Engine Oil for DD/Track

[AZP Installs]

We tracked on the Motul 8100 5w30 X-cess last season in hot/humid NE Summers without the oil cooler and had no issues daily/track use over the course of 4-5K interval changes. We moved up to the 300v 5w30 and the test have come back essentially the same as the 8100. Then we moved up to the oil cooler (Perrin) and results from Blackstone are great. We generally will alternate between the 8100 and the 300v just to keep the detergents in there.

Have fun with this one:

Tests dynamic wear load protection, flash points, breakdown temps etc.

Just points of reference:

The miller nano drive (0w30) rates at 105k psi (Excellent), but the Amsoil 0w30 is also at 105k psi and it's readily available and less money.

Even the Pennzoil High Mileage 5w-30 Conventional scores a 102k psi.


The Motul 300V 5w30 Racing oil scores 112k psi... BUT it's a racing oil so you're forgoing your additives and detergents that are important for a street driven engine.

For reference I run Amsoil 0w30 all year long in my FRS.

Surely there is something in between that fits my intended use. I plan on sticking with 0w20, is there any reason why I should go with a 0w30 or 5w30 instead?

A 0w30/5w30 or even a 0w40/5w-40 (summer only) would be advisable considering how little oil pressure these engines make under track conditions.

In that link I posted above, the 300V (racing only) scored very well (112k psi) but it's street counterpart the 8100 only scores 76k psi and the 8100 ECO oil does even worse and many conventional oils out both 8100 options.

In your position, looking for an oil that's up to the task for DD/Track (additive package and high shear and temp stable) it appears there's better options than Motul for your application and cheaper options as well.

I had fun with it. It's meaningless. He should conduct these "tests" based on the ASTM tests used by the oil industry, but he can't afford it.

Some good comments here:

As per the other times that this has been posted (this week even), he's using one parameter that if you reach it you have already failed in lubricating your engine to state that any given oil is better than any other.

His testing method is not representative of any place in any engine that you or I are ever going to see.

And his conclusions have absolutely nothing to do with the parameter of choice by which he ranks them.

And for the record, Motul 300V does have enough detergents to handle a ~6k mile OCI with no problem. There are several uoa's in the long uoa thread.

I agree with this and your observation about the oil blog but that's why I said, "have fun with this."

That 540Rat test is fun though, it's not necessarily indicative of what's inside our engine but it is a test of one parameter and while that parameter doesn't mean much to our engines, it still fun data to compare.

What I did find was applicable to our uses is the breakdown and flashpoint temps. Find yourself running 280F oil temps and it may be something to consider.

It's dyno proven to add 6wp and 3wtq to a stock 86 and myself and others have UOAs showing clean bills of health after 3k miles of E85 fueled track abuse and 7k miles of spirited street driving.

Out of curiosity do you have a psi gauge? Just curious if you've logged the 0w-30 while on track for temp and psi.

No

Decided to go with Motul 8100 Eco-Lite 0w20 since I DD quite a bit, ran at Streets of Willow last weekend and saw max oil temps of 240F in 90F ambient after 8 hot laps with a JR oil cooler. I will be doing a UOA once I change the oil as well. Looking to keep temps around 220-230F to maintain safe oil pressures, any recommendations on the next cooling mod after an oil cooler?

For the track, I'd rather run Motul Eco-nergy 5W30. It has a higher HTHS which will keep your bearings happier during track time.

There is some track oil pressure data in this thread, although keep in mind that the higher HTHS oils 300V are being compared. The 8100 series 0W20 and 5W30 would probably show lower oil pressure (especially after some time on the oil) due to their lower HTHS.

Rotella t6 $22/5qts is plenty good for track and daily driving. Its prob the most popular oil for people who track their cars. Really don't need to shell out a lot of money for bandwagon type brands. If you want to get a little fancier, brad penn $6/qt oil is also great, but much harder to find readily. Valvoline vr-1 $9/qt racing is also great too and is available at autozone and such but not really needed unless you run e85.


I don't know how well our cars wear but 3 track days on a single change might be too much. Only way to tell is universal oil analysis.

I was just doing some reading on the endless oil threads, and it seems like the general consensus is that xxW-40 is too high of weight.

After much contemplation, I went with the Eneos 0W-20. I average around 2-3 autox events/month and some street miles on my basically stock FRS. We'll see how the oil performs, but based on others' results, I should be in good shape.

Is eneos 0w50 to thick for track? I was told it was ok for our cars.

They are wrong.
