Note regarding oil fill level at oil change:  Here’s the update from Kubota Engines.  The 722 generator on the GL11000 comes with either a 101mm or a 120mm deep oil pan. (4” or 4.75”). The 101 takes  .9 gallons of oil.  The 120 takes 1 gallon.  If the unit has the 4.75” deep oil pan it requires 1 gallon to fill it to the top mark on the dipstick. The GL11000-USA uses dip stick part #1G304-36410.

For the first 2 years or 2000 hours you must use factory filters, or you will void warranty. The owner’s manual recommends you change oil and oil filter first 50 hours. After that change the oil every 100 hours and the oil filter every 200 hours.
