SS has 114k and got the seafoam treatment. Smoked like a forest was on fire and seems to run so much better. Even did the oil but only put about 40 miles on it and changed it. Will drive it all this week and do another oil change next weekend.

So you keep it in the engine oil, for a few miles?

Most people run it in the oil for 100-200 miles, then change the oil. You don't want to go too long before changing the oil, as the seafoam usually turns the oil into tar (very black, and thick).

If you have any other questions, I suggest you read through this thread:

I do it to my car once a year. Fuel tank and booster only. I can't seem to dump it in my oil. Need to do it to my truck. It definitely helps.
