bio-diesel

I believe the official Kubota policy supported B5 (5% bio) for warranty purposes. This is kind of rediculous. 5% doesn't seem worth the effort. I supppose they are doing it for CYA purposes.

I think it may because Kubota has not done its own tests with bio so for now they are not embracing it.
There are lots of published studies about engine wear - I read one about a comparison fuel test in city bus fleets. When the engines were taken apart for their scheduled 400,000 mile rebuild they found almost NO measurable wear in the biodiesel group, where the petro diesel group had normally expected ring and bearing wear. Here are some related links
I've used B100 and B20 for years - no adverse effects. The soybean B100 clouds the filter bowl (stops flowing) at around 20 degrees F.

rbargeron,

Just for curiosities sake, how much do you figure you are saving with bio?

Well, I started using it when petro diesel was a buck a gallon and pure soybean oil was $4.50 including truck freight. So I guess you'd say I was "donating" $3.50 a gallon to having a cleaner environment. Today I'm less generous to my neighbors and keep B20 in my barrel - about the same price at the pump as petro diesel - maybe 10 cents more.

Same thing with GM and the Duramax engines. GM states to use only 5% but there are many who use 100% BIO with no problems at all.

warning bio diesel eats the plastic in kubota's in line fuel filters, it reacts badly with the white plastic in the bx style fuel filters used on a lot of smaller machines. i know of a few people who change to another type of filter and they have so far had no other problems

maybe 10 cents more.

Why not get petro and save 10 cents then?

The claim is that biodiesel is less carcinogenic than petro. Not sure whether that's the fuel itself or the exhaust products or both. So I figure I'm throwing a scrap toward environmental responsibility and reduced dependence on the likes of Hugo Chavez.
