Original Generac Oil
By Christine O
Texas
Purchased 07/13/2024 |
Review Posted 08/06/2024
This is a great deal considering some people are selling one quart on Amazon for $22.00 and up. We are set for the season and them some as after running 100 hours it needed 3/4 of a quart of oil. Even if you have a maintenance package you still have to check the oil after roughly 100 hours of running time. I feel more confident using original Generac oil even though they say you can use Mobile One. Package arrived in tact and on time.

Electric Generators Direct Review
By Charles F
Arkansas
Purchased 07/31/2023 |
Review Posted 09/12/2023
OK, the review is supposed to be for a case of Generac oil. Not a lot to say it's oil. I'm the type person that uses the manufacturer recommended oil.
My review is rated for Electric Generators Direct.They are a good company to do business with. Their web site is easy to use and their customer service actually answers the phone in a timely manner they are helpful and courteous. They are competitive in pricing. They have fast shipping, and it's the right product. Haven't had to return any items yet so I can't rate them on that part. I will continue to do business with them and I give them 5 stars.

Purchased 11/30/2020 |
Review Posted 12/22/2020
Great product. Great price. I can barely get M1 much cheaper then this Generac oil. Plus no worry about using car oil in the 20kw generator. Generac oil, so if anything goes wrong. I'm using they're stuff. At this price, why chance anything else?!? Also showed up very fast, even wife commented on how quick.

If you have a Generac Generator that requires 5w-30, I would highly recommend this oil as your only lubricant.

Product Questions
Answered by Ken, the eComfort Product Expert
I purchased a Generac generator from you a few months ago. The directions say that below 40 degrees, 10W-30 oil should be used. I presently have 30 weight oil in the generator. With the weather below 40 degrees, can I still leave the 30 weight in or is it best to actually drain it and replace it with 10W-30?

Is this the same oil that is included in the maintenance kits?
