I used a bottle of Sea Foam Motor Treatment and it has improved my rough idle and stalling but not completely. Can I use another bottle right away? [SOLVED[

Thanks for the question!

Yes, you can use another treatment right away. I’d recommend High Mileage Sea Foam since it’s formulated to be a strong cleaner for stubborn fuel residues and deposits. Here’s what I’d do:

• Wait until the tank is low (about 1/4 tank or less)
• Add a full 16 oz can of High Mileage
• Drive at least 10–20 miles (or until nearly empty) before refueling

The high concentration works much better and faster to clean fuel residues and deposits than adding the same amount to a full tank.

If deposits are causing the remaining rough idle and stalling, another high-concentration cleaning treatment should help. If the problem continues after cleaning, there may be another mechanical or ignition issue that needs to be checked.
