Personally, I use a bottle of Chevron Techron fuel additive every month in my 2002 Chevy Silverado and my wife’s 2025 Nissan Rogue. I buy the high mileage version for my truck and the regular one for her vehicle. I have them on “Subscribe and Save” with other items on Amazon.

I started this about a year ago and noticed a big difference in my truck. I wish I had done this from the very beginning like I am my wife’s vehicle.

Don't use any. I try to use nothing but Costco gas. It is a top tier brand and have never had any problems with them. Plan all my trips in advance and know where their gas stations are.

The best way to keep the fuel system clean is regular purchases of Top Tier Plus fuel. The series of engine tests required to earn the credential is comprehensive and technically sound.

This is the best answer, and really not that hard to achieve at nominal incremental cost unless you're addicted to chasing the very cheapest/shittiest gas to save $47/year (looking at you, Georgeair's sister!)

Top Tier
They've even added a detailed search feature so beyond just major brands you can find ones local to you.

they have an iPhone and Android app too. The iPhone version let's you choose gasoline and/or diesel then gives you a list of top-tier stations by distance.

Techron and BG44k are the only ones worth using imo
