Why is my oil light on after oil change?
The light could be on after an oil change because of an issue with the oil pump. If this is the cause, there could be not enough oil circulating through to the various parts. Performing regular oil changes should help prevent this from happening, but parts do wear out.
What would cause the oil pressure warning light to come on?
When the oil light on your dashboard comes on, it might mean your vehicle has low oil pressure. This drop in oil pressure could be a sign of a few things: you are low on oil, your oil is dirty, or you have an oil leak.
Can an oil change improve oil pressure?
This slight change in oil viscosity can make up for the increased bearing clearance, increasing oil pressure back to normal. The best way to fix this kind of oil pressure problem, though, is to repair the bearings. A higher-viscosity oil may resolve this problem, but a new oil pump is a better solution.
Why does the oil pressure light come on after an oil change?
Low pressure means the critical joints and friction surfaces of the engine are not enough lubricated, which will lead to serious damage. The Reasons for Oil Pressure Light On After Oil Change 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.
Can a PF2 oil filter cause change in oil pressure?
The presence of the valve does restrict a little flow by design, but not having one on cars that require them would do more harm than good. For the record, the PF2 AC Delco filter I used on my truck did have the anti-drainback valve…it just sucked at supplying oil to the engine. – Jus – Rebuilding your journal bearing turbochargers since 2004.
What happens when you change your oil filter?
A swift drop in the oil pressure is a cause for concern. A pressure change can cause serious problems within the vehicle. If the oil filter is clogged, the exhaust coming out of your car can be black or dirty.
Why is my oil pressure sensor not working?
For the sensor to function, it needs one or two wires going between the instrument cluster and the oil pressure sensor. The engine compartment becomes hot while you are driving, and there are constant vibrations. This can cause wirings to get a bad connection or actually fail and break off completely.

What to do when your oil light does not come back on?
If the old oil filter would not permit oil flow, the light will turn off when you start the engine with a new filter and oil pressure should return to normal. If the oil light does not come back on and the oil pressure gauge reads properly then the issue is resolved. If the light comes back on, turn the engine off immediately.
