I must concur with the One-Eyed, One Horned, Chromed out Purple People Eater. Once I do an oil and filter change....I do NOT check my oil at any time during the next 5,000 miles, unless, as decribed by Mr., there is a puddle under the bike, which has never happened with any of my GL-1800 bikes. I do watch the oil pressure light on bike start-up, and that is it.
