I see most everyone on 986 platform using 10W30 or 10W40. Should I move away from the factory 0W40 for track use on this engine? My newer 911s (both Carrera S and GT3) did fine with track use on 0W40 but those engines are very different from a 20 year old M96, so I am not going to assume that the same "just works" here too  |
The XP-9 is only good for 750 miles from what I have seen, and so that wouldn't work for me since I drive to/from the track, in some cases I exceed that mileage before the weekend is up, if the track is far. If you are trailering and just driving track miles, I guess you would be able to get more than 1 weekend out of it. The folks I know running it seem to like it and they all trailer their (dedicated track) cars.
In my Boxster (2000 S) I went with Millers Nano after reading their 996 race car case study, I ran their 5W40 first and then went with their 10W50. I was able to get 4,000+ miles out of the oi (combo of highway driving + track, if I was trailering the car I would not attempt to get 4000 track miles), supported by UOA. So that helped offset the cost for me since the Millers is pricy
I went to 10W50 from the 5W40 because it seemed to perform better when hot with regard to oil pressure, but I don't have any hard data to back that up, just a notion from checking the oil pressure/temp gauges that I had positioned within the camera view.
In my Cayman I am running Motul 5W40 sport, which is an Ester based synthetic that is positioned between their 5W40 x-cess and the 300-V track only oil. I have gotten good UOA out of that and target a 4,000 mile interval, again with a combo of highway driving to/from track days.
Yes to a track video forum and cool videos in this thread, thanks for sharing! Track exchange hosting sounds good but I wouldn't want to drive anyone else's car or let them drive mine, what if it chooses that day to blow up
I would feel bad
