Engine light on! 2012 Sonic Turbo 1.4L

[Sonic79]

Modified stock air box, and no rear cat or muffler on exhaust!

Never had a problem until today the engine light came on, car runs fine no problems at all ?

Did my first oil change last week after 9k miles about 10% left on the oil life from onstar emails. I used 5-20 semi synthetic oil...

I called onstar and they did a test, they said take it in with in 7 days! Something with emissions...

Any Help
Thanks
Brian

Do you have an OBD2 scanner? There are quite a few emissions related components on the car. It could be any number of systems that has a failure. The rear catalyst isn't monitored by an O2, so it's not that.

Ultra gauge will give you the code to see what it could be.

you can delete the rear cat without causing a CEL?

1) 5-20 is the wrong oil
2) 9 k on the first change is way to long

Went by the oil gauge from the factory! I dont think 5-20 oil is the issue!!!

Yes, the first cat (catted down pipe off of turbo) is the only one that is monitored by the ECM. A test pipe is a cheap easy way to open up the exhaust without doing anything else.

Thanks for your input guys! Keep it coming...

The first oil change has metal chavings it that have been in there for 9k miles. Not healthy. And modern motors are designed to run on a specific weight of oil

What are metal chavings?!

 

[$ub$onic]

Shaving.... sorry

 

[rdss]

Shaving.... sorry

Don't apologize to me, you should apologize to your elementary teachers....

It amazes me that someone would spend good money on a new car and then go 9000 miles on the first oil change! Sheeesh.

 

[rdss]

The dealerships swear by the OLM.... When you preach it to the consumer the majority will follow. I will push Mobile 1 to 5,000 but that's as far as I will go.

You and I both! Some will say we are wasting our money but I'll gladly "waste" $35 for Mobil 1 EP and an OEM filter every 5k!

 

[rdss]

We could probably get away with 8k and just swap the filter and top off. But like you said, you can buy piece of mind in this situation.

Some people just dont know. I know what Chevrolet intervals say and the oil % in the dash may claim but we cant go by that. Some of us know alot about turbos and some dont know how to change oil. I look at this forum as a family. Sometimes we got to teach our brothers and sisters a how to. You know?

 

[pwntbywombat]

Even on a fully synthetic oil, which the 1.4 didnt come with from the factory, i wouldn't go more than 5000 miles on a turbocharged engine.
