I know this question has been asked about engine rebuilds but what do you guys do relative to the shorter service interval maintenance (oil, filter & drive shaft)?  I'll be going to the track next week and have 4.9 hours run time and 2.6 hours load time on my new SR10.  I anticipate after 2 days I will be at 6.7 hours run time and 4.5 hours load time.

 

The service interval is 6 hours so I'll be a little over on run time but not load time.  Should I take care of it before going to the track or do it after?

Hi Clark (@clark-darrah), I don’t have any first hand experience with the SR 10 but I can tell you that with the 1500 in my SR3 I always had an oil analysis done at every oil change and the results always came back saying that the engine had plenty of life and change intervals could be extended. I pushed my intervals out to 10 hours with good results. The oil reports stil said I could extend further but I am conservative and kept it at 10 hours.

Hi Clark.  I plan to be at VIR next week also with my SR3.  Looks like we could see some rain.  I'll be in one of the pit lane garages -- let me know if I can help you with anything.  See you soon.

Thanks, Charley.  That's kind of what I figured.  I don't mind doing the work but also don't want to unnecessarily turn 6 hour maintenance intervals into essentially 4 hour intervals.

 

David - I'll definitely come by.  Hopefully the rain holds off!

I have gotten into habit of changing engine oil and GDU every other HPDE weekend (4 track days with 4 sessions each).  Depending on the weekends, rain, missed sessions, etc - this can possible extend to 3 weekends.  I used to do the same on my Porsche race car.  Personally, I think it is excessive as fluids look almost new and as Charley said, test that way as well.
