How did these cars get this stereotype of being so frail? This thread made me look back at my history from years ago and my C2 race car should be a ghost considering the sentiment around here. 8 years ago I see I had run 5 race weekends (sprint & enduro races, not DE) including street driving to/from the track for over 3,000 miles on the same fill of mobil1 0w-40 over the span of a year. And the same car/engine has continued to be raced since then...

That's awesome to hear. Wish there were more people like you sharing these stories instead of just the endless parade of doom and gloom!

DT40 should never be used on the track. It was not developed or proven for track use.

You need to run XP oils on track, and change to DT oils for the Street. It sucks to deal with, but we have proven over and over that this is a requirement. The roles could not be more different t between Street and track for these engines.

Well, since going through 100 liters of XP9 on our 7,000 mile round trip of the country and tracks was cost-prohibitive, we left the 996 at home and brought the E39 M5.

The M5 had a fresh clutch and ground control coilovers so it drove well and we didn't have any issues on the transits or on track. We ran the liqui moly 10w60 and burned about 4 liters over the 7,000 miles, which is pretty great all things considered.

Brakes were an issue. Even though each track session is just a recon lap followed by a standing launch and two hot laps, the M5 on the Michelin PS4s was making a ton of brake heat and the HT10s didn't last the week. We put in Porterfield R4-E pads and kept bleeding RBF660 through it and it was fine.

It's funny reading back on this my synopsis for choice #4 was *exactly* accurate. We added about a cup of oil a day. The best part was that I feel like we got half of an oil change in since we added so much fresh oil. We brought 15 liters with us with the intent to do a change halfway through but the schedule for OLOA is too daunting.

I HIGHLY recommend One Lap of America. If you're on the fence, JUST DO IT.

Yes the Motul and Millers Nano are good for street and track. Pricy but superb.
