I spun this thread off my one I started yesterday about the 2018 GMC Terrain we are looking at that is equipped w/ 1.6L turbo-diesel. As all diesels today, it is equipped with a Diesel Particulate Filter and uses Diesel Emission Fluid. Car is for my wife. Her main driving pattern is short trips. Her work commute is particularly short @ 8 miles each way speed limits not exceeding 45mph. Her other local trips are short run around town grocery or etc., let's say 10 - 15 miles then stop, park to shop awhile, and etc. I found the following in the 2018 GMC Terrain owner manual: ------- Cleaning the DPF (Exhaust Filter) While the DPF cleaning is automatically controlled by the engine computer, the vehicle will need to operate continuously for approximately 25 minutes and at speeds greater than 50 km/h (30 mph) to clean the DPF effectively. Special DPF Driver Messages. If the vehicle is used for numerous short trips or extended slow-speed operation, the engine computer may not be able to clean the DPF effectively. If this happens, a Driver Information Center (DIC) message will display. If the vehicle continues to be driven in a manner that prevents effective DPF cleaning, the DPF will become plugged. If this occurs, the engine computer will turn on the Malfunction Indicator Lamp in the instrument cluster and a DIC message will display source: https:/
The upside of this car being a diesel is that every so often she likes to go out to East to visit her daughter and grand children. 10 hour interstate trip. This thing would shine for that sort of endeavor. Set the cruise on 80mph and let it eat. I do understand that is where diesels love to live, out on the open roads for long trips.
Just not sure this car would be right for her, trying to educate myself on diesels. Last diesel I have experience with was a 2005 Volkswagen TDI 1.9 liter. There was no DPF's or DEF back then but that VW had known issue with accumulating sludge in the intake manifold due to the way VW did diesel EGR (exhaust gas recirc) back then.
