Generator blow-by

[jack14r]

I changed the oil in the Kohler generator before my last trip and ran it 79 hours last week.I don't know if this is normal for others but I have a small amount of blow-by that is on the floor below the generator,I had not noticed this before.I burned .85 of a gallon per hour average,and the weather was 65-90 degrees during the week.I don't think that anything is wrong but just checking if others notice the same small amount of blow-by as I have.The oil level on the stick might have moved down 1/16-1/8 of an inch so consumption I think is OK.Even though Joe does not like it I am using Rotella 15-50.

I've not seen it before, but I will give mine a good test the week of 7/27 when I intend to run it near continuously for 8 days at Oshkosh.

Did you mean 15W40?

[jack14r]

Yes,I meant 15-40.

Jon,I wonder if the newer gen's have a higher thermostat than the older ones for emission reasons,mine seems to open at about 180 degrees.

Jack,

My Marathon would put a little oil out the breather, so I made up a simple catch can out of a coke can and that kept the floor clean. Mine never used any oil and I only use Rotella because it's been proven by Acme Hydro-Carbons to be better than Delvac. Mine is old school compared to yours, but it runs dead on 180.

[Jon Wehrenberg]

That's where my generator runs also. The Kubota on my old coach would run around 160.

Thanks Truk and Jon for the responses,I also thought that I would make a catch can for the breather tube.
