Long story short, it loosened a lot of garbage and sent it to the filter, which is what we want. But I'd probably only run it for maybe a thousand miles at a time. Maybe do that a few cycles with a cheaper dino oil.
tsk tsk tsk. I bet the oil you took out of there was thicker then gear oil. You shouldn't have driven it more then 100-200 miles tops with seafoam, you were just asking for trouble.

Sorry to say, you've heard wrong. All that smoke produced with seafoam is cleared carbon build-up. It stabilizes idle, cleans the injectors, and it has personally given me improved gas mileage.
