STP Complete Fuel System Cleaner

[ZZman]

Silver bottle

I got a bottle on sale at Autozone. Any thoughts on how it compares to Regane or Techron?

Ingredients Concentration
Kerosene 60-80%
CAS# 64742-81-0
Naphthalene 1- 2%
CAS # 91-20-3
1,2,4 Trimethylbenzene 3-8%
(Pseudocumene)
CAS # 95-63-3
Proprietary Additive 20-40%
CAS # 91-20-3


It lists Naphthalene twice, but at different percents.

 

[ZZman]

Are these chemicals good at what they do? I suppose the
"proprietary additive" makes it hard to figure out.

 

[chevrofreak]

The "Proprietary Additive" CAS # 91-20-3 is Napthalene

Which is why I thought it odd that Naphtalene is listed twice.

Regane is way better, the stp contains too much kerosene that cause engine stumble

 

[ZZman]

Well that is not very proprietary!

Regane contains about 60% Kerosene, too.

There are better products out there like techron, SI-1, Regane.

You will have no issue useing the stp. No worries.

 

[jinx]

what is it about kerosene that makes it so bad for you engines?

 

[ZZman]

Can't be bad as almost all the fuel additive products have it in them.

Yes, but the experience of using both clearly made me choose regane.
FYI, there are 2 types of STP fuel system cleaner too, I guess the old one is better, the new one is with label as lower price, that is the one which really smell kerosene when you open the bottle and really made the engine perform poorly if you use 1 bottle in small tank.

I've tried most all of these.

Amsoil P.I. is the best IMO.

What about STP in white bottle? How good is it?
