  1 Question
Q: On a 14kw generator should I use the regular oil or the syntheic oil which would recommend. Does the generator keep the battery charged.
by Mike Zimmer from New Jersey on March 15, 2013

A: In the owner's manual on page 23-24 there is an oil chart and based on the temperature in your local area would determine which oil type to use.

Owner's Manual

The generator has a built in battery charger inside of the controller and when properly connected it will maintain the battery.

Great Kit
If you just spent a good chunk of cash on a standby generator and want it to work when needed, this once a year OEM maintenance kit is worth every penny....

Generac generators are very easy to maintain....Once a year (or less than 100 hours) I change the oil, swap out the plugs and change the air filter, check the battery or change the battery every 3 years...

An ounce of prevention is worth a pound of cure... Take care of your generator , it will take care of you and your family or... more

Worked Great
Mad my generator for 7 years. I runs once a week, I've only had power lost twice but worked great, I'd buy it again.

Complete Peace Of Mind
After losing our power for 13 days because of Superstorm Sandy, we vowed never to let that happen again. When we rebuilt there was no question that we would add a whole-house generator. The question was where would we get it? Our electrician strongly suggested Electric Generators Direct, and he was absolutely correct.

They answered all of our questions both through e-mail and on the phone, and always took as much time as necessary to make sure we understood the answers. We got exactly the... more

Easy Way To Keep Your System Working!
I like to install a new kit every year to make sure my generator will do the job when needed. I change the oil when I install the kit also. I like the kits because they have all you need to keep your unit running like new.

Maintenance Kit
I have a Generac 13kW Home Standby Generator. When I first purchase it and had the first annually maintenance done, I was charged $216 dollars. After that I went online and found Electric Generators Direct and ordered my maintenance kit and started doing my own maintenance. And the kits wasn't that expensive to purchase. So it beats having the company I had to install and do annual maintenance, and much cheaper.
Pros: I'd Buy It Again, Easy To Use, Features, Price
