Paul: I have had the same situation with my oil pressure gauge and engine heat gauge for years. Whenever I used my radio, dash air, windshield wipers, headlights, etc,etc, my oil pressure would go down and the engine temp would go up. It is probably a ground problem. Newell sometimes puts too many systems on the same ground. We've never really been able to completely cure the problem but are aware of what causes it.
