I just changed my oil (Mobil 1). I have a half can of seafoam left over from when I poured the other half in the old oil about 500-1,000 miles ago. My question is simply this:

Pour the other half in the new crankcase? If so, do I need to drain any oil if it's pretty much topped off?

OR

Pour the rest in my gas tank which Im gonna fill up to 3/4 tomorrow?

 

half in a vac line half in gas, after u do vac line let sit for 5-10 min then start and watch ur jeep smoke as it cleans out ur vac lines

 

The vac line is the one runnin from the brake booster to the intake manifold isnt it? Cant you just pour it in the throttle body?
