Do these actually work? What is Veeky Forums's collective experience with fuel cleaners?

I tried a can of seafoam and a can of b12 and neither made a noticeable difference, and my shitbox has 300k miles so there should be some shit to clean.

seafoam down the intake made a difference though.

Techron or riot. My old man worked for Marco and that was the only thing the engineers actually put any stock into for fuel system cleaning.

i worked in a shop for years, SeaFoam does fuckall. my boss would call for it to make money, i liked it because i could dogfuck 45 minutes blowing smoke out of the exhaust cracking $35 an hour

i use Gum carb medic in my Subaru Sambar because for $5 even if it doesnt clean the carb so be it. truth is pump gas has so many detergents as it is you dont need aftermarket crap

>fuel cleaners

just follow scottys wise words and you'll be fine

Seafoam down the intake stopped my valve train clatter.

Think it could help with lifters? I hear ticking for the first 1.5 seconds as the engine starts

Nah, that's all engine oil. You could dump it in the oil I guess.

They work marginally if you use them regularly. Really you should just be using better fuel.

I've already tried rislone but it didn't really help. Also it only happens when the engine is cold, start is smooth and quiet when the engine is warm.
