hello people, who has more precise infos like the diesel engine in the new smart II gets his oil changed? the gasoline engines should come from mitsubishi and there is the drain screw. the diesel engine comes modified again by merzedes and I swant evils. hopefully there is an oil drain screw for the cdi and hopefully the service intervals are more extended. the first diesels were all 12.500 km invited to the service, then later the service intervals b with 10,000 km. I would look forward to your inputs. thank you!
