Aside from environmental benefits, is there any cetane benefit to a bio deisel blend???

My Dad and I used to have a Peugeot 504 Diesel that we used for commuting and we soon found it would run on kerosene, Jet 'A' and Home Heating Oil.

One of the most amazing things I ever experienced was running the engine on 100% Petroleum Based Cleaning Solvent. No knock, no smoke and a significant power increase.

I wouldn't think Wesson Oil would readily mix with Diesel, but I have never tried it.

Is there any audible change in the combustion process with a bio fuel???...Bert
