Are the Fuel Injectors in the Cl-S self cleaning?? j/w thanx alot!

 

i dont think so, i add the stp fuel injector cleaner every oil change just to be safe

 

is valvoline any good?

 

All the mojar gas brands put detergents into their gas.
But I also put a bottle of injector cleaner every now and again.

If you use high octane stuff like Sunoco 260 and the 93-94 Octane stuff, you're okay. STP gas treatment is a good secondary one though.

 

how about ZMAX and all those other infomercials? anyone used those?

 

agreed...i cycle between the STP in the black bottle and the complete fuel system cleaner in the grey upgraded-looking bottle

 

Last I heard they were getting Investigated for Fraud, that their product does absolutely nothing for the car. I tried it once on my old car and I noticed nothing.

I just use Valvoline and Amoco Gold Gas, they havea detergent I hear.

 

Different brands of gas use different additives/detergents.

I switch my brand of gas every 2 months. Texaco and Crown. The idea is Texaco will clean out what Crown does not, and vise versa.
