How much sooner do you guys change your oil after spraying it at the track?

I changed my oil (Mobil 1 Synthetic 10W-30)
made 11 dyno pulls
150 miles of street driving
made 1 N/A 1/4mi. pass
2 NOS 1/4mi. passes

How soon should I change it again?



Thanks,
Jeff

 

With synthetics such as Mobil 1 ....you should be fine to 3000miles even if you spin it up to 6000rpm frequently. I prefer to run 15w50 though. Now if you were driving on dirt roads you may need to change the oil more often because the oil gets dirty quicker.
