SUMMARY
Sea Foam Motor Treatment can be used in every type of gasoline or diesel engine. When added to an engine’s oil crankcase, Sea Foam Motor Treatment works to clean and liquefy heavier oil deposits, so the residues will drain away when the oil is changed. Sea Foam cleans internal engine parts, prevents sludge and other harmful oil formations.

Can Sea Foam be put into motor of a Nissan Murano 2014 awd?
Thanks for the question!
Yes, you can use Sea Foam Motor Treatment in your 2014 Nissan Murano. Just follow the directions on the can.
Here’s a little more info on how to use it:
- Sea Foam Motor Treatment in fuel. I like to wait until the tank is low (1/4 -1/8 tank), add the whole 16 oz can, and then drive for at least 10-20 miles before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits.
- Sea Foam Motor Treatment in oil. Add 1 ounce 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, and it allows all the reliquefied oil residues to be drained away with the old oil.
How many times can you put Sea Foam Motor Treatment in your oil between oil changes?
Thanks for the question! You can only put Sea Foam in your oil one time in between oil changes. Add 1 ounce of Sea Foam per quart of oil in the crankcase. Do not exceed this ratio.
The Sea Foam will work to clean and lubricate the entire time it’s in the oil. The recommended ratio is sufficient to clean. If you’re looking to get the most cleaning potential out of using Sea Foam, add it in between every oil change and it will progressively clean away oil residues and deposits.
Can I just let my car run for 15 minutes after adding Sea Foam or do I have to drive it?
Thanks for the question!
For Sea Foam in the oil crankcase: it’s best to drive it for at least 100 miles to give the Sea Foam a chance to circulate and clean. Running it for 15 minutes is better than nothing, but driving is the best way to get the most out of the Sea Foam.
Can I use Sea Foam in my Packard 8 1936 1400 120?
Thanks for the question, Richard! Yes, you can use Sea Foam in your Packard. It’s made with petroleum ingredients that won’t harm anything and work well to clean fuel residues and varnish.
Here are a few recommendations on how to use it:
- Sea Foam Motor Treatment in fuel. I like to wait until the tank is low (2-4 gallons), add the whole 16 oz can, and then drive for at least 10-20 miles before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits.
- Sea Foam Motor Treatment in oil. Add 1 ounce 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, and it allows all the reliquefied oil residues to be drained away with the old oil.
If it’s sitting for any length of time, you can add Sea Foam to every tank to prevent the fuel from degrading and gum and varnish from forming while it’s in storage.
When adding Sea Foam to crankcase oil, is it ok for me to take a while to get to 100-200 miles? I don’t drive my truck much and it might take a month to get there.
