fishindevil Posted October 31, 2015 Report Share Posted October 31, 2015 A quick question for the car guys in the know a 2006 Chrysler Sebring 2.7 litre engine needed a litre of oil and it's 5w 20 and it was just above the add line poured in a litre of oil and almost immediately the engine light came on checked the oil again and it's showing just a little bit above the max line could that be enough to set the engine light on ?? It's maybe a 1/8 inch to a quarter inch over the line just wondering if that would cause any problems thanks Link to comment Share on other sites More sharing options...
Freshtrax Posted October 31, 2015 Report Share Posted October 31, 2015 I would hazard a guess that the excess oil may be sucking through the PCV and is messing up one of the emission sensors. Is oil pressure within spec? Why is is loosing a L of oil in between oil changes.? That's concerning. Link to comment Share on other sites More sharing options...
Old Man Posted October 31, 2015 Report Share Posted October 31, 2015 (edited) I suspect the oil level and engine light is just a coincidence. You have another issue, ie. malfunctioning O2 sensor, ignition issue etc. etc. Can be one of a 1000 parameters tracked by your cars power train control module. Only way to know for sure what it is, is to dump the codes. Either buy a OBDII code reader or take it in to get them read.

kickingfrog Posted October 31, 2015 Report Share Posted October 31, 2015 Any number of things. Tighten the gas cap Clean the threads on the gas cap Recent fill-up of not-so-good gas? Near empty gas tank with condensation in it due to cool/cold temps. etc, etc etc Link to comment Share on other sites More sharing options...

SBCregal Posted November 1, 2015 Report Share Posted November 1, 2015 you can pick up a bluetooth obdII adapter on amazon for about 20 bucks shipped. if you have a smartphone you can download a free app to read the codes. you can pull most codes with that combination, as well as a few other neat features. the code number and google will get you a whole bunch of info and tips.

fishindevil Posted November 1, 2015 Author Report Share Posted November 1, 2015 Seems it could be upstream o2 sensor or downstream o2 sensor or inefficient CAT Link to comment Share on other sites More sharing options...

bigbuck Posted November 1, 2015 Report Share Posted November 1, 2015 That usually means the catalytic convertor is toast. You are burning oil and that is murder on the cat. Mechanics have a saying...'catalytics dont die, they get murdered'. Something caused it to die, you need to figure it out before replacing it.

fishindevil Posted November 1, 2015 Author Report Share Posted November 1, 2015 They also added some fuel injection cleaner and said it could have even been some bad gas !!!! Hmmmm that one code can mean a lot of things as well at least it wasn't a bad cat as that would have been $$$$$$$$ Link to comment Share on other sites More sharing options...
Freshtrax Posted November 2, 2015 Report Share Posted November 2, 2015 Fairly confident oil was being sucked through the PCV and messing up the readings. . Glad it all worked out. You still need to figure out why there was a litre of oil missing in the first place. Link to comment Share on other sites More sharing options...
AKRISONER Posted November 2, 2015 Report Share Posted November 2, 2015 (edited) guys, dont overfill your oil, it puts a pile of pressure on your seals...you are better off running a little below the max line than over. When you overfill your oil, you get oil blowing through the seals and into combustion...which is not good on all accounts. You can actually severely damage your car doing this.
