I was a rural mailcarrier for 30 years so I have had my share of cars. Very interested in the Smart engine. Does it come from the factory with synthetic motor oil? Also does the transmission come with synthetic fluid? As far as gas does the owners manual state that you must burn premium fuel?
Here in Iowa we get 3 grades of fuel. 87 octane,89 octane-which is ethanol,and 93 octane. Can the Smart motor burn the ethanol ? Also what mileage should you give the engine for the break-in period? I bought a brand new 2000 Neon and right at the 8,000 mile mark the gas mileage improved 4-6 mpg. I really do believe that you should break-in a new engine the proper way.
2 of my route cars were the Dodge Spirit with the 2.5L 4cyl. and the 3.0L 6cyl. I broke them both in and both of them only started burning oil at the 185,000 mile mark. After that when I would change the oil I would use a quart of Lucas oil treatment and sold both cars with 215,000 miles on them. Not bad.
