There's always been two VW's in our driveway. Lately it has been a 2012 TDI Sportwagen (2.0) and a 2010 Golf (2.5) gas engine. I'm 300 miles over the 5,000 mile oil change on the 2010, which has 189k, and I'm scheduled for an oil change tomorrow. To tie me over, last week I put a quart of the liqui moly (4200)(5W-30) that I use for the TDI in the 2010 golf, without reminding myself that oil is different for both. The 2010 (which uses 5W-40) is running fine, but slightly rough at first start, which has happened on occasion when using the correct oil. But I now have a check engine light. I checked the oil and it showed a quart low and I added the correct Liqui Moly (blue label). Car sounds like it did when I first drove it off the lot 8 years ago, but Check Engine Light is still on. We've been religious about changing the oil and have never gone more than a few hundred miles over the next required oil change. The mechanic I use is fantastic and literally 200 yards from my house.
Questions:
1. Have I done permanent damage to the engine?
2. And can the check engine light be unrelated to the misapplication of oil?
