If you hear clacking noises while idling then the pump may be bad but put a manual gauge on it to see what the pressure actually is. Use 10w30 oil.

Don't thicken the oil as it willclog the rings then you'll have old smoky it only takes 4 psi to turn the light on so as long as youhave pressure don't worry about it. Also a lot of oil filters can cause this. I only use and recommend napa, Purolator, wix, bosch and ac.
