Home generator oil type

[Popdart]

Hey guys . . . . I bought my Generac / Wheelhouse 5500 Watt portable generator used and it's time to change oil. Operator's manual does not specify what type of oil. I went on line without much help. I would think that generator engines are under much more abuse than other applications. Anyone know what to use or recommendations? My generator has operated flawlessly and I don't want to screw it up. Thanks, Rog

do you have an engine manual that came with it?

• Follow the oil grade recommendations and oil fill
instructions given in the engine owner’s manual

this is all i saw.. kinda crazy it isn't in the normal manual..


maybe look up the make and model of the engine and see what it says..

I put a straight 30 weight, non-detergent oil in mine when I changed it.....

Air cooled engine oil by Brigs & Straten is what I use in mine

Mine has a spin on oil filter and so I don't use a non detergent oil but I do use the same stuff I use in all my vehicles and that's Rotella. It's also a Generac but a 7000. Had it for years and it saved everything in my freezer and fridge when Ike came through.

Another good choice, I run Rotella in my 66 solid cam /6.

I downloaded the operators manual and it doesn't say anything. I have no engine manual Good idea researching the engine. Thanks

I run straight SAE30 in all small engines. I only use non-detergent in pre-70 tractors and small engines.

Thanks . . . kinda leaning that way . . . you are in Michigan too and I'm a geezer and concerned about hard starting . . . ;-). My generator usually starts on two pulls in the winter. Rog

This is what the manual for it called for.

I seen that recommendation on the Briggs site too. Concern I have is that I have lost power in both summer and winter. So my temp range is quite wide. I'm going with the 30 straight. Thanks

That's probably the safe way to go.
Your welcome!

I have some extra Amsoil synthetic 15w-40 diesel oil and have been using that in my smaller generators with no issues. I figure synthetics will hold up better in generators as well, especially being air cooled.

I put it in my oiled air compressor too!
