this generator was fired up during the ice storms in arkansas, and ran continuously for 312 hours. it had gone into storage with some gas left in it, and it required both some choke and some seafoam to run (idle circuit clogged). considering the MFG OCI is 50 hours, i am VERY happy with this oil. i figured it would be toast. vis drop is probably from fuel dilution considering it was being run with the choke the whole time. i put in a couple of universal averages in (), which are for 125hrs
