So my Cruze TD has about 55,000 miles on it now, and has been mildly trouble-free. I've had several emissions-related trouble codes, as well as the annoying "Poor Quality DEF" light come on multiple times. Being somewhat technical minded, and after perusing several delete threads, I've decided to give it a go, with the intentions of paying now to save later. I plan on keeping this car for at least another 5 years, well past the warranty, and would like to knock out the very expensive emissions system that has the potential to be a ticking time bomb. Also, I am not a big fan of other people telling me what I can\cannot put on my car, so doing this feeds my Libertarian leanings .
I've had the car for almost a year, but lost my mileage records in August, and had to start over again. Since then, my average MPH has been 39 MPH.
So far, the car is averaging 38 MPG in a mix of winter and summer blend diesel, lots of city driving (lowest MPG for a tank is 26, highest was 53), and a few long trips mixed in. I run AMSOIL for the motor oil, and will be switching the transmission fluid out to AMSOIL soon, too.
Total cost with the military discount on the Oz Tuner\new down pipe was $1227.60. I decided against the EGR block kit, since they shut the EGR off in the tune. As often and as best I can, I will update this thread with new results.
