I'll definitely provide updates. I occasionally autocross my car and I can hit >230F after only a few runs. I will be autocrossing again this weekend. I'll post again after that.

This past month I've been limited on time in preparing my car for autocross (work, graduation, holidays, etc.) so I had to quickly change my oil as soon as I drove into my garage. This is when I noticed how thin the oil ran. (I normally have the engine cool when I do an oil change and the oil never seemed that thin. I have the car on jack stands, rotate the tires, set pressure, etc. and drain the oil overnight.) I also have a Lubricheck (http://www.lubricheck.com/) to see how good the oil is and never noticed anything out of the ordinary.

 

Also for those of us who dont want to change our oil because we "believe" its right, there is science to back up the extended changes.

I use royal purple and did 5000 mile changes and sent it to blackstone labs who said there was no to little wear and to go longer intervals. i was up to 13000 and they said that (in my opinion with the metals, and other data that that was the limit i was comfortable with.

I backed off to 10,000 miles just because it is easy to remember.

Again, stop believing and "its what I have always done" and do the research, it will save you time and money. Don't forget, in the early days 1000 mile oil changes were the norm, then people had the same issues when 3000 mile changes came around. We know it works because of the testing and science behind it.

Early oil changes hold as much strength in discussions for me as "there is no replacement for displacement"

 

Yes, you may extend your oil changes to 10,000 miles. It's totally dependent on your driving style and conditions, though. For my car, it's about 8,000 miles. In an autocross season, it's like 5,000. Also, check your dipstick every time you fill up gas. I usually have to put in a quart every month (be sure to analyze the oil before you put in the new quart of oil).

 

Temperature after a couple of runs and idling for some time in the grid. It hit 234F at one point. Definitely should've shut the engine off or applied some throttle to get the water flowing more.




This is the temperature immediately after a run. It's definitely an improvement over previous autocross sessions but it's important to know that the ambient temperature is much lower than normal. It's definitely not the coldest it's ever been (last month it was ~70F, this month it was 80F, usually it's 90-100F). I've been autocrossing for a while now and I'm certain there's been an improvement from just changing to the Rotella T6.

 

That is impressive. I was talking to a few Ferrari guys and geeking out on how they choose their oil brands and weights for track days. Same deal, what the temp out, whats the goal... up and down on thickness...
