Lighten up on him. It depends on whether, when he DOES drive it, if it gets up to operating temp long enough for contaminants to vaporize off.

I don't change the oil in my vehicles until it either looks like it needs it, or in the case of daily drivers, 5 to 7k miles has passed. It just occurred to me that I haven't changed the oil in my '59 since 2000! But I check it frequently and gosh darn, it still looks honey-colored on the dipstick. That's cuz when I do run it, I run it long enough to get it nice and hot.

Oh... and in 30 years of motoring, I can't think of any instances of suffering any sludge-related problems due to my oil changing practices.
