And let me also clarify. I have seen cars, and there are posts here about being on the top of the fill level that smoke profusely during DE's. I am not suggesting to underfill. I am saying that there is a low fill level and a top fill level. Just stay below the top fill level. If this is his first DE I cannot imagine he will be running so hard as to cause oil starvation from these levels. For many oil change places a normal oil fill to them means putting it at the top of the stick, not knowing that with Porsche it is acceptable to be between the marks. Most shops would look at being between the marks as being low. I would hate to see a fun day of DE being ruined by being black flagged for smoking (not to mention the embarrasement).

And anyone that get's embarrassed from being black flagged (or meatball flagged) needs to understand that those flags can save you tons of money. Anything loose anything can fall off, a strange noise can be serious, and dropping fluids can ruin a car (not to mention screw up the track surface).

Dell - It's kind of funny to read the smoke screen comment above and look over to your avatar and see the cloud behind your GT3 ![Stick Out Tongue](https://rennlist.com/forums/images/smilies/tongue.gif)
(For those who don't know, it's the oil-absorbing "kitty litter" that's kicking up behind Dell in the photo - "kitty litter" is the technical term. Right?)

I agree with the recommendation to fill the oil to the top mark on the dipstick. Be sure to keep an eye on your oil level throughout the weekend. In fact, it's not a bad idea to check after every session. You'll probably get through the weekend without having to add any oil, but checking the level is cheap insurance.
In the 1,000 + 996 track days I've witnessed, (my track time + the other 996's at the events I've attended), I'vee seen 996's smoke, but not because the oil was properly topped-off. The smoke was attribitued to 1 of 3 reasons:
1) Gross overfill. If you overfill the oil by say 1/2 quart or more OVER the top dipstick mark, there's a good chance you'll see smoke. Whether you track your car or not, drive a 996 or any other car, it's obviously a bad idea to overfill. I don't recommend it.
2) Improper Cool-Down. If you run hot laps (not likely to happen during your first DE weekend) and don't allow the engine to cool down before you shut it off, you're likely to see smoke the next time you start the engine. The smoke will eventually clear up, but it will freak you out the first time it happens to you. To avoid this situtation, ALWAYS make sure to do a cool down lap (driven at public road speeds) before shutting the engine down. If the session is cut short for some reason and you don't get a chance to run a proper cool down lap on the track, find somewhere to drive the car at 30-50 mph for about 5 minutes or so before shutting off the engine and you won't have this problem.
3) The unspeakable. I only know of 2 and neither were caused by hi or low oil levels. Both involved older, high milage cars with questionable maintenance histories.

For safety reasons, you're better off removing the visor from the helmet altogether if you're not going to use it. Besides, the lighter weight will give you a performance advantage.

Just came back from Millersport today. My tech inspection and brake bleed are complete and my form for the DE is filled out.
Chuck Miller in Hillborough, NC is a cool guy - I think I have met my preferred tech.

Bob, you are almost there, just another two weeks and on the track. Hey, enjoy Rockingham this Sunday, should be fun. See you guys next week, off to the OBX to build track day points with the wife. Sorry I will miss the tech session tomorrow and some good stories from Dell. Way to go Dell! Great videos.

Thanks, Rich. An oil change tomorrow, Rockingham tomorrow, and DE next weekend - pretty close to perfection. I stopped by Leith tonight and heard that there's a possibility that I'll be riding in a Cayenne at 130 mph as it moves through the banked curves of Rockingham. Soooo, I'm planning to buy some adult diapers before going.

Another DE Question - I have front tires that are 7 years old. Just found out at Millersport. They're also a little cupped. Tread is OK, but wearing a little thin on the inside - still some life on the outside. So, the advice I rec'd from one experienced Porsche guy (with lots of track time) is keep the tires through my first DE. Wear them out a little more. Then, go buy a nice set of front tires.
Is it a good idea to keep them until after the DE? Or should I get rid of them and run new tires? The DE is about 1.5 weeks away now.

If anything you might have a bit more understeer but then again this is your FIRST trip to the rodeo so you won't be able to compare it to anything else ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Your tires will be fine and from what I remember when we had your car over at my place on the lift, the tires looked more than fine for a DE. Think of this DE as like our Saturday fun runs but with no police!!!

Thanks for the advice, Dell. I'll stick with the tires I have - you reminded me of what they looked like on the lift.
I considered making the change b/c the old tires were a little loud/tiresome on the way back from Rockingham. Probably can fix the issue by checking tire pressure and making sure it's right (I'll bet it's a little low in the right front tire).

I'm back, and I'm hooked. Here's a video from Helmut - a friend of ours in his Cayman S. What a fantastic way to get to really know my car! Great friends, great accommodations at the track, great instructor (Jeff Hare), great track, and no rain!
I also had rides with Jeff H. (track-prepped '99 996 like mine) and Dell (964 RSA race-prepped) for several laps. Incredible - no better way to describe it. Those guys can really drive.
