cetane rating?

[atk]

been buying bio-diesel for the last few months. it first started out at B5 then went to B10. i lately found out that it has been upped to B20, but will going back down to B10 for the winter months...so my question is, is it possible for it to have a 65 cetane rating?.... ..... i finally called the company and that is what they told me. so do i believe them?....

Sounds too high for straight B20. Maybe they got the number transposed or something.

Here's an article on biodiesel that talks about cetane.

alex, that does seem high.

perhaps call for a second opinion..
