Dieseladdict,

You are completely wasting that quart of oil you "flush" with. With all of the places the old oil is trapped in the engine, you are fooling yourself if you believe that is a worthwhile procedure.

Larry,

You're the person that seems to be into witchcraft. This mantra of changing your oil every 3kmiles is rediculous. You should know better but you refuse to look at it with a clear mind.

Joe
Don't change it often, you're wasting your time and money!
