Anyother recommended brands that arent too expensive, but will give the same results and are around the same prive range?? (ive seen other brands like prestone for like 75 a bottle but i dont trust putting that stuff into my engine. And i heard of bg44 or something like that but seems to costly for me.)
It sounds like you're treating this injector cleaner as a much bigger deal than it is. It's the kind of thing you would do as an afterthought when you buy a tank of gas, not plan on six months in advance. The reason I say that is because I've used various cleaners several times and have never noticed much of a difference (nor have they caused any damage), but I still think they might be worth the $6 every now and then.
