If this was really a problem, why do car engines last so long on plain old E10? I can't imagine many people are adding ValvTect every time they fill up. I certainly don't witness it at gas stations.
My commuter car has 192k miles, runs perfectly, and has never seen a drop of any gasoline additive. I'd estimate it has at least 4800 hours on it (assuming a 40 MPH average speed over the life of the car).
I would think the cold Winter start-ups the car has to endure would exacerbate the issue compared to the typical warm temperature a Winnipesaukee boat is going to enjoy at start up. My boat engine is probably already at least 65 degrees when I first start it up most days. It's never been started below 32 degrees. Yet, even though the car gets most of it's starts in cold weather (I ride a motorcycle when weather permits) it still works fine.
