My oil light came on last night this car has never had a problem and then im leaveing the firestation and the light is on so is the battry light. i checked the battry it seems fine just dont know what to do about the oil light.

If test light is a 12 volt light tester AND ILLUMINATES BRIGHT it shows that a component is actively trying to complete a circuit and yes drawing power causing a drain on your battery, now if test light illuminates low, possibility could just be ecm memory or antitheft system active . either way this test should only be done with a 12 volt test light as if you use a 5 volt (computer friendly) tester , false light will have you chasing a ghost. trust me. that trick helps by checking for parasitic draws a 12 volt tester does not illuminate when keep alive memory voltages are present . those voltages are not enough to drain over night. good luck

sounds like a head and or head gasket problem when u overheat u can damage warp head or blow head gasket look at oil if milky look possible getting/having antifreeze leak into oil or if white smoke coming from rear exhaust sign of antifreeze getting into cylinder

may need a heavier weight oil instead of 5/w30 try 10/w30/40 may need low end set up near 7/800-900..

No idea with my head under the bonnet ,could be anything from a loose oil filter to a oil cooler pipe so unless your local to alicante spain then ask a local mechanic to have a look for you

if it gets louder and faster as the engine speed increases then a piston is knocking...if it is just at idle like you said then it could be a bad oil pump if oil light is on at idle or it could be the connecting rod knocking on the crankshaft because it is loose.

I will have to disagree with this FORUM page you are talking about and cannot validate how an oil filter will cause a "film"

sounds more like oil pressure issues

to diagnose you MUST actually check oil pressure

Im not sure I am following you. When it gets dark enough the "daytime" running lights should go off and the headlights and tail lights should come on for night time driving. The head light switch must be set in the "auto" position.
Regards.

Did anyone leave any rags under the intake?
I had a client have this happen to him and it caused some real problems.Check the oil level to see that it's not low. If you have an oil pump problem, the light should have come on. Hope this helps a little.
