I just seafoamed my car by letting the vacuum line suck it into the throttle body.

I'm trying to think if there would be any reason that would call for the oil to be changed. I believe all the passages that the Seafoam comes into contact with would not really access the engine oil at all.

Any thoughts?

I vote no.

Unless you put some in the oil there should be no reason to, if it goes into the throttle body the engine will treat it just like gasoline and burn it all up, should be no contact with oil unless you've got other problems (rings, cylinders, etc.)

 

Those were my thoughts as well.

Oh yeah, I forgot to mention that the car does idle smoother than before the Seafoam. It was good before, but even better now. It's running very smooth tonight. The seafoam helped a little. It is a little embarassing having all the smoke come from the car. I'm just glad it was windy here today, so it didn't linger at all. When I drove it, before the smoke was gone, I'm sure people thought my car was jacked up.

I'm replacing the O2's this week anyways, so I figured that this would be a good time to try this, before I change out the O2's.
