what weight oil do you guys run on the track?

We have been using 15W-40 in the lemons cars and have noticed less consumption and less lifter tick. Supposedly the additives in it are good for a gas track car without a cat. It is changed after every race and comes out still looking pretty good. We will be doing an oil change here in a couple weeks and sending it off to blackstone to have them take a look at it.
We have been bouncing around the Idea of going over to a synthetic 5W-40 for the 24 hour race, but this stuff always looks great after 14 hours of racing.

Lets see, Rotella provided more zinc, phos, magnesium, significantly more moly, it absorbed more fuel and sheared less for a higher end viscosity, making it a better oil in just about every way. The only confounding variable is break-in because the first two Rotella UOAs had higher wear metals (still tiny numbers) and I suspect that is from break-in. I will do another analysis this summer or later this year since I have a new head in the car and I don't want to skew the UOA data again.
Where did the AMSoil do better again?

Yes, lets compare marketing packages rather than real, turbo Miata related data.

You're also recommending an oil with a CST score of 18 at 100*c for our engines with relatively light tolerances that typically operate under 250*f oil temps. This oil might work in something like a Vette that is built super loose on the big-ends of the rods since they run incredibly hot, but even then the oil is too thick. The Rotella T6 is a little low at 15 CST at 100*f and that's a good thing considering that we're not pouring that oil in a tractor.

Ok, it's obvious Rotella is a great oil. I do find it strange that they do not make a spec sheet though. I can't honesly argue that the Eneos oil is better or worse than the Rotella and neither can you guys because there is no spec sheet or direct oil analysis comparison. They are both great oils so lets just agree to disagree until there is some hard proof and stop the thread jacking. ![Thefinger](https://www.miataturbo.net/images/smilies/thefinger.gif)

"Great oils" if you want something extremely thick and no UOA available. A spec sheet doesn't make an oil great, one that survives a few hours in a super-fat track car does backed-up by data does.

EDIT: Also your tracking your car right? And its turbocharged making over 250whp? Or are you just giving advice based on what the oil company is telling you?

Thank you for being the man here, now let me take some notes on how to be an adult instead of an e-thug and maybe one day I will mature.
"Great oils" if you want something with a supreme viscocity index and not by diesel rigs. A spec sheet doesn't make an oil great, one that is used in Moto GP super bikes, Formula 1 cars, and produced by the largest most technologically advanced oil producer in asia and arguabily the world.

I like how you think Redbull F1 are using off the shelf eneos 0w50. Diesel oil makes sense when you consider the AFRs we run and the resistance to fuel shear.
I'm aware, and although it's great to have a high VI, it's still too thick at 18CST at 100*c. As I understand it, something between 11-14 is a better number for a racecar or track car. ~10cst for a street car at 100*c.
