I've got two 9500s for whole house backup in parallel.

I've had several various models over the years.

These gennies have come a long ways since 2015 ... especially these newer quieter inverter models.

They are the best value on the market right now imho. I've got 8 hours on one and 12 on the other.

The key to these generators are proper breakin.

Here's the pro tip.

When you buy one the manual says 30 hrs breakin period then change the oil. That's some Chinese bullshite right there.

You do you first oil change at 4 hrs and your second at 8 hrs and your 3rd at 30 hours. Manual says 10w30. China is cold. I went with 10w40.

Here's the other secret. You go to Amazon and buy a $25 magnetic dipstick and a magnetic oil plug if you can find one. If not get a strong Neodymium magnet and attach it to the bottom of the oil pan between the dip stick and the drain plug.

Here's what you're going to find.

At the 4 hr mark there will be little pieces of metal. At the 8 hr mark there will be fewer pieces, tiny pieces, of metal stuck to those magnets. At the 30 hr mark you'll be free and clear to get on a normal routine maintenance schedule.

Also, only burn ethanol free gas in it and use some marine stabil in the tank.

I learned this lesson with a 3500 and a 5500 by a mechanic in our preppers circle.

Also, get a battery keeper connected to the starter battery if you're not going-to use it much but don't wait to break it in until you need it.

These are good generators.

Oh, and one other thing. When breaking it in try to keep it ln energy saver and don't stress it enough to get it up past 75%. You can increase that between 4 and 8 hours. Once you've got all the itsy bitsy pieces of metal out of the oil ... run that bitch hard and put'em up wet.

You're going to love these generators.
