How often if at all do you guys use this? The ones that come in a little bottle and you pour it into the gas tank and you are suppoesd to run the car for a couple minutes?

 

as long as you run 91-93 grade gas you should never have to use a fuel cleaner.

 

If needed, I think seafoam is still considered one of the best. You can use it in your top end too.

 

Ya if you use Top Tier premium fuel there is no need for fuel system cleaner but once in a while is good.

But if you do want to try one, Techron and Redline SI-1 are two of the best, and when I use it I usually put it in before a long trip that way it gets used up in one shot.

 

I rarely use one. Maybe one every 10k miles. Only because I somehow get them for free.

I've used Redline in the past,

 

As a precaution, I run Chevron Techron every 10k miles. If the car is going to sit for more than 3 days, Lucas in the tank.

 

never.

 

Never used them and never will.

 

I used Techron and Redline SI-1 and gumout with regene. Good stuff help increased my MPG big time before a long trip. Used it every 5k. before the trip 30mpg with gumout ~33mpg drove from merced to LA

 

dump some techron in ... can't hurt but if ur using top tier gas u shouldnt need it

 

Aren't all fuel system cleaners just slightly more distilled gasoline with an extra helping of detergent?

 

The pour-in kind are. Not very effective.
The only good way to clean a dirty system is open it up replace and sand blast clean.
Ethanol is often what fouls up the system.

 

For years...on all my vehicles I have always run Lube Control LC20 and FP Plus. The LC20 is for the oil and the FP Plus is for the gas. Together, they help burn carbon deposits and lubricate your fuel system. Check out their website here... http://lubecontrol.com/index.php

You can only buy it directly from them. I can't confirm that it actually helps increase your gas mileage, but I like the piece of mind that it is always running through my system helping to lubricate and eliminate water.
