I have 30,000 miles and so far change the oil with Castrol Syntec whenever the car tells me to. I have already changed the MN-6 fluid with Amsoil and the REAR with Royal Purple. What should I be on the look out fro next? The breaks need to be flushed? Cooling? Anything else need to be maintained above and beyond what is in the owners' manual? Oh, yeak, I do have a new fuel pump (warrenty) and the fuel filter was changed at 28,000 miles, so that is good, too. Any suggestions as to what to look for now? Thanks in advance.

OH yeah, aside from the friggin' annoying pinging, my car seems to be fine as of now. Now, if i only hadn't destroyed that MAF screen getting it out

i'm in almost exactly the same place as u.
i have nearly 38,000 though, and have replaced fuel filter, oil changes, rear diff, and tranny fluid.

also changed spark plugs and wires...used ngk plugs/msd wires

next up is the tranny fluid again, then the brakes. I'll at least have them checked. maybe have the fluid flushed, too. good luck

 

The fuel filter gets dirty pretty quick. I think it's good to change it every 10,000 to 12,000 miles. I don't think you need to change the transmission fluid very often on an M6 car.
