Just be prepared to change fuel filter more often until everything is cleaned out.

It has excellent lubricity and will keep the system cleaner. Full bio is another story and has more precautions, but most things do well with 5%-10% bio.

After a tank or three, you might be surprised at the difference it might make

The new engines run a lot hotter than previous models which will break the oil down. Ever wonder why they don't install Pryo gauges anymore. The cost of a $250 oil change is alot cheaper than a $25,000 engine.
they don't install pyro gauges on fleet trucks anymore for the same reason they do not install most other gauges in them. the union drivers shut down and call for road service if the gauges do not point up and down. so to prevent this and save thousands of dollars, a kyser system is installed and the only gauges in the trucks are speedo, tach, and fuel gauge. if it runs, you run it, and don't call for service until the kyser system shuts the engine off.

we have a brand new kenworth that is loaded with gauges, including the pyrometer.

as per manufacturers, no fuel additives at all.
like SMT said, additives end up costing you thousands of dollars for a new fuel injection system.
clean fuel is all you need.

there is no way i would ever put anything except for clean diesel fuel in the tanks of a $203,000 truck.

Biodiesel in small amount isn't considered an additive. 5% or below doesn't even require labeling at pumps.

Here's some info. Lots out there, but this is just a little bit.

Alternative Fuels Data Center: Biodiesel Blends

Biodiesel and warranties:

http://biodiesel.org/docs/default-so...).pdf?sfvrsn=6

Excerpt:
Most OEM dealers and customer service departments currently tell their customers the use of up to 5% biodiesel (B5) is acceptable, with the requirement the pure biodiesel fuel adhere to the quality standards specified by American Society of Testing and Materials standard (ASTM D 6751) prior to blending. Many OEM’s are also recommending biodiesel and biodiesel blends only be purchased from BQ-9000 certified companies. There are some OEM’s who tell their customers biodiesel blends up to B20 are acceptable, while others say anything up to B100 is acceptable.
Some of the B20 Fleet Evaluation Team Members from the above document:

B20 Fleet Evaluation Team Members
Cummins, John Deere, International Truck and Engine Corp, DaimlerChrysler, Caterpillar, Ford Motor Company, General Motors, Department of Defense, Siemens, Delphi Automotive Systems, Volkswagen, Engine Manufacturers Association, MARC-IV Consulting, ASG Renaissance, Bosch, FleetGuard, NREL, BMW of North America, Mack Trucks, Stanadyne Automotive Corporation, Suncor, CNH Global, Parker-Hannifin-Racor Division, and DENSO International America.
Biodiesel Facts vs Myths (see attached pdf)


Some more info:

Biodiesel-Ready Cummins Engines - Cummins Engines

Excerpt:
What Cummins engines can be used with B20 biodiesel?

The current approved engine models are as follows:
On-Highway: ISX, ISM, ISL and ISB engines certified to EPA ’02 and later emissions standards, ISL, and ISB engines certified to Euro 3.
Off-Highway: QSX, QSM, QSL, QSC, QSB6.7, QSB4.5 and QSB3.3 engines certified to Tier 3/Stage IIIA, QSM Marine, QSM G-Drive.
High Horsepower Off-Highway built after January 1, 2008: QSK78, QSK60, QSK50, K2000E, K50, QSK45, QSK38, K1500E, K38, QST30, QSK23, QSK19 and K19. Also Marine QSK60, QSK50, K50 QSK45, QSK38, K38 QSK19, K19.
Cummins has approved B20 for the high horsepower engines listed above with the following fuel systems: Pressure Timed, High-Pressure Injection, Modular Common Rail Fuel Injection System and BOSCH Pump-Line-Nozzle.

Whether or not you (knowingly) use biodiesel is your own choice, but it isn't like some of the snakeoils out there sold as additives It doesn't like cold, though, and I don't know of a "great" biodiesel additive to prevent gelling and such. You can cold filter and such, but that wastes a bunch.




The default answer if you are unsure is "Check with the manufacturer"

well i really don't have to worry too much about that, because i have never seen bio diesel anywhere here except for one place that went bankrupt after realizing the stuff would not pump or work at sub freezing temps.

The government is really good at taking something that works perfectly fine, and screwing it all up. That's progress, right ? Hm.

Ouch! Yeah, when I was making biodiesel a few years back, I switched to kero-cut dino diesel every fall and back in Spring.
