Don't use organic "Racing" oil unless you're going to be changing your
oil like you're racing, meaning every weekend. Someone else can probably
comment on the chemical reasons, but racing oil is not meant to be stable
over a long period of time after it gets contaminated (which happens as
soon as it's in a running engine). Either use regular high-quality
organics, or go to synthetics and extend your oil change interval.
