Started my 360 up today. oil pressure gauge immediatly shot up to 70. went for a run and pressure rose to the 140 mark at just a reasonable speed. If I put my foot down the needle went up to its maximum. should I be worried or will it be something simple.
I would add that when stationary with the engine switched off the needle registers about a quarter of the way to the 70 mark so it might be the gauge?
