Best,

I'm researching a few alternative filters, including some washable filters in the next week or two. I'll likely make it part of a newsletter, but I'll post my findings when ready here.

I noticed they did come out with a 5W-50 that looks to be more race oriented which should work in the 987.2 S in the summer months (I would switch back to 0W-40 for the cold Midwest winters).

They also have something call Mobil 1 Racing oil but not sure how that would work in our engines along with emissions control parts such as cats (much higher zinc levels 1850)

I have also been looking at Driven DT and DI oils as well as Motul 300V.

Finally, I too have been looking at getting the LN adaptor, Napa filter kit along with the Deep Sump. I hear mixed reviews on if these are actually needed with a stock suspension and Michelin 4S tires as I am not pulling the Gs of a car with full race suspension and with race rubber.

Interested in continuing to see what people choose especially for racing a 987.2 S.
If you want to know where the FS brand of Mobil 1 oil came out in a non oil company sponsored comparison of 200 motor oils, including racing oils that many of us use on the track, take a look at RAT/540 blog. Read it and decide what oil properties are important to you. Engine wear, high temperature distruction effects, ZDDP additives, anti foam additives, wear additives. Two products stand out, Mobil 1 FS 0W-40 and Ams 0W-30 for heat distruction and wear protection. Its important to remember that oil formulations are designed for specific needs (M97, keeping rod bearing #6 from scarring) . You would think race oil would stand out at the top of the list as that is their only job of wear protection is very difficult environments.

Then add in the cost/hassle factor of changing oil after a weekend race because that oil has limited additives staying power for street use, making a trailer almost mandatory. Add on a oil filter bullet, with 80 micron filter screen to reduce back pressure which is great for the track, not so much for daily use in my case with a M-97 motor.

This is the reason I am advocating CSF 3 front radiators, center one a GT3 with chimney, and a GT3 oil/water heat exchanger is that while running an M-97 motor, my oil wear factor, temperature and pressure margins very tight. 9A-1 engines have different needs, pistons to wall clearance is tighter, meaning the oil needs to protect the pistons from touching the cylinder walls while running at 7500 rpm and 280 degrees engine oil temps.

Hey Apex:

I've read RAT/540's blog, lots of info, difficult to navigate. I am using Motul 300V that falls in into RAT's 'Incredible' wear protection category, along with a number of other oils, including Mobile 1 'FS' 0w40. One issue with the Mobile 0w40 is, at some point, they changed the formulation; the new version was tested by RAT in 2016. When did the formulation change? The 'old' version had somewhat mediocre performance, according to RAT.

Like you, I am also looking for an engine oil that can last more than 10 hours before wearing out the additive package as I am not interested in trailering...yet. My next event, just next weekend, includes a 6 hour roundtrip drive, back-and-forth from the hotel to the track (Friday - Sunday event), so I will easily exceed 10 hours of running time.

Are you actually using the GT3 oil/heat exchanger on your car? It would be very interesting to know if this actually fits the M97 application. With regards to the CSF radiators: several race shops that prep Caymans for the track have tried CSF radiators, and while the CSF units are very well made and durable, they offer no additional cooling vs. stock, unless you upgrade to the GT3 center.


Cheers,
DJM

Thanks for your imput on the radiators, maybe I will delete the two side CSF radiators and go with OEM's there and keep the GT3 center one/chimeny. Colin Cantrell Motor Sports said he has an older GT3 oil/water exchanger on his shelf that he knows will fit my M97 application. I am in the final discussions with him to include large 2 5/8 in oil pressure, oil temp and water temp gauges that match my black backgound with white numerals in an attractive leather gauge holder on the top of the dash where the Sports Chrono wart would be. The gauge set would be rotated/positioned facing the drivers eyes.
