He said that he would highly recommend me paying for an additional oil change in between at 5k intervals if I am planning on keeping the car and i want to be in great shape
I will allow him to use the bmw oil even though i hear it can sludge earlier than Castrol, i mentioned this sludge factor and he said 'that's why I said to do it every 5k'
Lets see what happens, I'm not so sure I feel like showing up to my oil change appt with bags of my own castrol oil either...
Which dealer do you use? I just did my break in service at the dealer.
I may go independent for off cycle oil changes and bring bags of 0W-30
