MotorOilHour play online

Oil replacement calculator for car engine. Gives motor-hours (not by mileage) for correct oil replacement.

Now city cars drive much smaller, staying in traffic jams. So the engine works much idling, without mileage rising. And the motor oil thermally degradates faster, and to be replaced much early than the mileage recommendation of car manufacturer.

This app is a calculation attempt of the working motor-hours of the engine basing on the used fuel amount, with no mileage taken into account.
Calculation is made for a chosen time period and the fuel amont used during this period. The hour fuel consumption is calculated and finally - the period of motor oil replacment.
If the calculation result is "to replace the oil in an year (52 weeks)" - it's recommended to follow car's manufacturer mileage interval.

Sure, it is not ideal calculation, no warranty to be correct - please, send your statistical info by email (real mealage results together with calculation result), to adjust the calculator.

The result output will be edited, maybe saved in a table for each entered period, according to your comments and requests.
