I have a question about an oil change issue on a 20 kw home unit.

Call wrink, he knows oil


What's the question? Not a Generac tech per say, but I have maintained my inlaws 20kw Unit

i have a 13k unit,it uses mobil 1 0w20.

I've installed quite a few. What's the question?

The first 2 oil changes the oil was clean.The third oil change oil was a color like coffee.Do I have a problem ?

Any particular smell?
I am assuming you are air cooled?
Generally generac is responsive, make sure you let them know what is going on within the warranty period. They typically work well on warranty issues when using a certified dealer.

Thanks !

Why don't you call Generac,

I did call them when I saw the problem,but they were not helpful.

Sy I see you live in a cold area! what i have seen is if you have the Gen setup to run lets say Bi-monthly for 5 min to exercise the unit the moisture does not have enough time to burn offf and can turn the oil color and not necessarily milky.
