My Oil light comes on and buzzes sometimes when I decelerate and brake. This
happens after the engine is warm and I've been driving a few minutes at
sustained high speed (3800 - 4000 rpm).

It quickly goes out and doesn't come on again until I decelerate and almost
stop. This happened a year ago on a long trip and caused me some concern,
but hasn't happened since. Is this anything to worry about?

The oil seems a little over the max level. Could this be the cause?

Thanks,

PAUL
