I'd have thought that would make the fuel economy worse of that were the case, and I've gotten great fuel economy with it. On the other hand, I already had the DPF replaced. Maybe I was running "too clean."
I just had both recalls done with the 30K mile service. It does feel like the car pulls more strongly at low RPM, and the fuel economy (the thing I pay very close attention to) is reduced. Though interestingly it seems that economy is actually comparatively better at a higher RPM when cruising...
I had the DPF replaced at 23K miles. My only warning was a CEL, and the notes say it was a p2002 code and a "field engineer" was on site and directed that the DPF and EGR filter be replaced. Nothing about cracking.
My previous car was a 2003 Mazda Protege5, and while I liked it as a car, it got terrible fuel economy for a 4-cylinder, and when I was looking to replace it I wanted something more fuel efficiant, but wasn't willing to get a very small car. The top contenders were the Mazda3 SkyActiv, the...
Sometimes drafting can hurt you by making you accelerate at the wrong places to keep close.
I might get another 800 on this tank, but I can't see 900 even on the horizon. I am amazed at how much work this must have taken.
I'm not sure I get the concept. The problem with city driving is the time spent idling at lights and waiting for other traffic to get up to get moving, not the gearing. If you really want a city car, I'd recommend a hybrid, or maybe one of those micro cars like the new Mitsubishi Mirage.
