So my oil warning light comes on once in a GREAT while. Usually when the RPMs dip down a bit while the car is idling. As soon as I press down the throttle is goes away. Is this some what normal? I checked the oil and its not low.

 

On hot days and after a warm drive my IX would start to flicker the oil light at every stop light. This happened when the car was brand new. 48k miles later at 30psi and solid 11s at 118mph shes still running good.

I noticed when I made the switch to E85 the oil temps went down a bit and now my light hardly ever flickers unless the car stumbles real bad at idle.

 

if you dont have any od noises, i would just swap out the oil pressure sender. its prolly going bad and just making the like some on.

 

this has been beaten to death...its the oil pressure sending unit thats going bad...replace the sensor and it will go away
