Been running it in the motorhome for three years, summers only, when it gets cold it goes in the barn. Two years in the pickup with no adverse effects in the pickup. On the motorhome the gasket on the fuel filter base will leak usally every spring but I change it every spring anyway so it is not a big issue. as far as O rings and seals if your vehicel is not over about 20 years old you should be fine. I bought a Fuelmiester about 3 1/2 yers ago and no problems so far. I did make a batch of soap early on, messed up a titration test asd did not have the catalyst mixed right but that was it. I did not want to do the appleseed type processor as I did not want build one.......Oh yea your stroke will love the Bio.....

Not a big deal at all to go back and forth. I dont have time either to make it all the time. I have yet to run it in the winter yet. Dont have the barn insulated and Im not going to freeze making bio!
I think B20 is safe enough for winter....no first hand knowledge though!

It dipped into the mid teens here last winter. I ran somewhere between B40-B50. Did just fine. There is a wide range of gel and cloud points with biodiesel, entirely dependent on your feedstock. I have had batches made with peanut oil cloud at 55F and gel at 42F. Whereas I have had soybean and canola oil cloud at 38F and gel at 25F. With each batch I make, I take a small sample jar, label it with date and feedstock, and leave outside. I look at these at ambient temperatures to guess how much #2 I will blend it with. Definitely not scientific, but it works for me.

B100
I have been making homebrew for a little over a year and a half with no problems. I recent bought an X 7.3l. I just put its first tank of b100. From what I understand, after 1995 or 96, all the fuel lines are either metal or a synthetic rubber called Viton(spelling?). Nither of which will be damanged from Bio. Carry an extra fuel filter with you because after the few tanks, your fuel filter will probaly get plugged. I have about $400 in my appleseed processor and have zero problems.
Happy brewing
