Manual says to fill with 4.25 quarts. However after draining the oil, changing the filter and putting in exactly 4.25 quarts, I'm slightly under-filled. So I added a little more and I'm better but still a bit under the max hashmarked area on the dipstick. I've read other threads regarding this and it seems that some people's manuals say to fill with 4.75 quarts and others say 4.25 like mine does. Not sure why the dipstick has to be so hard to read also. Do they really need that curve in it which skews the results? Anyway I digress. I just wonder if anyone else has a similar issue. To me, this should not be rocket science and just work. Thanks
