 Those shorter trips might be 15, 20 miles even for this where the oil will build up. So we would suggest that. We have not had these out with a turbo four-cylinder long enough to get a good feel about changing transmission fluid when that should be. So we'd suggest keep an eye on the color of it, look at it. I'd probably say really start looking at it. I wouldn't even worry about it until you hit 30 or 40 or 50,000 miles, somewhere in there.
