This week’s question comes from John in Arkansas.
John asks: “How often should I change my oil in my engine and the gearboxes.”
The answer depends on the engine manufacturer. Each manufacturer has a different interval for the engine oil change, so check with your manufacturer.
Most engine oil change intervals are between 25,000 and 30,000 miles. Gearbox and transmission oil change intervals are between 350,000 and 500,000 miles.
