Gas pump octane guidance

A consumer concern that commonly arises at gas stations is the cost of fuel. Many automobile models recommend a particular octane (e.g., 91) or higher. However, the choice of fuel offers lower or higher-octane levels. Lower octane fuels cost less, but may cause engine trouble if used in some environments (e.g., knocking at temperature or elevation extremes).

A method is needed to offer automobile owners some guidance to determine whether the lower-grade fuel is sufficient. This could enable the consumer to save money.

The novel contribution is a program that makes recommendations of fuel grade for purchase. This can be in the form of a smart phone application or an onboard interface. Using relevant information such as external temperature or time of year, as well as input from the consumer regarding upcoming trip requirements and past driving and fueling history, the program recommends a higher or lower grade of fuel.

This system can be implemented on the pump side or through a portable computing device (e.g., phone, wearable computer, etc.). Implementation is identical for any device, except for data transfer. The requirement for high-octane fuel is primarily based on the high compression rate of some engines. The high-octane fuels do not detonate on compression as easily as low-octane fuels (knock). Based on this information, the system dynamically recommends or selects (in the pump-based implementation) the proper fuel for the vehicle.
