Prefect size Generator for my 2400 sq ft. home. Runs the well pump, all lights, computers, TV's, 2 Refrigerators and more. I like the smaller engine because it is easy on gas, an important consideration for extended power outages. This unit took 1.5 qts 10-30w motor oil. I drained the oil after 8 hrs to get the metal shavings out of the new engine, then replaced the oil with synthetic 10-30w Mobil 1. This reduced the noise level and vibration considerably. Very well built for the price. Super Happy!
