Charles, I've been burning approx 30% biodiesel: 70% home heating oil this past heating season. The only problems I've experienced are to be expected : Change line filter element and nozzle due to the cleansing action of BD on an old tank and fuel line. Learn how to do this yourself and have spare filters/nozzles on hand. I have a Beckett AF burner with a Suntec pump. The pump (and most others) has a rubber shaft seal which is incompatible w. BD. It will eventually swell and leak. I did not experience any problem with it for the 8 months I've used it w. BD30. My tank is in my basement and I did not preheat the mix even though temps go down to about 50F down there. This past week I have teed a small "experimental" tank into the fuel line and am attempting to run BD100 in the furnace. I replaced the Suntec pump w. a Webster Bio Pump (w. viton seals); very easy to do. So far: I've been able to run BD70 by adjusting the pressure screw on the pump (increase) and adjusting the air band on the burner (lowered). Knowing little about burners, furnaces, and pumps, and lacking pressure gauges, I limited myself to 1/2 turn on the pressure adjustment. A service tech is coming today from the local oil co. to see if he can get it going on BD100. Congratulations on your successful batch and best wishes, Tom ----- Original Message ----- From: "Charles List" <[EMAIL PROTECTED]> To: <Biofuel@sustainablelists.org> Sent: Tuesday, March 28, 2006 3:11 AM Subject: [Biofuel] Diesel heating

Also since it's just a combustion chamber, will I be able to get away with mixing some (20%?) WVO in with my biodiesel in my tank, and just cleaning my injectors each year? > Just also wanted to share my excitement at making my first 1l batch from WVO- processed well and the third wash is crystal clear!
