I run regular gas in my stock '06 4.7. Should I add fuel system/injector cleaner? If so, how often?

Thanks for your opinions....

 

I use Sea Foam at oil change time, which is 5000 miles or basically yearly for me. I'll wait till I have about half a tank, maybe a little more and pour a 16 oz. bottle in.

The Chevron Gas Treatment with Techron is another product that consistently gets good marks from most performance shops...

 

Thanks, Hammer.

 

I use the lucas fuel injector cleaner additive. Usually once every two months.

 

I usually run sea foam every three oil changes. Half in gas tank and about a quarter through brake booster.

 

I have had good results with the Techron too.
We had a high sulfur gas issue here a couple of years ago at our Speedway stores (Marathon owned). It killed pumps and soiled the sending units. Techron was the best product that I used on other peoples cars and trucks ( I never use there gas) to clean the crap out of the fuel systems. Worked good. Saved all but one sending unit.
I'm sold on the stuff.

 

Thanks for all the replies...

 

Techron is buy one get one at advance right now.
