Is Sea Foam Motor Treatment good for a 2014 Mazda 6 and a 2014 Nissan Sentra? [SOLVED]

Thanks for the question!

Yes, Sea Foam would be helpful for them both. Here’s why. When added to your gas tank, Sea Foam Motor Treatment works to clean and lubricate the entire fuel system (fuel injectors, upper cylinders, etc.). It cleans residues and deposits that form in any engine over time, and are often the cause of engine problems like rough idle, loss of power, and hesitation. Adding Sea Foam to your gas tank will help overcome or prevent these problems. It’s made with 100% safe petroleum cleaning and lubricating ingredients so it would work in both your Nissan and your Mazda.

Here’s what I like to do: wait until you’ve got a low tank of fuel (1/8 tank or less). Then, add a full can of Sea Foam to the gas tank. Drive until almost empty before refueling with fresh fuel. The high concentration will do a great job cleaning. We recommend doing this every 3,000 miles or so to keep your engines running clean.

Hope that helps and let us know if you have any other questions!
