Operating Conditions for the Field Performance Evaluation
Duration - The minimum number of operating hours for a single engine installation is 7000 hours. The minimum for one engine at an installation with multiple engines is also 7000 hours.Load Factor - The load factor must be representative of the normal engine application at the site. High load factors are preferred.Lube Oil - The candidate oil must be selected by the oil company.The Cat Micro-Oxidation Test is recommended as a pre-screening method to qualify oils for Field Performance Evaluation.Note: Passing the Cat Micro-Oxidation Test does NOT guarantee passing the Field Performance Evaluation, but oils that do not pass the Cat Micro-Oxidation Test will likely fail the Field Performance Evaluation.Oil Analysis - Caterpillar recommends the S O S Services oil analysis program. Alternate oil analysis programs must measure oil condition and wear metals. Used oil samples must be obtained for analysis at 250 hour intervals.Oil Change Interval - The oil change interval is determined by condemning limits that are established by Caterpillar. The limits are based on analysis of the used oil and the trend lines that are established. Generally, the service life of lube oil for engines that use distillate fuel is between 600 and 1400 hours. Usually for engines that use heavy fuel oil, the service life of the lube oil ranges between 300 and 700 hours. If SOS oil analysis and other factors allow, maximum oil service life for diesel fueled engines is 3000 hours. Maximum oil service life for heavy fuel oil fueled engines is 2000 hours. Refer to the S O S article in this Special Publication.Fuel Analysis - An analysis of the fuel must be provided by an independent laboratory at the beginning of the Field Performance Evaluation. Subsequent analyses of the fuel must be provided at intervals of 2000 hours or provided when new shipments of fuel are received. The fuel must meet the guidelines that are listed in this Special Publication, "Fuel Specifications" topic.Criteria for the Evaluation
Oil Consumption - The oil consumption must not exceed two times the initial oil consumption during the 7000 hour period. The initial oil consumption is established during the first 3000 to 5000 hours of operation with the oil that is being evaluated.Final Inspection - At the end of the Field Performance Evaluation, these components from two cylinders must be removed and inspected: pistons, piston rings and cylinder liners. None of the following conditions are acceptable: sticking of the piston rings, scuffing of the piston rings or cylinder liners and excessive wear of the piston rings. Polishing of the cylinder liner bore must be confined to the area that is affected by the uppermost position of the top piston ring. The entire circumferences of the inlet valves and the exhaust valves must seal. Guttering of the valves is not acceptable.If a new engine is used for the Field Performance Evaluation, all of the cylinders in the engine must be inspected with a borescope. The cylinder that shows the worst
