has any one tried one of those pour in tank fuel treatments. what kind and how were your results.
 
SeaFoam. I have only found it a select Napa stores, but it is sold elsewhere.
You have to use is a couple of time before you will notice anything, but I noticed a smoother idle. It can also be used in the oil and from what Ive heard you can pour it into your TB to clean the carbon out. I have yet to try the last two. Hope this helps!
 
Lucas is what I use for mine. STP and the others seem to do nothing. Lucas has worked for mine. Give it a shot. There is also Marvins Mystery Oil that can be used to clean the injectors and tanks and also goes in the oil to clean that as well. Juice
 
I heard a mechanic on the radio years ago tell the caller to use Chevron Techron to clean their injectors. He had a national show and was based out of Flordia.

Over the years I have used it with excelent results. I now see the big box parts stores like Advance Auto Parts and Autozone both sell it.

Chevron packages their fuel cleaner in 12, 16 and 20 oz bottles. They also have different strengths for lack of a better phrase.

For you XJ you want the 20 oz bottle, they package it one ounce of cleaner per gallon of gas. Since you have a 20 gallon tank you need the 20 oz bottle. Two 12 oz will do in a pinch.

You should expect to pay $6 for the 12 oz bottle and $10 for the 20 oz bottle.

They also offer weaker solution for less money but try to get the bottle with TECHRON in 1/4" letters.

I used it in my one car when I was moving to alabama. With in 30 miles I could tell the engine responded better.

I am sold on Techron and now that I live in an area with Chevron stations I guy their gasoline since they put in a maintenance dose of techron in every gallon.
 
I've heard Click and Clack of Cartalk say additives wont do anything to improve your vehicle, but I've personally never tried any of them.
 
Jeepster or anyone, I was just in a Carquest asking for that BWG44 or whatever it's called, they didn't have it, & one of the desk clerks volunteered that she has used Lucas UCL/Injector Cleaner for years & swears by it. So I bought a 5.25 oz.bottle for $3-something, got it home & can see no instructions for use except that it will treat up to 25 gallons. I'm sure the gallon size has more complete info than this tiny bottle.

I know some of the fuel additives say to put in an almost-empty tank & then fill. I just filled my car. Should I wait til before another fillup & add it the, or can I just dump it in now?

Then what? How often should it be added & in what amt.? I am one of those light-footed drivers who should probably worry about carbon buildup.
 
No, you can add it, the reason for pouring it in on an empty tank is so that the incoming fuel will mix it a bit better, putting it in and driving around will do the same thing. Personally I use the Techron or Valvoline in the gold bottle, both are in the $7 price range, the .99 cents stuff I only use for maintenance between full treatments.
It also helps to clean the throttle body with a spray cleaner if you don't want to pull the throttle body and clean it on the work bench. I just picked up a spray can of gumout that is supposed to be plastic coated safe and used it last week. Got all the carbon off the inside of the throttle body but I still kept it away from the airflow sensor [I'm not that trusting of a label by any means].
Valvoline also makes a gold spray can with a shoot down spray tip which is one handy configuration, I'm just really suprised that the other companies don't have the same down shooting nozzle as the valvoline one.
Seafoam also works well for cleaning the intake and valves, it's a 'pour in and soak' kind that you pour directly into the throttle body till it stalls and then let sit. Warning, it's one smokey startup afterwards though so warn your neighbors :D
It also won't hurt it to take it out on the hiway and do some wide open throttle runs either, that also gets rid of carbon.
