[3] In visbreaking, a relatively mild thermal cracking operation is performed. A brand new engine should not use synthetic oils as they are too thin. [3] API FA-4 oils cannot be used in place of API CK-4, CJ-4, CI-4 and CH-4 oils. You can find links to relevant notices and more information about ExxonMobil’s privacy program here. And higher viscosity grades are preheated during use to bring their viscosity into the range suitable for fuel injection (8 to 27 cSt). [1] MDO is widely used by medium speed and medium/high speed marine diesel engines. Parker, CO 80134, Toll Free: 1-844-239-8101 Any oil is specified by two descriptions, its viscosity and its performance levels. Freight Info If the oil cooler isn’t working properly the oil will not be cooled to normal temperatures. Petroleum processors derive a number of different fuels from each barrel of crude oil. [2], The International Maritime Organization (IMO) develops regulations for marine shipping. JASO DH-2 is for heavy-duty diesel engines used in trucks and buses and JASO DL−1 is for passenger car diesel engine use. Later API Diesel Engine Oil Service Classifications, such as API CH-4, CI-4, CJ-4 and the recently introduced CK-4, were developed with a focus on the requirements of Exhaust Gas Recirculation (EGR), PDF and catalyst systems in engines introduced from the early 2000s. Standard oil should be used for the first 5,000 miles then a synthetic oil is fine to use. Gas Oil / Red Diesel. [2] But MDO does not need to be preheated before using. Volvo Operators Club, Help Centre This is a very common spot for oil leaks which are caused by a combustion of gas around the pistons. According to the a 2004 U.S. Diesel Fuel Sales statistics from U.S. Department of Energy, Energy Information Administration, Marine shipping only takes 3.7% of total diesel market. The dirty crankcase breather will cause gaskets and seals to crack and leak. We offer an assortment of synthetic and synthetic blend diesel engine oils. TDFL Finance & Leasing, International Parts For any engine, the appropriate viscosity to be used depends on lowest start-up temperature and highest ambient temperature experienced, and can usually be determined from the operator’s manual. The most common place for the diesel engine builder to look for leaks, on the outside of the engine, is crankshaft. [2], MDO is made from a catalytic cracking and visbreaking refinery. All website features may not be available based upon your cookie consent elections. Most large heavy duty diesel engines use SAE 10W30 oil. It is always best to follow the manufacturer guidelines for the type of oil used in a diesel engine. API CK-4, CJ-4, CI-4 and CH-4 oils may be used where lower classification oil (such as API CG-4) is recommended. Choose the appropriate viscosity grade for the range of operating temperatures that will be encountered, and there you are. GALLERY This is the temperature of the oil after directly passing through the oil cooler.The most common cause of excessive oil temperature is a blockage in the oil galleries in the oil cooler. If there are still no leaks you should inspect the crankcase breather. Some manufacturers specify a maximum Sulfated Ash/Sulfur/Phosphorus (SAPS) level in the engine oil. Some of the tests used in these JASO classifications are specific to Japanese diesel engines. [3] The catalytic cracking operation breaks large molecules into small molecules. Replacements & Returns, © Copyright 2020 TransDiesel Ltd. Caterpillar, Cummins, Detroit Diesel, Deutz, Mack, MAN, Mercedes Benz, MTU, Renault and Volvo are some of the diesel engine manufacturers who have developed their own OEM Diesel Engine Oil specifications. [2], ISO 8217 of the International Standards Organization (ISO) is the primary standard of MDO. From the chart above we can see that lower SAE “W” grades are specified for start-up at lower temperatures, and higher “non-W” grades are recommended for operation at higher ambient temperatures. BLOG CAREERS For the first time, a new API Service classification is neither interchangeable nor backward compatible with previous classifications. Whether you have a pickup truck or European car with a diesel engine, our oils provide the performance and protection to fit the need. [1] Those fuels result from a catalytic cracking and visbreaking refinery. [3], The market of MDO is much smaller than on-highway diesel. These are recommended for starting at lower temperatures and provide a slight fuel economy gain. Terms of Trade ENGINE REMANUFACTURING PROCESS, TECH SUPPORT Such engine oils are referred to as ‘low SAPS’. FAQ Our high-quality Mobil™ products are up to the task. The thin oil doesn’t give enough time for the gaskets, liners, rings and bearings to seat properly in a new engine. Due to its lower price compared to more refined fuel, MDO is favored particularly by shipping industry. MEPC has meetings periodically and discuss resolutions to current marine pollution by adding amendments to its official documents. First, look for any oil leakage at the seals at the end of the crankshaft.
