Hopefully you will be fine. Meny moons ago I had an old bike which had a bit of a valve issue and used a little oil. One day I was out on a run and not until I went up a steep hill did the light come on. I stopped immediately, turned around and coasted back down to the flat where I checked the oil. I couldn't even see it!I added 3/4 quart to get it back up to the top fill line. I think that high fill to low fill line is like 1/2 quart so I was a little under the low line. Red light and little oil can never came on. I just babied it home and then topped it off once it cooled off. Cleaned up the mess this morning with dish soap.
