B5 Diesel

Specifically, is there any reason not to put B5 diesel in a 2 year old Toyota Hilux Vigo ?

An excerpt from the PDF;

1. The use of B5 blends is generally accepted by all OEMs. Several biodiesel producers/suppliers in Australia claim that blends higher than 5% (B5) meet the diesel standard, and are therefore suitable across the diesel vehicle market. Further, diesel/biodiesel blends containing a low level of biodiesel up to 5% can provide some benefits to vehicle operation, in particular with lubricity when blended in low sulfur diesel.

However there are important chemical and physical differences between biodiesel and conventional diesel fuel.

The WWFC(l) identifies concerns from engine and vehicle manufacturers about introducing biodiesel into the marketplace especially at higher blend levels.

The concerns include:

• Biodiesel may be less stable than conventional diesel fuel, so precautions are needed to avoid problems linked to the presence of oxidation products in the fuel. Some fuel injection equipment data suggest such problems may be exacerbated when biodiesel is blended with ultra-low sulphur diesel fuels.

• Biodiesel requires special care at low temperatures to avoid an excessive rise in viscosity and loss of fluidity. Additives may be required to alleviate these problems.

• Being hygroscopic, biodiesel fuels require special handling to prevent high water content and the consequent risk of corrosion and microbial growth.

• Deposit formation in the fuel injection system may be higher with biodiesel blends than with conventional diesel fuel, so detergent additive treatments are advised.

• Biodiesel may negatively impact natural and nitrile rubber seals in fuel systems. Also, metals such as brass, bronze, copper, lead and zinc may oxidize from contact with biodiesel, thereby creating sediments. Transitioning from conventional diesel fuel to biodiesel blends may significantly increase tank sediments due to biodiesel’s higher polarity, and these sediments may plug fuel filters. Thus, fuel system parts must be specially chosen for their compatibility with biodiesel.

• Neat (100%) biodiesel fuel and high concentration biodiesel blends result in increased NOx exhaust emission levels.

• Biodiesel fuel that comes into contact with the vehicle’s shell may dissolve the paint coatings used to protect external surfaces.

I just came back from the Isuzu dealer because of car troubles. My car was stuttering a bit with rough idle.

They found out that I've been using B5 diesel and won't warranty my car.

They sucked out some fuel from the tank and it was really gunking and dirty.

They recommended that I clean out the tank and change the fuel filter after awhile and stop using B5 to not void the warranty. They said B5 cannot be used with commonrail DMax engines but direct injection are ok.

B5 diesel is supposedly less clean and more viscous than normal high speed diesel.

Ford (main dealer) specifically said B5 is OK in the Duratorq 3.0 TDi common rail (2006 Ranger) the missus asked at the last service, no warranty issues.

The older indirect-injection engines are much more tolerant of weird fuels. The old chap who collects our waste cooking oil bungs it in his ancient Nissan pickup (mixed 50-50 with regular diesel), seems to run OK, exhaust smells of fried fish
