The car has no clue what oil you put in it at all. It's based off miles and driving conditions if you were using the semi synthetic dealer oil. Unknowing what oil is in the car, I wouldn't go too far past 7000 on the synthetic. What year is your Cruze and has it had a ECU Recall done? That can change when the Oil Change message comes up.

As for Mobil 1, if you insist on that brand just use the original silver top and skip the extended protection. Still 7000-8000 recommendation for the silver top. Quite a few of us is using AMSOIL Signature Series and run it for 10,000-14,000 miles (after used oil analysis is taken). I had an oil change in January and have my next one scheduled middle of the month. If I kept using Mobil 1, I would have been 3 changes in by now.

It does not calculate based on the type of oil, but if it says "change oil soon" you're at least at 10,000 miles on that oil and definitely need it changed, synthetic or not the filter is going to be clogged completely soon and not properly doing it's job. These cars are very sensitive to the type of oil used (if it's the turbo model) and synthetic is better for it, so midas wasn't wrong, but it was definitely too expensive.

Mine comes on at 8000 for my driving habits. Been on for about 3 months now.

Mine must last an obscenely long time then, I drive the **** out of my car (always) and it takes forever for my percentage to go down lol

I have some idle time in there to account for it. 30 degrees and a 2 month old, I may leave the car running when I go grab the kids from their moms or daycare. 11-12 is different from the rest of us unless they had the ECU recall done on the auto equipt cars.

What Anthony was saying pretty much. Short trips and letting the car idle for 2 hours to warm up because it takes forever causes that oil life monitor to be short. My mom's 2016 Acadia barely made it 4000 miles before it was at 0% I believe my car was at about 8% when it started warning me to change it. That was about 9 months from the last change already. With Amsoil SS we usually swap filters out at 6k miles since it's up top and only requires a wrench. I can do it in about 6 mins not spilling it, I usually just break it loose and go look for blue shop towels and a flat head to remove the old o ring.
