Between Liqui Moly & Chevron Techron, which fuel injector cleaning brand performs best? Do they both have equal strengths or are there other brands outside those two that work better?
Honestly, just get the Techron or STP fuel cleaner. Most are either snake oil or a similar blend anyway. Realize that if you need a fuel injector cleaning, those additives may not help anyway.
In fact, if you are using Chevron fuel, it already has Techron in it and adding an bottle isn't going to help. But if you want to give it a shot, Techron or STP would be my recommendation.
Shell also has something similar in their gas.
Shell has V-Power, which is the best in my opinion. But they do not sell it in bottle form as far as I know. The Nitro blend they have in their premium fuel burns awesome in performance engines, I can tell you that.
Chevron, Shell, and STP are the ones that you want. I wouldn't bother with Liqui Moly.
I've used Berryman B 12 with good results,
