Anyhting 95 up should be able to tolerate BioD. If you are unsure, then look at them at every oil change. If they look like they are getting wet on the outside or seeping, then its time to change them with some Vitron hose.
As for modifications needed for running Bio, no you dont need any, just carry a spare fuel filter and tools to change the filter for the first 6K after using bio. Also, dont be like some of the guys that start by using 100% bio and then wonder why their fuel filter clogged rather fast. DUH! Bio has a solvent like attribute to it, start with B20 for the first 2K then go to B50 (if available) until the fuel system stops clogging filters. If you have more than 100K, YOU WILL CLOG FILTERS! How long, I dont know, just carry a few spares.
After a few early filter changes, you should be good to go. And you will return to normal filter change intervals.
Now, some are going to chime in and say Bio is no good and they have had nothing but problems with clogged filters. Yes they did, but they didnt get past the cleaning of the system to reap the real benefits. #1 is not feeding those towel heads. #2 is feeding our American Farmer! #3 is a well lubricated, clean running engine that produces less emissions.
I have over 450K on my flatbed International, and over 200K are with BioD. Yes, I have had a fuel pump fail in that time, but it was the original pump from 95, and it died at 432K. My personal truck has over 50K on BioD, but I dont drive that as much since work sits in my driveway.
Hope this helps, and as CP said. Stay away from WVO, its just a plain bad idea.
