2005 Saturn Ion Q&A
2005 Saturn Ion Question: My car is using oil and the garage cannot find the reason.
This all started when my check engine light came on. The oil was down by a quart. Since it was time for an oil change, that was done. Now it has only been 200 miles since that, and the check engine light came on again and it is down a 1/2 quart. I also have had the knock sensor replaced twice. That is also still showing a problem. My fuel gauge is also showing some problems. I was advised to take it to the dealer to see what they can find. My car has now 102,000 miles on it. - Saturn Lover
The oil level is NOT the reason the yellow check engine light is on! You have two seperate problems. Mechanic needed, to find oil leak or consumption problem. Then the mechanic can scan the computer to find out why the check engine light is on! (or vice versa) - pushrod
PUSHROD IS CORRECT; A LOW OIL LEVEL WILL NOT CAUSE YOUR CHECK ENGINE LAMP TO ILLUMINATE. THE KNOCK SENSOR AND FUEL LEVEL SENSOR WILL ILLUMINATE THE LAMP DEPENDING ON THE NATURE OF THE MALFUNCTION. HOWEVER, NEITHER OF THOSE ITEMS WILL CAUSE NOR WILL THEY BE AFFECTED BY A LOW ENGINE OIL LEVEL. SO YOU ACTUALLY HAVE THREE SEPARATE PROBLEMS BUT SINCE YOU ARE CONCERNED MOST WITH THE OIL LEVEL, LET'S TALK ABOUT THAT. HAVE YOU NOTICED ANY OIL ON THE GROUND WHERE YOU NORMALLY PARK? DO YOU SMELL ANYTHING OR SEE ANY SMOKE AROUND THE VEHICLE WHEN THE ENGINE IS WARMED UP AND RUNNING? (THIS WOULD BE EASIER TO NOTICE IF YOU DRIVE THE VEHICLE 10 OR 15 MILES, THEN PARK SOMEPLACE OUT OF THE WIND. SMOKE WOULD TEND TO BE VISIBLE UNDER THE HOOD OR ANYPLACE ALONG THE EXHAUST SYSTEM UNDER THE CAR. ANOTHER QUESTION I WOULD LIKE TO ASK YOU IS IF THE VEHICLE HAS BEEN IDLING ROUGH OR POSSIBLY HIGHER THAT NORMAL. IF THIS IS THE CASE, YOU MAY BE ABLE TO FIX IT YOURSELF FOR NOT A LOT OF MONEY. - Rojo1
