Fuel Records

The Fuel tab keeps track of the fuel mileage for your vehicle.

LubeLogger supports fuel mileage calculation in the following formats:

• American Imperial (MPG)
• European/Asian Metric (L/100Km)
• British(Purchase Gas in Liters and calculate fuel mileage as Miles per Imperial UK Gallons)
• Electric Vehicles (mi./kWh or kWh/100Km)

Initial Fuel Up

In order to calculate fuel mileage, you must first have an initial fuel entry with the current odometer reading. An odometer reading is needed so that the app can calculate the distance traveled between fuel ups. It is recommended that you fill it up to full for the first entry.

Imperfect Fuel Ups

For the most accurate results it is recommended that you always fill your vehicle up to full and not miss any fuel ups, but sometimes things happen, which is why we provided the following:

Partial Fuel Ups

On the occassions that you cannot fill your vehicle up to full, you can defer the fuel mileage calculation by unchecking the "Is Filled To Full" switch. Doing this tells the app to defer fuel mileage calculation until the next Full Fill Up.

Missed Fuel Ups

Check this if you have missed a fuel up record prior to adding this fuel record. This effectively resets the fuel mileage calculation and will show up as $0 or "---" in the fuel records. Checking this ensures that the average fuel mileage calculation isn't skewed due to missed fuel ups.

Calculation of Average Fuel Mileage

Average MPG is calculated by excluding the initial and missed fuel ups, then taking the difference between the min and max odometer reading and dividing it by total amount of gas consumed(if Metric then it is further divided by 1/100). This method will include all of the gas consumed by full and partial fuel ups.
