Detroit Diesel 16V92 Usefull Information 
 This engine will have a model number that starts with 816, such as 8167-7301. The serial number will start 16VF, such as 16VF1234. If you do not know your model or serial number, check the engine block for these numbers. 
 General Information 
 The Detroit 16V92 is a two cycle engine with 16 cylinders, 10 main bearings, and a displacement of 24.14 liters. 
 This engine uses 14.5 gallons of coolant and up to 87 quarts of oil, with a minimum of 63 quarts of oil needed for safe operation. The turbo engine uses slightly less (see section below.) 
 Lubricating oil should be SAE viscosity of 40, or with an API classification of CF-2. Oil should not have more than 1% sulfated ash. High temperature operation, above 200 degrees F, requires a lubricating oil with a monograde of SAE grade 50. For low temperature operation (not including marine engines), in an environment of 25 degrees F or lower, SAE 30 or SAE 15W-40 may be used. Replace with monograde SAE 40 lubricant as soon as temperatures climb above 25 degrees F. 
 Oil should be changed every 6000 miles for stop and go conditions, up to every 15000 miles for highway use. For marine units, change the oil every 150 hours of operation.
