The 1.5 Blue dCi (K9K — the ubiquitous Renault small diesel shared across the entire Renault-Nissan-Dacia range) is the frugal long-distance Captur II choice: genuinely economical and proven. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, injector wear, the timing belt (do it on schedule), and AdBlue/SCR on these Euro 6 cars.
