Portable FAQ's

Where is the engine made?
The engines used on the Generac XP and XG Series of portables are manufactured at our Generac Power Systems, Inc. factory in Whitewater, WI.  Generac engines are industrial grade engines designed to provide the ultra-quiet, longer-lasting performance required of portable generators.  Generac OHVI industrial engines run three to five times longer than competitive SV/OHV lawn mower style engines.
What is the difference between rated watts and maximum (surge) watts?
Rated watts describe the amount of power the portable generator can produce continuously.  Maximum wattage is the power that the generator can produce for short periods of time.  Motor starting is a good example of maximum wattage requirements.
What type of oil is recommended? How often should it be changed?
Above 40 F, use SAE 30. Below 40 F and down to 10 F, use 10W-30.  Below 10 F, use synthetic 5W-30.  Oil should be changed after the first 8 hours of operation and every 100 hours of run time thereafter.
What type of gasoline is recommended?
Use clean, fresh unleaded gasoline with a minimum 85 octane rating. Do  not use any gasoline with more than 10% added ethanol.  Never use E85 gasoline.  Do not mix oil with gasoline.
How often should I perform routine maintenance?
The maintenance schedule for your portable generator is in the owner's manual.
Does the portable generator need to be grounded?
Yes.  For safety, the generator must be properly grounded.  If it's not grounded, you run the risk of electrocution.  We strongly recommend that you check and adhere to all applicable federal, state and local regulations relating to grounding.
Should the fuel be drained when storing the portable generator for more than 30 days?
Yes. It is highly recommended that you drain the fuel from the tank and run the carburetor dry. OHVI engines meet EPA and CARB regulations and are less tolerant of stale fuel.
Can I vent the exhaust out of an enclosed area?
No.  Never run the generator in the home or an enclosed area.  Portable generators are designed to run outside where there is plenty of ventilation.
Can the generator be used during inclement weather?
Generators can be used during a wide variety of weather temperatures, but should be protected from the elements when not in use to prevent shorting and rusting.  NEVER run a generator indoors.
