Why Diesel Fuel Lab Testing in East Java Matters<\/h2>\n\n\n\n

East Java is a centre of industry and energy: the Tuban, Bojonegoro, and Cepu oil and gas area, the Gresik, Surabaya, Sidoarjo, Mojokerto, and Pasuruan industrial estates, large power plants on the north coast, the Tanjung Perak port, and the gas pipeline network with mini LNG and CNG facilities. All these facilities use diesel for gensets, boilers, heavy equipment, and fleets. Diesel fuel lab testing in East Java from the nearest laboratory means samples arrive sooner and decisions to accept or reject a delivery can be made faster.<\/p>\n\n\n\n
