Can a thicker 40 weight oil fix low oil pressure?
But thicker 40-weight, by its very nature, has more internal friction, so it won’t flow quickly enough to fill the spaces between bearings (bearing clearances. In other words, thicker 40-weight oil can’t create a consistent lubricating film in an engine deisgned for 30-weight oil.
What happens if your oil pressure is low after an oil change?
If this happens, it’s bad for several reasons. Low pressure means the critical joints and friction surfaces of the engine are not enough lubricated, which will lead to serious damage. There could still be low oil pressure after oil change. If this happens, you should pull the car off and turn off the engine as quickly as possible.
What kind of oil to use for low oil pressure?
Let’s say your engine requires 5W-30 and you want to substitute 10W-40 oil to fix low oil pressure issues. First, the 10W-40 will affect cranking and oil pumping at cold startup. So the engine will be more difficult to start and it will take longer to build pressure.
Is it normal to have zero oil pressure?
No abnormal noise and temps normal. No low pressure warning light. I have zero oil pressure on gage. No leaks and has plenty of oil. Temps normal. No abnormal noise and no warning light for low oil pressure. My car has an automatic transmission.
What happens if I put 20-50w oil in an engine that needs 5?
A 20W/50 oil is much thinner at high temperature than a 5W/30 at a low temperature, so the viscosity will not hurt your engine. BUT and it is a big but! Most 20W/50 oils do not meet the anti wear requirements of modern engines! You must look at the API logo and confirm that the oil meets the minimum specified by the manufacturer.

When does the low oil pressure warning light come on?
My Low Oil Pressure Warning Light Comes On and Off Most modern vehicle models come with an oil pressure switch that activates a warning light on the dashboard when dangerously low oil pressure is detected. For the light to come on, oil pressure has to drop below 5 or 10 psi at idle, depending on vehicle model.
