PETALING JAYA: Despite concerns over possible effects on engine performance, diesel vehicle owners are open to trying biodiesel if it offers significant savings at the pump.
Businessman Desmond Wong, who owns a diesel pick-up truck, said he is willing to try B15 biodiesel as a cleaner energy alternative to save on fuel costs, despite having some reservations.
“Although research shows it may have minimal adverse effects, an engine built for regular diesel may not completely avoid some impact from using biofuels.
“It remains to be seen. I am willing to try it, especially if it is cheaper than the hefty price of diesel I am paying now,” he said.
Negri Sembilan Lorry Operators Association treasurer Alvin Loke also said he is open to trying B15, although he is sceptical of claims that it will have no effect on the diesel engine fuel system.
He noted that many association members are still unfamiliar with biodiesel and how it works.
“Perhaps more information on biodiesel can be shared by the relevant authorities to help promote its use.
“Otherwise, people may be unaware and assume it is not suitable,” he said.
Tow truck operator Md Yusof Yahaya said he is cautious about using B15 biodiesel, adding that only long-term usage will reveal its actual impact.
“Naturally, we are a bit reluctant for fear it may affect the engine because this is something new to us.
“Repairs for diesel engines are more costly compared to petrol engines.
“I will cautiously still try and see how my tow truck engine behaves.
“If it is not favourable, I will just switch back to regular diesel,” he said.
Universiti Teknologi Malaysia’s Faculty of Science adjunct professor Datuk Omar Shawkatally said extensive local and international research has shown that biodiesel is safe for use in diesel engine vehicles.
Improvements in diesel engine technology are expected to further enhance compatibility with biodiesel in the near future, he said.
Omar noted that biodiesel is the way forward as it is more environmentally friendly and a sustainable alternative to fossil fuels.
“With the price of diesel soaring due to the global energy crisis, this is the way to go.
“What we need is renewable energy, not one that is heading towards depletion.
“Eventually, oil wells will run dry,” he said.
He added that converting bio-oils into biofuel will become easier as technology continues to advance.
A study by the US-based Society of Automobile Engineers International found that the use of B15 biodiesel maintained stable engine performance, power and torque.
The same study also revealed minor variations in fuel injection timing and in-cylinder pressure, with no significant operational issues observed during testing.
The research concluded that B15 demonstrated good compatibility with modern diesel engines.
