3408E (7PR) And 3412E (4CR) Industrial Engines Caterpillar recommends the use of multigrade Caterpillar Diesel Engine Oil (DEO). Caterpillar oils are formulated to provide Caterpillar diesel engines maximum life and performance.
Multigrade Caterpillar DEO meets or exceeds the performance requirements of the American Petroleum Institute (API) CG-4 and CF-4 categories. * CG-4 oils are designed to operate in the latest low emissions, direct injected (DI) engines and are especially effective in controlling soot and wear.* CG-4 oils are the first API oils to place limits on viscosity loss.* CG-4 and CF-4 oils are able to withstand high piston temperature to control piston deposits.* CG-4 and CF-4 oils were tested with both low sulfur and standard diesel fuels.
Multigrade Caterpillar DEO is available at Caterpillar Dealers around the world. If multigrade Caterpillar DEO is not available, use ONLY the following commercial oils: * Preferred Oils - API CG-4 is the preferred classification of commercial oil.* Allowed Oils - API CF-4 is also allowed.
Engine efficiency and performance depend on the use of recommended lubricating oils and adherence to proper operation and maintenance recommendations. Failure to follow these recommendations may result in shortened engine life.
