Does this stuff in a can actually do anything?Is there a really good brand out there to use hopefully available in canada too. I have around 62,000 miles should i need some? I just like to baby my truck and keep it running really well.

I use Sea Foam. Man that shit STINKS when burning out exhaust. :eek:

use marvel mystery oil per instructions on the bottle. best injector cleaner i have used other then the proffessional type you need special tools for.

i run lucas oil products in everything in my truck, and have no complaints whatsoever.

does everyone think they really clean the injectors?

it isn't just injectors, it's the fuel system as a whole. and i think to an extent, yes they do.

they do, cleans the valves and tops of pistons also. I did an intake on a friends car he used marvel mystery oil religiously. the inside of the intake ports and the valves i could see were spotless. i have seen a lot of engines but never one this clean it had well over 100k on it. some of them the valves are so clogged with carbon you couldnt even see them.
