How much Sea Foam do I pour in the oil crank case of my 2014 KIA Sportage xl? [SOLVED]

Thanks for the question! Add 1 oz of Sea Foam per quart of oil in the crankcase.

We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean. It also lets you drain away all the reliquefied crud (residues and deposits) when you change your oil.
