I took my RC350 in for its 35K service and I was expecting them to change to oil and the dealer said they only do it every 10K. Up until now they had been doing it every 5K. Even on synthetic 10K seems like a long time to go between oil changes. How often does everyone else change their oil on these cars?

Every 5-8K. 10K seems a bit much for me. Every 3K like the oil change places say, that's just bullshit.
Waste of time, material, and money. I've done 8K on my 96 GMC, just like manual says. Over 200K and
still kickin". Synthetic in it since new.

Usually at 5k miles here as well on synthetics.
