not sure if this the right spot for this but here goes. is it safe to run B100 in a crd libby? is there anything special you have to do to run it?

B100 is 100% biodiesel. If you have never used it before I would slowly increase the ratio of B100 to standard diesel. For example, top off with 5 gallons of B100.

Biodiesel acts as a solvent so it can clean out your system, but it should not be a problem with our newer CRDs. Older trucks with high mileage would most likely get clogged fuel filters if suddenly switched to B100.

Also, B100 gells up in cold temperatures, so it is not recommended in winter. Better to use a blend like B20 or B5 in winter if you live in cold climates.

Personally, I have used B20 or B5 95% of the time in my CRD and have had no fuel related issues.

I have not tried high B but stoutdog has with no problem other than a 10% or so drop in mpg. For B20 or lower there doesn't seem to be much mpg penalty.

Stoutdog if I am correct lives in Arizona and moved from San Diego, CA.

I would not want to go any higher than B-20 in the Northern Winter like I get in the Midwest.

If you buy it from the pump instead of brew your own (Hotels don't like me brewing it in the room ) like I do from time to time, keep your receipts, it will help your Lawyer get your rig fixed if you get a bad batch.

If I did brew my own, I would run it through a Centrifuge to clean up any contamination, cheap insurance.

Close... I live in AZ but I'm from Florida. Papaindigo = my father. Either way, I would definitely not recommend running B100 in a northern winter.

B100 will show you about a 10% drop in mpg. Locally, it currently costs about $0.50 less than regular diesel, so it's worth it. Unfortunately, the local ATSM certified biodiesel dealer no longer sells to individuals driving up to his shop, only in bulk. Something about industrial district zoning or some such... grrr.

I've run B100 three seasons now, over 50k miles, with no issues. Gelled once this winter during the cold snap with B30, so you definitely need to blend it for cold operation.

not sure what it costs but i dont think its cheap but i would try to use used fryer oil

Biodiesel has a much higher cetane rating that regular diesel and burns a good deal cleaner. Also a great lubricity additive, I personally don't trust the petroleum manufacturers to add the proper amount of additives to keep your injector pump and injectors happy. Bio is a good insurance policy. It's a good idea to keep spare filters in the vehicle as a general rule anyhow.
