Biodiesel and Volvo Penta Marine engine
Our local fuel dock now offers 100% biodiesel fuel. I am wondering if I
would run into any problems using this in a Volvo Penta Diesel circa 1989? I am aware that I will need to clean the fuel filter once the biodiesel dissolves some of the "gunk" left by the regular diesel fuel. Any thoughts/comments will be most appreciated. cvj |

Biodiesel and Volvo Penta Marine engine
I looked into this because I though it would be nice to be have the
smell of peanuts or French fries in a following wind instead of city bus. I was told, I'm not sure how authoritatively, that the biodiesel will cause problems for rubber parts. I tried to find out how many of those there are in my fuel system but couldn't. Later, when we were getting the engine degunked after sitting for six years with fuel in it and in the tank (things brokers don't tell you), we found that the fuel pump diaphragm had dissolved into mush. It looks like rubber. If regular diesel would do that to it over time, I suspect that it's something you would want to investigate carefully before using biodiesel. -- Roger Long "cvj" wrote in message news Our local fuel dock now offers 100% biodiesel fuel.

It may cause problems with rubber parts, but usually these are between the fuel tank and the engine, not in/on the engine itself.

Also, biodiesel is generally not as stable as petrodiesel, which could be a concern if you leave fuel in your tanks for months. Check with your supplier about this. There's a wide range among available fuels. Some meets mil-spec stability requirements, other stuff is a big question mark. If you go through fuel pretty quickly and don't leave it sitting in your tanks for months, this shouldn't be a problem. Other than that, biodiesel is a lot cleaner, smells better, cleans your engine, and has better lubricity. You can get lubricity benefits with as little as 2% mix (B2). Matt O. |

After some more checking I found that you should NOT use biodiesel in a boat
(like ours) that is equipped with an ESPAR boat heater. According to the ESPAR dealer, using biodiesel fuel will "gum up" the heater... :-) So with that info as well as the below replies to my post, I am staying with standard diesel fuel...
