Biodiesel impacts all diesel engines — no matter what brand and the cautions of using biodiesel.
- Through repeated exposure, biodiesel can seep through certain seals, gaskets, hoses, elastomers, glues, and plastics.
- This is more of a problem in older engines. 2002 and older. This will affect the Bosh VP-44 and CAPS injector pumps used on the ISB and ISC series engines.
- Now, the question is can the older style mechanical injection pumps be rebuilt in a way to decrease this affect and extend pump life?
- Natural rubber, nitrile, and butyl rubber are particularly vulnerable to degradation.
- Brass, bronze, copper, lead, tin, and zinc can accelerate the oxidation of biodiesel and create deposits in the engine.
- Compared to conventional petroleum diesel fuel, B20 will result in slight reductions in power and fuel economy. Expect a 2 percent reduction in power and a 3 percent reduction in fuel economy when using B20 biodiesel. Expect up to a 12 percent reduction in power and an 18 percent reduction in fuel economy when using B100.
- Biodiesel can accelerate the degradation of crankcase oil(results in changing oil and filters more frequently).
- When using biodiesel fuel, the engine oil level must be checked daily.
- In no instance should the fuel dilution of the oil be allowed to exceed 5 percent. OILSCAN™ can be used to verify fuel dilution levels.
- Fuel should be sampled periodically to ensure a consistent percentage of biodiesel.
- Biodiesel can reduce water separator efficiency.
- Biodiesel can cause cold weather flow degradation.
