Here is a video I found : Not sure if I would use it on my MY85 but interesting.
Unless someone else has another proven method to clean I would be interested.
Let the games begin ! lol

Sustained aggressive driving will clean up the carbon, stop and go creates it.

Did the Sea Foam do the cleaning or the recommendation of the aggressive drive after using it?

I've had the opportunity to pull the heads off many of the turbo volvos the family drives, we have one with 360k km, less carbon than the Honda after treatment. The car gets it's share of highway trips.

Also the aggressive highway ride is a lot more fun

I did not see any appreciable decrease in carbon, not enough to make it worth the cost of SeaFoam or the time to do this. Use quality gasoline, keep your car well tuned and you will get good performance and longevity out of your engine. I am more interested in how the valves look after any treatment. That, to me, is more important. Carbon on the piston, unless it's excessive, creates a slightly higher CR. YMMV

All i saw saw a waste of his time.

You could create a drinking game where you need to take a shot every time he says "Carbon" and you'd be plowed within 90 seconds.

Seafoam...For those who prefer their piston crud to be white, not black.

I'm pretty sure the point of this video was to chirp the tires in second gear--for a legitimate cause, of course.

What a huge waste of time.

That is what I thought, just wanted some reactions. I would be more interested in the valves also and the injectors.
