Brochure Describing New Diesel Lube Oil Available From Mobil
A f o u r - p a g e , full-color brochure describing the benefits of a new engine oil for high output, marine diesel engines is available from Mobil Oil Corporation. Mobilgard 446, designed for use in General Motors Electro-Motive Division (EMD) engines, including those equipped with silver wrist pin bearings, also meets all EMD, GE Class II, Alco, Fairbanks Morse, and Detroit Diesel heavy-duty requirements. It also meets the API requirements of a CD oil for Caterpillar and Cummins turbocharged diesel engines.
This SAE 40 oil is also designed for these same type engines in drilling rigs and stationary power generation service.
The new oil is said to provide superior engine cleanliness and extended wear protection even w i t h f u e l s having sulfur contents up to 1 percent. It leaves no hard-carbon deposits in ports and rings.
Pictures in the brochure show results of tests of Mobilgard 446 in EMD-645 engines covering 13,- 500 to 20,000 hours of operation. Cylinder liners show virtually no wear, and were almost completely free from vertical scratch marks. Ports were free of hard carbon deposits. There were no silver wrist pin problems during the test. Approximately 70 percent of the original lead flashing remained on the bearing surfaces.
There was no feathering of bearing material into oil grooves, and oil grooves were free of deposits. For a free copy of the brochure,
