30K service. New coolant, P/S fluid , Trans fluid , syn oil. And fabricated side exit exhaust.
P.S. 5W/40 is the secret to stop smokong turbo's. Its part of a dealer TSB.
been doing this since day 1 with the speed6 and now I fully plan on doing the same thing with the speed3

5w40 huh? tell me more
Here's a little blurb taken from Mazda6 forums:
"The theory behind the smoking issue is that at idle, the PCV does not allow enough vacuum to escape from the crankcase and the pressure overcomes the the oil return to push back on the turbo seals. This predominately happens when you reduce backpressure on the exhaust."
running the thicker oil fixes this issue....
