Most of those kind of hour meters quit flashing after one hour's operation. I have an hour meter on my Craftsman walk-behind lawnmower that has the Honda 160 engine. I got it in 2000, and it presently has about 510 hours on it. I've always used Mobil 1 oil, changing it once a year or about every 60 hours. After 9 years and over 500 hours, it still goes the full year with absolutely no oil usage. I just changed it the other day, using M1 10W30 HM. It was still right on the full mark with the old oil, and it did not look bad.
My hour meter flashes every 25 hours suggesting an oil change. Considering my mower's age and fairly high hours, I am considering changing it every 25 hours in the future.
