Thanks for the question, Lester! Yes, you can add Sea Foam to the oil of a small engine like a lawn tractor. Add 1 ounce of Sea Foam per quart of oil. We recommend adding it shortly before an oil change. Just make sure to run the tractor for a few hours with the Sea Foam in it before you change the oil. That gives the Sea Foam a chance to circulate and clean.

Thanks for the question, Joe! Add one ounce of Sea Foam per quart of oil in the crankcase. That adds up to 5 ounces of Sea Foam in the oil crankcase of your Mazda 6.

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 (oil residues and deposits) when you change your oil.

Thanks for the question! Yes, you can add Sea Foam Motor Treatment to your CAT 3208’s crankcase. Add 1 ounce of Sea Foam per quart of oil. That comes out to 24 oz of Sea Foam (4 quarts in a gallon x 6 gallons).

Thanks for the question! It’s safe to leave Sea Foam in the oil for as long as you’d like. That said, 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. Add 1 oz of Sea Foam per quart of oil in the crankcase. Do not exceed this ratio.
