I have a 2001 maxima , performance is not how is should be , it has 150,000 but has always be taken car of , oil chances ...etc has anybody ever used stp fuel system cleaner in there 2001 max ? And did it help ?

 

Just go with seafoam..

 

Seafoam is awful

 

Works for me...lol

 

Would using the step fuel system cleaner hurt anything , is it safe to use?

 

 

I personally haven't used stp yet but I have used gumout regain which if pretty much the same thing. anyways, from my research, the reason why furl system cleaners can be bad is that sometimes it'll unclog the buildup but the clog just moved downstream and clogs another part of the system. which has caused some serious damage to some cars. These products do what they are advertised to do, most of the time. But I will say, from the one bottle of regain I used, I couldn't seem to feel THAT much of a difference, im sure it did something though

 

Forget that STP stuff and use Techron Concentrate Plus. It's one of the very few additives that actually does what it claims and is recommended by several car manufacturers.

 

All snake oil if you ask me. Sea foam..may be the least snake oil of the bunch.

Everyone goes by their oh so reliable butt dyno and placebo effect happens.

 

Won't hurt. Won't help. Snake oil.

 

Edit....


Seafoam.....

A little more expensive but it does help. I saw that my mechanic buddy had this in his shop, so if he uses it then it's good enough for me. He said to only use it every so often, like once or twice a year.

 

Wiz said it already bud ....snake oil....

 

I use Lucas myself. I don't know how much it actually makes a difference but i trust their product.

 

gasoline is a pretty powerful cleaner itself idk how that stp stuff is going to clean anymore.
