If your only running 4 days or less a year total I would stay with a yearly oil change. Although If you run 2 events back to back, you might consider changing it sooner. I also error on the side of changing the oil more frequently if I am pushing the car to the limits.
I would be happy to provide a used oil analysis breakdown for you. If you can post it here for everyone to see, I'm sure some other people will learn from the feedback.
Also, thanks for the endorsements everyone. If we can be of help, post questions within the technical forums mentioning Motul or anywhere else that is appropriate and we'll be happy to answer some questions. - Nick

Hi Nick, posting a question here directly so others can benefit. I have used 8100 X-cess in the past on my 06 3.8 m97 engine. No issues reported by BS labs. Are there advantages to 300V for a mostly track driven car running higher temps?

Reality is most these cars don't get used very much. I'll echo what others have said, with only a handful of track days a year, just change it annually and you're more than fine.
However, changing it more often doesn't hurt anything but your wallet.

The 300V is our flagship engine oil product and is a dedicated motorsport product. While the 8100 X-cess 5W40 is a Porsche A40 approved lubricant that will be formulated for a different purpose but still very much a high performing lubricant in a racing application. You are just limited in what you can do with the formulation to meet certain standards by the OEM’s. So there are definitely some advantages moving to 300V vs 8100 in a motorsport application and will also help with the symptoms you’re experiencing.
The major differences with 300V is that it is a full blown group 5 Ester based synthetic lubricant using our 100% synthetic Ester Core technology- esters have higher temp tolerances, a virtually unbreakble oil film (an oils ability to resist shearing), a lower traction coefficient (an oil’s slippery-ness= more power) and have a higher amount of lubricity vs traditional synthetics. Not to mention esters have a lot more polarity vs crude based synthetics (group 3 and 4). Considering these proven facts, the 300V should have an impact on your car’s performance.
In addition to that, 300V is also heavily friction modified to help the engine produce more power more reliably. We conducted a controlled engine bench test on a Porsche 3.6L Cup engine and we were able to extract 7 more HP and 1.2% more torque over the leaders in the synthetic market.
These are the main features and benefits. Hope that helps.-Nick

According to posts elsewhere from Nick at Motul, the Sport Ester 5w-50 is a appropriate lubricant for track only 2nd to their 300V. Search his other posts as he has some detailed info on it here. I have two jugs of the Sport waiting to go in to my car

Thanks for the reference BFT! Yes, I have provided some answers already. The Sport product will be positioned between 8100 and 300V. It is an API licensed product and is Ester based so it’s a great balance of a street oil as well as a track dedicated product. - Nick

If I have the car on the lift already, it's not a big deal to change the oil. That expense is almost in the noise compared with everything else. Until someone makes a darn good argument that oil needs a break-in period and doesn't get good until it has 1,000 miles on it, then I will continue to feel good about putting fresh oil in the engine at a higher frequency than called for! I also let the car "rest" after track days, so take it for what it's worth.

aryork, there are studies that show that the higher wear occurs in initial period following an oil change...it is documented...Oil additives take time to plate and "cure" inside and engine and new, high detergent level oil can remove the additives "plating"...We are splitting hairs of course and you will certainly not "wear out" your engine by over changing the oil. But you aren't helping it. Do a UOA and establish a baseline for your engine and usage patterns.
Also, some Race oil is formulated Without or with very low levels of detergents...Joe Gibbs has a line with low/no detergent as does Redline...That is likely why they recommend changing it out after a race weekend. It is hard to imagine the oil is "worn out" or depleted unless your engine seriously out of tune and suffering from high fuel dilution.

All great information. Nick, very much appreciate the details on all 3 of the oil lines mentioned above. In regards to the 300V does it still contain some detergents so it can be kept in for 6-12 mon depending on use or should it be changed every or every few events?
Cheers!

To be on topic, per Blackstone's recommendation I have settled on 6 track days for OCI. Engine revs to 8200rpm.

Yes, 300V has a conventional ad pack in terms of having all of the necessary detergents, dispersants, rust inhibitors etc. If you're running less than 5,000 miles/year, a 12 month interval is fine assuming driving habits are normal. This includes occasional spirited street driving, carving up backroads etc.-Nick
PS- I’ll get to your PM tonight. Sorry for the delay.

Yes, the 8100 X-power 10W60 is a fine choice for the S54 for both street and track use- it is our equivalent to the Castrol TWS 10W60 but with a higher quality base oil package and slightly more stout anti-wear package. We just picked up the Alfa Romeo/FIAT approval for road racing on this product as well.
I would also consider the 300V 20W60 Le Mans product if this is a track dedicated application. Many features and benefits vs an 8100 product -Nick
