2011 Chevrolet Volt: Breaking in the Engine

So how do you break in the engine on your new 2011 Chevrolet Volt? According to the owner's manual, "The vehicle does not require a break-in period. Vehicle break-in is performed during manufacturing." But we are creatures of habit.

For the past week we've been running the Volt on the gasoline engine only. We depleted the battery fully and hit the road. It still isn't only running the engine, though. In some situations, such as accelerating from a stop, the batteries kick in to get you going before the gas engine takes the reins again. At this point, you're finally putting miles on the engine.

Speaking of the engine, you'll know when it's running because the 1.4-liter 4-cylinder is loud. But after a couple of tanks averaging about 39 mpg, it also seems to be efficient. More to come on tracking our fuel economy later.
