Technical Service Bulletin 06-1 The Effects of Biodiesel on Fuel Filters Biodiesel, n. – a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM D 6751. Biodiesel blend, n. – a blend of biodiesel meeting ASTM D 6751 with petroleum-based diesel fuel designated BXX, where XX is the volume percent of biodiesel. Overview Biodiesel is an alternative fuel that is rapidly growing in use. However, biodiesel received a bad reputation after the problems that occurred 2005 when some states mandated the use of B2 biodiesel blend statewide. One of the problems was very short fuel filter life. Further research revealed that the problems encountered were not due to the use of the biodiesel blend, but rather the use of biodiesel that did not meet the ASTM D 6751 specifications. The use of biodiesel that does not meet specifications may cause problems within the fuel system. One false perception of biodiesel is that it can be made by simply mixing raw vegetable oil or waste vegetable with diesel fuel. Due to the high glycerin content in vegetable oil, these feed stocks must be refined and catalyzed to make biodiesel that meets the ASTM D 6751 specification. Filter Plugging Biodiesel has some solvent properties and will act as a solvent in the fuel. Blends greater than B20 may have enough of a solvent effect to break down the varnish deposits on the walls of the existing fuel storage tanks or fuel systems. The break-down of these varnish deposits will contaminate the fuel with particulate, which can cause fuel filters to plug rapidly. Once the contaminant is removed from the fuel, subsequent fuel filter service intervals should return to normal. Biodiesel blends up to B20 should have minimal solvent effects on existing fuel systems and blends below B5 should have no solvent effect above that of regular diesel fuel meeting ASTM D 975 specification. Blends of B5 and below should also meet the ASTM D 975 specifications for diesel fuel. Filter plugging problems can be prevented by effectively cleaning storage tanks before introducing biodiesel. Filter plugging can also be minimized by using low blends of biodiesel and/or ensuring the biodiesel that you are using is from a April 2006 Page 2 of 2 quality source meeting the ASTM D 6751 specifications. BQ9000 is a quality certification that certifies biodiesel suppliers that provide quality biodiesel meeting the ASTM D 6751 specification. Filter Compatibility Most fuel filters currently used in petro-diesel applications are compatible with bio-diesel blends up to B20. Check with your filter manufacturer for verification. Using High Blends of Biodiesel Filters that are used in special applications using high blends of biodiesel, those near B100 or unblended B100, should use solvent resistant sealing materials. Continued use of standard sealing materials commonly found on most popular fuel filters may result in deterioration or swelling of the material, which may cause leaks.

so if you use upwards of B20 you may have to change your filter after the first couple tanks (depending)...then you should be ok for regular filter intervals. and less than b5 no affects on the filter life. the study for lubricity used B2 and it kicked everything elses booty. don't know if anyone has ever done a study on wether or not BD helps improve the BTU properties of ULSD but it sure seems to be a good lube.
can anyone confirm MPG efficiency using B20 or less mixes?

I use B20 in the summer months, as it is removed fom the pumps from roughly October till April/May and replaced with B5. Here in Mid-Michigan the cold could affect the usability of B20. It usually runs about the same price as petro. maybe a few cents more. I get maybe 1-2mpg better and it is quieter. I have noticed the milage increase is more noticable in city driving than highway driving, and have noticed no noticable difference in power. You can make your own biodiesel for about 75 cent per gal. from what I have read, but depends on getting the waste oil for free. With the popularity of home brewing rising, I can see resturants starting to charge for it. Everyone needs to make a dollar.

I dont know a whole lot about bio diesel. Right now im stickin to just reg diesel. i have had some people tell me not to use any bio diesel cause it will jack up my truck. but then i hear alot of people that swear by used vegetable oil. any body had any problems with their trucks after runnin bio diesel for awhile?

What's your average temps (day/night) for the 50/50 mix, and what temps do you call "colder?"

I ran biodiesel in my 04 2500 CTD. I ran 50/50 bio and diesel. WHen I first started using it, on cold mornings my truck had a hard time starting, but once I change the fuel filter it ran great! I would recommend it especially since the diesel price just went over $4.00 a gallon in Tx. The last time
I bought bio it was about $1.75 a gallon!

I've been running B20 in my truck since September of 07. I have dropped the tank twice since then, and both time it was clean enough to eat out of. Never had any filter problems. Still use the same filter I get from the local parts store and change it every other oil change. I get better MPG and truck runs quieter. I even tow my 30ft horse trailer with it. The cost is usually right at the same as D2 or a little less. It is certainly cheaper than buying an additive to put in the tank.
