I have had my ECO 6M since July 2011. Changed my oil myself 3 times so far Mobil one twice and now on Royal Purple. I am at 20,800 miles now. Never have had an issue with the check engine light after an oil change. I have seen the check engine light only twice - both for Lean Bank 1 code. Light came on after a long highway trip each time the morning after the drive. I cleared the code and has not come back.

 

I remember reading something on the GM Techlink website about the oil fill cap. They had a picture of one that wasn't on straight and it wouldn't seal. I think there is an O-ring on the cap you could probably match up at a hardware store but a dealer might warranty a replacement cap. You might have a problem with the PCV system and the fix is a replacement cam cover. My first choice would be a new fill cap because that is the cheapest and most logical part.

 

What code are you getting? Loose cap where? Not the filter cap pouring oil all over the place!

 

What code are you getting?

This. Without knowing what code it is you have no idea whether it is or isn't related to something affected by an oil change.

BTW, if your car is under warranty why did they charge you to fix the cap and what exactly did they do?

My Canadian Eco has only ever had one SES light and that was during a ridiculously heavy wet snowfall where the lower grille shutters got packed with snow while driving and wouldn't function properly. A night in an underground garage melted all the snow and all was good the next day. I also had the upper grille blocked so all cooling airflow was coming in from the lower grille which is not how the car is designed to work so I write that "issue" off as operator error.
