Hello Everyone. A year ago, I decided that I needed a Honda lawnmower to help me bag cut my lawn and at the same time bag my leaves. (I had gotten tired of raking leaves). I bought a Honda HRX217VYA and I have been very pleased with it. It came with a 12 oz bottle of Honda 10w-30w motor oil with instructions to pour all the oil into the engine. Now it is time to change the oil, the instructions say that it will take 12 to 13.5 ozs of oil but not to overfill it. I did not read the instructions that say to change the oil while the engine oil is warm because then the oil drains quickly and completely so When I poured it out, I only got about 8 ounces of oil. I poured it in slowly, checking the level to be careful not to overfill it and now it is full of oil but again it only took 8 ozs. Is it ok to run my lawnmower the way it is as long as I did not overfill it with oil? Thank you for your help in this matter.
