.

I run B2 in mine on every fill up. It is one of the best lubricants for your injectors. I have over 116,000 miles on the original injectors (hope I didn't jinx myself..lol) with no issues. Mobile 1 5w-40 every 5,000 miles too. I change the fuel filters around 12,000 miles and everytime they are very clean. If we had B11 readily available where I live that would be the fuel I would use on every fill up or at least mix it 50/50 with regular diesel to get 5%. Is there much of a price difference between the B11 and regular Diesel?

Have any of you read this thread? Just want to get your thoughts.

I have used B99 for the last two yrs. I general mix to about B50 in the winter months. Mixing is simple - fill the tank half way with B99, then top it off with dinodiesel. Only problems - you need to know the gel point of the biodiesel you are using and change your fuel filters regularly. Depending on the oil that the biodiesel is made from, it will have differing gel points - palm oil 60F, yellow tallow (chicken fat) 48F, corn oil 45F, rapeseed oil supposedly lower. I keep a mason jar with biodiesel in it outside next to my truck - if it is solid or looks like butter, then its time to switch to B50 (note - I live in FL). I have a large pdf on biodiesel that I'll try to find. Basically the only problem I have had was when I got caught with B99 in the tank on a cold morning. BTW, I just had the tank off for the harpoon - it is clean and no delamination (I think this is just a problem for the metal tanks). Also working on the fuel system when it is full of B99 is nice because there is no diesel smell and it cleans up much easier. I am sure there have been problems from home brews and straight vegi - I get a retail product that is used in all our municipal trucks at B20.

Other things - exhaust smells like burnt french fries, the truck starts a little sluggish but seems to run quieter and smoother, MPG drop by about 8%.
