Is a large increase in fuel consumption a sign of the DPF regenerating?
My 2016 Toyota Yaris diesel fuel consumption meter indicates a large increase in consumption for about 25 minutes every 350-400 miles. Is this the DPF regenerating?

Yes. Definitely. As long as the oil level in your engine is not rising the system is working properly. If the oil level is rising, then the extra fuel used is not regenerating the DPF and instead is sinking into the engine sump.

More room and better handling than the previous version. Excellent crash test rating. 1.4 D-4D does 50mpg +.
