Safety Tips

In an attempt to reduce the cost of flying, some operators have resorted to methods of operation which are considered to be unsafe. Lycoming makes the following recommendations regarding these practices:

1. Do not advance timing – set timing in accordance with the Engine Operator’s Manual for the specific engine model.
2. Do not use a hotter spark plug for low-power cruise – unless it is approved for the specific engine as listed in Lycoming Service Instruction No. 1042.
3. Do not abbreviate the warm-up of a turbocharged engine – follow the instructions of the manual pertaining to oil temperatures, otherwise an overboost or erratic power condition will result.
4. Do not use automotive oils in aircraft engines – they will cause engine damage or possible failure.
5. Do not use automotive fuel in aviation engines. Quality of automotive fuel varies widely and additives may result in deterioration of fuel system components. The engine manufacturers contend that use of auto fuel in an aircraft induces unnecessary risk.
