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 that spec sheet.......

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

You should use Eneos. It's is better because its hard to find and they have awesome marketing. You should also consider the opinion of someone with a heinuous props ranking who doesn't even have a turbo Miata

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.

Let run the mystery oil......the one made by one of the most wealthy companys in the world that cant afford a spec sheet.

lolz.. Yea because no one runs T6 on the track... You obviously get out to the race track very often

Yes, Eneos is clearly the superior oil due to the availability of its "spec sheet" on a google search.

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.

Thank you for conceding defeat, now profess you immortal love for my masculinity and benevolence and you will be forgiven.

"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.

lol @ 40hp to pump that oil.

Also, who gives a ---- about VI? I care about the CST score at 100*c second only to zinc and moly, and fuel shear, and price, and virility.

So you show us your oil analysis, I'll show you mine?

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?

Wow....you're an idiot. Viscocity index is a measurement of the consistency of the fluid over a temperature range. The higher the number the more consistent the viscosity, not more viscous.....

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.

Call me an idiot all you want, you've never contributed a god damned thing to this forum other than being an annoying pest.

This is clearly an inferior oil to the MotoGP oil I can buy for my shitbox Miata.
