Information:
Dealer S.O.S. Lab Information:
The SOS Infrared Analysis limit for Allowable Soot is 100% and should be used for all oils. If Caterpillar-brand DEO CF-4 oil is used, then a maximum limit of 130% soot can be used for the 950F. This 130% allowable soot limit does NOT apply to other brands of CF-4 oil because the level of soot dispersent additives in other brands of oil is unknown and varies considerably. Of course, other oil conditions such as wear metal content, "dirt", oxidation, fuel dilution, etc. should also be monitored.
Customer Information
Advise Customers and maintenance personnel of the following information:
These engine updates are intended to reduce 950F engine oil sooting/sludging during the recommended 250 hour engine oil/filter change interval.
1. After this Update, the oil refill is 31 Liters (8.25 U.S. Gallons, or 7.0 Imperial Gallons) due to the new larger engine oil pan and new oil level gauge (dipstick) which raises the liquid level slightly. The former engine oil refill capacity was 20 Liters (5.2 U.S. Gallons, 4.4 Imperial Gallons). Failure to install the new larger quantity of oil may result in oil starvation and engine damage. Customers should inform their maintenance personnel of the new larger Engine Crankcase capacity.2. The recommended engine oil/filter change interval is 250 hours, and should NOT be exceeded, even with the new larger oil capacity. The recommended oil is API Specification CF-4, which has more dispersant additives than either CE or CD oils. If Caterpillar-brand oil is used, be sure to use DEO CF-4 instead of DEO CD.3. If an oil other than API Specification CF-4 is used, such as CD, or CCMC-D4 in Europe, then the engine oil/filter change interval should be shortened. Monitor oil condition with Scheduled Oil Sampling (S-O-S), including Infrared analysis to determine soot level, and establish an acceptable oil/filter change interval.4. Applications at altitudes over 1525 M (5000 feet) may need to use somewhat shorter engine oil/filter intervals. Caterpillar recommends the use of S-O-S, including infrared analysis, to monitor engine oil condition, including soot. The recommendations concerning shorter engine oil and filter change intervals when using of high-sulphur fuel have not changed.5. For machines which have been experiencing excessive sooting or sludging of the engine oil, Caterpillar recommends that customers temporarily shorten the engine oil and filter change interval to approximately 100 hours for the next 300 hours of operation to allow the fresh engine oil to loosen & dissolve any existing soot deposits that may still be inside the engine. Then, return to the recommended oil and filter change interval of 250 hours (also see items 3 and 4 above).
