How often can I add High Mileage to gas and oil? [SOLVED]
Asked by Keith B. In Mississippi
I have a 2007 Nissan Titan SE with 175,000 miles on it. On the High Mileage Sea Foam, how often can you add it to your gas tank? Also, can you add the oil treatment into your engine oil when you change the oil? How often can you add the High Mileage Sea Foam to your gas tank and oil?
You can add High Mileage to your fuel as frequently as you’d like. That said, once every 3,000 miles will be fine to keep your engine running strong and free from fuel-related problems. Wait until you have a low tank of fuel (1/8 tank or so), and add a whole can of High Mileage. Then, drive at least 20 miles before refueling.
In oil, add it 100-300 miles before you change your oil. That will give it time to clean, and also allow the reliquefied varnish and deposits to drain away when you change your oil.
