STP Complete Fuel System Cleaner

Is STP Complete Fuel System Cleaner worth using?

 

[autoapprentice]

I believe so. I like STP products. Pretty much anything will be beneficial though. STP, Valvoline, Gumout, etc.

The common recommendation here is to use a cleaner with PEA. Not sure if the STP cleaner has this ingredient or not???

Just got Techron bogof @ O’R’s … but needed both since they just do 12 gallons per bottle

Yes, the STP Complete Fuel System Cleaner does contain PEA

 

[AutoMechanic]

I use Gumout with PEA it works good. Never tried the STP stuff. Liqui Moly makes some great fuel system cleaner as well. And Techron is also good.

I like STP the silver bottle

 

[wdn]

I use Lucas Deep Clean

STP Complete Fuel System Cleaner does not list PEA as a substance on the safety data sheet. It does list three kinds of kerosene, napthalene and various petroleum distillates. Solvent based cleanere work too though.

 

[JT20]

Gumout with Regane (PEA) or the All-In-One
Or Redline SI-1.
MAYBE Royal Purple MaxClean (costs a lot, like SI-1.)

Don't even bother with anything else.

 

[jimbrewer]

When I looked into it, Redline offered the biggest one-shot dose of PEA, although not at a low price.

Maybe the most cost effective thing is to get a multi-pack of Techron and run it through successive tanks of gas.

Some of these fuel system cleaners are heavy on naphtha more than PEA. Not necessarily horrible, but I wouldn’t pay much money for it.
The version of STP I used had a token (5%) amount of PEA in it.

I have had good to great results using Royal Purple Max Clean. I like the fact that it can be used in a gas or diesel engine, good for up to 10,000 miles, and treats up to 20 gallons of fuel at a time. I was a big Seafoam fan before using this stuff.

I find it strange that people perceive this as being an expensive product yet some will be spending more buying multiple bottles of whatever product to use over the course of the 10,000 miles RP Max Clean is rated for.

 

[wdn]

The Lucas Deep Clean has the same concentration of PEA listed as the Gumout All-In-One. However the Lucas bottle is 16 ounces vs the Gumout is 10 ounces or 6 ounces. Either will do the same thing.

What's PEA?

attached STP bottle photos

 

[wdn]

PEA is polyetheramine, a detergent compound trademarked as Techron. It is used in many fuel system cleaners and is also a gasoline additive.

The last time I got gas, it was at a Rutters, which is a chain here in Pennsylvania (maybe other nearby states also, but never seen it anywhere but Pa.) Rutters recently became a Top Tier fuel. When I filled up the other day I noticed on the pump that it said something about the fuel system cleaner being STP. I have never seen that before on any gas pump.
