They are kind of different in uses and would depend on what you need. Seafoam is much better for trouble components that need a quick flush but isn't a long term prevention/cleaner. Seafoam works best in those cases by doing a direct soak then flush and finally do an oil change. Liqui moly is more of a maintenance additive and will clear out minor carbon through time. This is more for newer engines with lower mileage and helps for city and/or short distance low speed drivers. Personally, I think redline is better for cleaning and flush for an additive type. Full system flush I am still a fan of bg and saw what it does when I was a tech but it requires the tool setup.

Strartron. Thank me later. Best bag for buck engine cleaner. Extra concentrated of the diesel formula is most cost effective.

Gonna try this on my 2020 Accord (2.0 turbo GDI) and my old RX-7, because I like clean valves. 🙃

Liqui Moly : 80-100% naptha
Star Tron : 95% naptha
SeaFoam : 25-35% naptha, 40-60% pale oil
Liqui Moly and StarTron are better at fuel preservation and cleaning the intake path.
Seafoam is more multi-purpose. In addition to fuel preservation and cleaning the intake path, you can safely run it in your oil before an oil change. Ideally you should never have to do this. Run good oil and keep it clean. But if you have high mileage engine that lived a life of neglect, it really can help extend the time before an eventual rebuild.

Won't clean the intake valves on your accord. Direct injection bypasses the intake valves completely. This product is mainly for port injection engines.

Not for you. They can clean the injectors on a DI engine, but not the valves.

MORE benefit for port injected engines (HEMI, LS1-9, Pentastar, etc).

For DI engines I run one bottle a tank before the oil change. Kia and Hyundai made this a recommendation long after I started doing it with my DI engine.
