I just had no problem running an unserviced car in tier 12. I did the Hunter race at Suzuki, followed by 8 laps at Indy and the car was shot. I went ahead and still ran 15 laps at Richmond completely unserviced and still had a lead of over 1,000 yards on the final lap. You can do one tier at a time or more between servicing as long as you do bot management, so you should easily be able to knock out 5 tiers per day if you have time to race for 15 to 20 minutes every 3 hours.
