Just wanted your guys' opinions. I'm heading back home from Columbus to Omaha, Nebraska later this afternoon (about 90 miles). I was planning on throwing some seafoam into the crankcase and gas tank before I leave and changing the oil tomorrow. Do you guys think that's too long of a stretch to leave the seafoam in the crankcase before I have the oil changed? I figure, it should probably clean the gunk out fairly well. Thanks in advance!

 

I have left it in for 300-400 miles before changing my oil so you will be ok.

 

I wouldnt do it, it will really think out the oil and prob do no good, Id do an Auto RX treatment if u need to clean out the engine.
