Seafoam in oil for how many minutes or miles?

[RobPatt]

Hi,
I'm considering adding a can of seafoam to the oil before an oil change.

However, my gut says:
- NO, the engine is clean, cams looked pristine at 150K miles.
- NO, you already use Mobile 1 syn 0w40 every 5K miles...
- WHY add "gas" in the oil and jack up & thin out lubrication of bearings, etc

So, while the can says you CAN do it... I'm leaning towards NOT doing it.

Thought I'd ask you all..
Cheers,
Rob.
