Unioil Euro Diesel IV

Last April, Unioil announced that it will soon make its entire fuel products comply with Euro 4 regulation. Well, that time has come as the independent petroleum company has officially launched its Euro Diesel IV brand of fuel, making it available at all of its service stations nationwide.

As early as February 2011, Unioil had been testing the Euro Diesel IV on a variety of vehicles, from an Isuzu-powered jeepney to a previous-generation Ford Ranger to a first-generation Chrysler 300C. Based on the tests conducted by the Department of Environment and Natural Resources' Environmental Management Bureau, the Euro Diesel IV showed a substantial decrease in harmful vehicle emissions across all test vehicles as compared with Euro 2-compliant diesel fuel.

It was the results of these successful tests that convinced Unioil to quietly bring to select service stations its Euro Diesel IV fuel by late 2011 before the petroleum company decided to launch it nationwide a year later today.

According to Unioil general manager Chito Medina-Cue Jr., besides the Philippines, only four other countries in the Asian region are still using Euro 2-rated fuels instead of Euro 4. These are Brunei, Malaysia, India and Pakistan.

"Other countries are already gearing toward cleaner and more advanced diesels," said Medina-Cue. "Here in the Philippines, we're just starting. We can't wait for 2016 when the DENR mandates that all fuels be of Euro 4 quality. We have to act now to save the environment, which is why we're making Euro Diesel IV available three years ahead of everyone else."

Medina-Cue added that, depending on the vehicle, the Euro Diesel IV fuel's sulfur content could be even lower than the 50 parts per million (ppm) as specified by the Euro 4 standard.

Other benefits promised by Unioil for vehicles that are running on Euro Diesel IV are: better fuel efficiency, thanks to the fuel's higher cetane number, which means it burns faster and has a better ignition quality; faster cold-start performance since the ignition delay is shorter compared with the usual diesel, even in low-pressure and low-temperature conditions of a long-idled engine; and a quieter engine since the diesel fuel is ignited before most of it is injected into the combustion chamber, resulting in reduced knock intensity and smoother, quieter engine operations.

The biggest benefit, however, is that despite the Euro Diesel IV being a superior product when pitted against other diesel fuels in the market, Unioil is "not passing on the additional quality cost to the public," which means its price is equivalent to that of the previous Euro 2-rated diesel fuel.
