This is the second time I changed my oil. It was a few weeks back. Just like the first time 6.1 quarts. Do the warmup to check and it's just at the bottom of the stick. I can't remember, but I think I added about 8 more oz's until it read full. Weather was hot outside. Checked the machine for several days and it read full. I'm not sure Honda didn't misprint this in the manual. My Ford 250 manual called for 15 qts of oil which was a misprint because 13qts is full.
