Recently, I started a thread about adding a bottle of Regane 2x High Mileage Fuel System Cleaner to my friend's 2010 Mazda 3 Touring with 12.5k. A few people in the thread claimed it was too early, and I should wait longer. Many fuel additive companies recommend adding their product every 3,000 miles, but it is quite possible for them to have some ulterior motives.
For me, I have been adding a fuel system cleaner every 15k or annually, whichever comes first. How often do you folks add a fuel system cleaner?
Thanks.
