Diesel Fuels & Diesel Fuel Systems
Application and Installation Guide
Fuel Conservation Practices Fuel costs typically represent the single highest operating cost associated with any diesel engine application. This has promoted various fuel conservation practices that can usually be applied to all applications. •

Keep air cleaners clean. Use an air cleaner restriction indicator to avoid guessing at air cleaner condition.
Avoid fuel spillage. Do not overfill the fuel tank. Fuel expands when warm and may overflow, especially when tank is not designed correctly. Operate the engine with a good electrical system. One bad cell in a battery will overwork the alternator, consuming more engine horsepower and fuel. A poor electrical system can also lead to hard starting, which encourages excessive idling. Size the engine or generator set to the job. Engines operate more efficiently at relatively high load factors. Do not increase fuel settings to obtain more power. Make sure all air hoses and connections do not leak. Leaks keep the compressor working unnecessarily. Make sure the turbocharger is turning freely so that proper air-fuel ratio is maintained. A clean burning exhaust should indicate these items are functioning correctly. Operate the engine with a thermostat all year; cold engines consume more fuel and wear out more quickly.
