My first three tanks were petrodiesel, but since then I've been running B60-B70. I'm planning on filling the tank with B100 this weekend. It should be pretty close to B100, as my low fuel light is threatening to come on, and it's 80 miles to the pump from here.
Until there's a source for B100 closer to me, I'll probably stick to the B60-B70 blend ratio. I'd love to run B100 as often as the weather will allow, but I can only carry so much in the car.
I have run b100 up until December and run a b50 now. I wish I could afford to run b100 all the time, but figure 1/2 is better then none. I figure it still costs the same or less than my old gas burner did.
I bought my first batch of b100 3 weeks ago and have been running it in both my VW TDI's.. I'be been a little concerned since then when I read the threads about Bosch's concerns about biodiesel. Once the dust settles I'll decide whether to continue using it. Larry
B100 for the nine or so months we can and a B75 blend in the colder months. Over three years in the F250, 2.5 in one of the B4s and 1.5 in the other. The lawn tractor is an arromatic pleasure to pilot, and the neighbors love it too. Over 3K gallons and over 80K total combined miles logged on the precious liquid gold.
Say goodbye to Petroleum Madness, the Devil`s Tea is on it`s way out.
I must say that I am jealous of the ability to naturally use B100 all year long. Perhaps after I relocate to Maui?
The only mod I currently have on both cars is a coolant powered heat exchanger on the fuel filter. This allows operations of the B100 I make down to 21F. I would think that Atlanta would most likely be, and the Middle Gulf coast of Florida definately be outside of that range.
During the warmer months this heater serves to better atomize the fuel spray and keeps the viscocity of the fuel lower than the norm.
oops. Did I inadvertantly just knock off one of the main reasons for not using BD? As in viscocity? Oh well.
Wally do you have the racor coolant powered fuel heater? Those things are sweet. Especially the model with the built in thermostat option. A fuel heater would be nice for the b100 in the winter, but without the thermostat, I wouldn't want my fuel heater continuously working in the 100F summer weather we have here. I took a much cheaper route and got a top mounted heater for my FM100 filter.
I know this is off topic but I'm hoping this is the best group to answer this question, it appears all who have posted on this topic have alot of experience with BD.
So, I just finished a full tank of B100 (first time for BD) and the experience was good, quiet, no smoke, smells funky and about 42mpg city. BUT now it puts out larger clouds of smoke on hard acceleration than previous. Is this the norm after B100? I now have a full tank of diesel from my normal station. B100 is 2.40 gal here.
sure enough, others here have reported smoke after running a few tanks of B100 on a TDI with many miles on petro-Diesel. And here in western PA, some crappy diesel fuel can clogg TDI intakes as soon as 40k miles (this was one case seen by a VW tech).
Most likely, the B100 is loosening up the gunk in various places like the intake, and perhaps the bottom of the fuel tank, etc. A good thing to do is to replace the fuel filter after a tank or two of B100, in case some cleaning was done with the fuel tank. Other than that, step on it and run with biodiesel as much as possible (including blends).
BTW, I would bet that the intake in your TDI could have been somewhat clogged before you got it, because when I drove behind you this past spring I noticed that it would smoke each time you shifted gears. On the other hand, if you remember, I could really revv it up on our beetle and you wouldn't see any smoke out the back. Thanks to many miles on B100 or blends...
Mine smoked on hard acceleration, I've been running B100 for almost 5,000 miles. The problem wasn't biodiesel though. I have a 96 Passat with a 5th injector, which serves no earthly purpose (see the TDI FAQs). Disabled it, smoke gone.
Yes, B100 for 6 months now. Was paying $2.70, it went to $3 so we organized a bulk buy in Portland so we are down to $2.40/gallon, much better! There are about eight I know of running B100 in Portland.
B100 for the last 2 tanks. Mind you I only use it as a start and stop fuel - the rest of the time I am on veggie oil. My current tank of biodiesel has 3600 miles on it, projected to make it through July.
