Redline's high phosphorus shouldn't foul the catalysts if you're truly not using oil. Seeing zero makeup oil, hope thats right.
In the past there was 3/4 quart added over 6,900 miles, which is still good.
At 52k and 55k km I was using Total Quartz Ineo MC3 5W30. I switched to Redline for the track primarily and decided to use it year round not to keep switching oil chemistries around.
The only oil usage was due to heavy track use. This summer for the track I switched to Redline 15W50 and I'll go back to 5W30 once the track is done for the year. The next UOA will show me how the 15W50 did. My data logging shows on the track the engine oil peaked at 266F. The coolant stayed at its normal value.
