When can I add Sea Foam to gas and oil? [SOLVED]

I just had my oil changed in my 2014 Toyota Corolla it has over 200k miles. My vehicle has started to act sluggish and it doesn’t sound as quiet at start up. Is it okay for me to add the Sea Foam Motor Treatment to my crankcase and gas tank?

Thanks for the question, Meyoshi.

In fuel, you can add Sea Foam Motor Treatment at any time. I like to add a full can to a low tank of fuel (1/4-1/8 of a tank) and drive for at least 20 miles before refueling. That creates a high cleaning concentration of Sea Foam and gives it time to clean. It’s one of the best and most efficient ways to use it!

In oil, we recommend adding it 100-300 miles before your next oil change. Add 1 oz per quart of oil.

Hope that helps!

Should I add Sea Foam to my gas and oil at the same time? If not how far apart? Which first?
