I need to double check but I think I'm about 127K on my 2010, 315's since 6 months new and 37's since Mar 2015.
Depends on your driving and maintenance habits I guess. I change my transmission and rear diff oil every 15k miles or sooner if I've been pushing it hard. Oil change every 6k - full synth since new. Now running high mileage synth but it's still running well.
I'm still on goal to do an LS swap so hoping the maintenance keeps it going until then. :thumb:
I maintain mine but my driving habits are not gentle ones. I'm still going strong.
exactly why I do trans and rear diff more often than required :thumb:
My 2007 has over 2000000 km. and still going strongView attachment 174224
