Atleast till 12kva. Above that you need a more presure in the Gas line which needs a bigger meter or something like that for that you have to request.
@poster, They recomend that a Generator go up to 80-100 hours on 1 oil change, But for me i change oil every 15-20 days (3 hours daily makes it 45 hours aprox) i usualy go for the oil that is saved from my car other then that Shell (red) /Caltex (10-30)/Total 1 liter can. im not sure about Total grading.
