I'm planning to use Redline 10W30 in my Integra GS-R for my next oil change. The problem is, I'm at a complete loss for drain intervals. I do like to run to redline, especially when I'm at college where my car is as much a tool for blowing off steam as it is a mode of transportation. I also autocross on occasion. Given those conditions, I am thinking 6-7K but I really have no baseline for comparison. I haven't turned up anything in forum search either. Your advise is much appreciated!
