There are no misfires or codes. Is there a program or app that I could check for any live misfires on this car? More familiar with the fords where I use forscan to see, also have torque pro app but it wasnt working last I checked.
Doing a mobil 1 change also, this motor eats oil like crazy.. without any visible leaks or burn off. Talking a good 2 quarts every 5k miles.

I substitute 1 qt of 10w 30 at oil changes and my LLT burns next to nothing. Used to use 1/4 qt between changes.
Next time its down on oil try a bottle of 10w 30 Dexos.
