Check and Top Up Engine Oil Regularly

Engine oil is the lifeblood of your generator — it lubricates moving components, reduces friction, and carries away heat. After shutting down the unit, wait a few minutes for oil to drain back into the crankcase, then pull the dipstick to verify the level. Top up as needed and stick to the manufacturer-recommended drain interval for both oil and filter replacement. Always use lubricants that meet OEM specifications — not just any diesel oil will do. For ZTA-supplied sets, refer to the manual we provide with each unit for the exact grade and service-hour schedule.
