Engine - Using Low-Quality Engine Oil
SOURCE: Mitsubishi Tech Talk Article January/February 2005TITLE: Using Low-Quality Engine Oil
APPLIES TO: All Models
SERVICE TIP:
It is very important that ONLY the recommended API SJ, API SL, or API SM engine oil be used in Mitsubishi vehicles. Lower quality engine oils can seriously damage engine components (excessive deposits, sludging, higher than normal component wear). Increased wear and deposits can also lead to excessive emissions.
Customers should be instructed to use ONLY engine oil which meets the manufacturer's requirements. Warranty coverage could be denied for failures attributed to improper engine oil usage.
