Agreed!!! Lets be clear for everyone else...
In general, a well running EGR system in a GASOLINE engine can have secondary positive impact on fuel economy, in addition to its primary job of reduced emissions.
Also, in general, a well running EGR system in a DIESEL engine can have secondary negative impact to fuel econnomy, while perfroming its primary job of reduced emissions.
Hence, diesel owners that may do an EGR delete to improve FE and performance (at a cost in emissions), and gasoline owners (and Ford and Mazda) looking to do an EGR add to improve FE on gasoline engines.
