    • very easy to use, and is able to use both LP gas and petrol.
Style: 7500-Watt Dual Fuel
This dual fuel Generac generator has been very effective in empowering my house when I lost power.My first use was early May and I lost power for three days and it ran very efficiently, gas consumption was relative needing about 10 gallons in the three days that it was in use. It’s very easy to start and hook up. It powered most of my appliances, including refrigerator, stove, microwave, fans,my water pump, and Boiler I would recommend this to anyone who needs a generator that can power your house when you lose electricity. ... show more

    • Dependable, and reliable
Style: 7500-Watt Dual Fuel
Easy to assemble and it started as it should and work through it out of the box. Have not used it yet for a storm, but I’m sure it will be good as we have another Generac generator and that one has worked flawlessly

    • Parts Missing
Style: 15500-Watt
I like the build quality. I'm currently breaking in the generator, runs great. Made in USA definitely a plus. Value for the money spent is good compared to overseas models. The issue is that the axle for the wheel kit is missing from the wheel kit box. You'd expect better quality checking before shipping. Currently have been on hold w/ Generac support 25 min. I got a very nice girl to help me with this issue, so we'll see how good the support is. I'm getting the axle @ N/C under warranty. The drag is the 7-10 business days for shipping because Generac doesn't expedite shipping. UPDATE: Generac did UPS me an axle kinda quick, so kudos to them for that. Generator is running fine so far for 10hrs on brake in, only glitch was having to reset spark plug gap to proper .030 as it started to sputter a little. Spark plugs are gapped wrong from factory @ .018. I'm a auto tech so not a big deal. So far I would recommend this unit. It is well built, not bad on fuel so far & I'm picky. Also I like the fact it has AVR instead of capacitor regulation. Better for electronics. ... show more
