Please forgive me if I have posted my question in the wrong forum. I have a Miller Bobcat 225 welder/generator that I bought strictly for standby power purposes. It has a 2 cylinder, 23 HP Kohler engine in it. I bought it new about 6 or 7 yrs ago and it has about 40 hrs. run time on it. Even though it has low hours on it, I decided to change the oil and filter. The Kohler manual that came with the engine says it holds 2 qts. of oil including the filter. The manual also tells you to fill the filter with oil before you install it on the engine. I filled the filter per the instructions and it took a few tries because the filter fabric kept sucking up the oil. When I was finally satisfied that the filter was full, I installed it and tightened it up. I then took the remainder of that quart of oil and dumped it into the engine. I added the second quart after that. When I was finished topping off the oil, I checked the level with the dipstick. It was reading a little on the low side, but I felt that there was plenty of oil in it and it did not concern me. I ran the unit for about 1/2 hr. with a load on it, and then shut it down. I waited for the oil to settle in the crankcase and when I checked it with the dipstick again, it read in the same place, or, a little bit low. I picked up a third quart of oil today to top it off a little bit to bring the oil level on the dipstick where it is supposed to be. But before I added oil, I checked it and now for some reason it is reading high on the stick. There is a shaded area indicating FULL and what I assume to be LOW or ADD. Right now it is about 1/4 inch above the full mark. What gives? The manual says it holds 2 qts. and that's all I put in it. Will running it with the oil level a tad high harm anything? Or should I drain some out until the stick reads correctly. I just don't want to screw anything up if it is overfull. I really like this unit and don't want to mess it up by doing something stupid with oil capacity.
