I'm reading the basic maintenance procedures on the STP site and they say you should there Gas Treatment every fill-up and there Fuel Injector Cleaner every other fill-up. They also say to use there Complete Fuel System cleaner twice a year and Super Fuel Concentrator Cleaner every oil change...

My question is, do any of yall reccomend actually following all those procedures or is this just a money scheme? Has anybody actually tried doing this maintenance and did it actually help any at all?

Discus...

 

I used their gas treatment for a while (got a free t-shirt out of the deal ) but I didn't see much if any difference. I think its just a scheme.

 

Scheme, once in a while but i dont follow it like that regularly
