What oil in the 6GT3 for Track Use?
OK I don't want to start an oil thread...but I am starting an oil thread. I just sold my 996 C2 and bought a 6-GT3. On the C2 I ran Joe Gibbs XP9 racing oil as recommended for the fragile M96 with it's crappy oil pumps. I would love to not spend $250 in oil for 500 miles of oil life on my 6-GT3 like I did on the C2, but if I have to then I will.
So...what oil is generally used on the 6-GT3 for track use? Previous owner was using Liqui-Moly 5w-40.
Thanks in advance.

Porsche A40 approved Mobil 5W50 would be a good selection. Easy to find at Napa. On sale about 4 times a year at $6.

Dougherty Automotive in West Chester PA pinned the coolant lines in mine and did a bunch of did other work. They use Motul 5W40 8100 XCESS. From Bill Dougherty:
"We run MOTUL 5W40 XCESS in all the Porsche water cooled engines. It meets the Porsche A40 factory approval. We and a lot of Porsche specialists prefer it over the MOBIL1 0W40 especially for track use."
I have no idea why they say they prefer it for track use and personally I don't know enough to have a preference. I've always used Mobil 1 in my vehicles so the GT3 is the first one that has something else.
So far I have about 2K miles on this oil, 3 track events. Car hasn't burned a drop as near as I can tell. Can't see the oil on the dipstick so I don't know what it looks like though.
And hey Nick - I also have a '64 Spyder convertible! ... it was bought new and owned by the astronomer Carl Sagan.
Sagan bought a Porsche 914 after he had the Corvair and he had the license plate "Phobos" on that Porsche, so I got it for the Corvair.
When I got the GT3 the choice for that was simple!

Thanks for the oil advice to all who responded.

Root....I have seen photos of the Sagan Spyder restoration online...I also did a full rotisserie restoration on mine (you have probably seen it on CCF, my restoration thread has over 60,000 page views). I am certain you and I own the most expensive Corvairs in history as mine was as big of a money pit restoration as yours! Very cool that we both own 6-GT3's too.

You'll get less of an oil debate here but you'll still get some.
I use Motul 300v in 5w-40 weight. The Motul 8100 would also be an excellent choice I use that in all of my high performance cars other than the GT3

I've been running Motul Sport 5W50 with good results as shown by Blackstone reports. Wear metals improved vs Mobil 0W40, mixed use street/track with plenty of hard miles/DEs/road trips (19k miles in 14 months!).
Based upon my discussions with a several Motul reps while I was retailing their fluids at a Porsche shop--the Sport line blends the benefits of the 300V race fluids with considerations given to a street formulation (longer oil change intervals, cold start protection, detergents, etc) that aren't part of the race oil package. 300V line is as good as it gets for a full track/race car, but I drive my car often on the street and 300V contains few detergents and is intended to be changed often. The 8100 line, while great for street cars (and probably more than adequate for track use, too) has inferior high-temp/high-shear properties to the Sport and 300V.
I change oil every 4k mi which typically includes a couple DEs and street miles. For dual purpose use, the Sport 5W50 made sense. BUT--it's not easy to find and more expensive than the Mobil options. I see it available on Amazon @ ~$70/5L (or $14/L). If your 6GT3 is a dedicated track car, I would go 300V. And regardless of what you're using, as long as it's Mobil 0W40, 5W50, Joe Gibbs, Liqui Moly, etc and you're changing it often, you should be okay--there will always be a debate and anyone with an opinion has a side, whether fact-based or otherwise.

This is a good interpretation of our Porsche products line with one slight difference. 300V has a very stout ad pack for detergents, dispersants etc. It’s the group 5 ester synthetic molecule that can become unstable after long drain use vs conventional synthetics- really the only drawback of esters. They will outperform in every other way however. 8100 and Sport are great products for mixed driving (street and race) and even 300V if you don’t mind spending the extra cash and keep the intervals down to around 5000 miles to start.
Let me know how I can help bring anymore level of understanding of Motul oils and how wecan benefit your Porsche -Nick

What is the oil change interval on the 300v with track use?
#14
on a real race car we change after each race (300V 15w50). we're doing an oil analysis after each race...
On a trackday car (with 300V 15w50) I'm doing it after the season (depends on the number of trackdays). for proper suggestion you need to do an oil analysis

I'm changing 300v after every 6 days on track (500-700 miles depending on events). Oil analysis says i can go longer but I'm stuck in my ways of making sure it's always got fresh fluids.
