I was thinking Seafoam. I have the 7.5L. Let me know. Thanks.

I'm also looking for an additive for the fuel. Seafoam again?

 

Personally I do not believe in oil additives. What are you trying to repair?

 

I just bought the truck, it has about 100k on it and I was buying into the hype that those additives actually help somewhat to burn off the gunk inside.

 

I use seafoam regularly in my fuel. When I bought my 92 F250 earlier this year I did run half can of sea foam through the crank case for a couple of days to help remove and sludge/varnish or what ever. I personally do not add anything to the crankcase on a regular basis. i only did it on this truck because I did not know the condition of the engine. I know people that add seafoam or other additives regularly to the crankase

Seafoam the engine to clean it, then lucas oil stabilizer in the oil. Many claim its snake oil but an old E250 doesnt lie when you go from burning 1qt every week to 1qt a month.

 

Lucas oil stabilizer just bumps up the effective viscosity. You would get the same leak- or burn-reduction results by going up one or two weights. But it does do that part of what it promises.

But at a price. As those Lucas counter-top displays with the gears in them will prove, oil that's been treated with their oil stabilizer goes cling to surfaces in contact with that oil. As the displays also prove, such oil froths and retains those air bubbles in the oil. This aerated oil mixture is then circulated throughout your engine and into your bearings and other critical lubricated parts. The trapped air displaces oil that should be in that space.

Last I looked, air was not a good lubricant for an internal combustion engine.

 

I ran a product called "Restore" through my motor on my second oil change when I got my truck. It smoked like hell for about a week after I put it in, some nice thick black smoke on start up usually, but that would stop quickly. But, it might just be a placebo effect, I think it gave the truck a little more get up and go, and it quit using oil up after that. They have a fuel system cleaner too, but I've never used that specifically.

 

Black smoke would indicate a rich condition or incomplete combustion. Blue smoke would be oil getting by the rings.
Most guys use Seafoam to clean the combustion chamber by adding it to the fuel or into the intake through a vacuum hose. Years ago (the last century) I used a product from GM called top engine cleaner that you would use like Seafoam and it worked to clean up a SBC that had wicked bad valve guides.

Other than Berrymans B12 twice a year and drygas if its going to be below 10 deg, I don't "add" anything to my vehicles. I do use the proper oil and have gone synthetic on everything but the oil in my 300. The 300 has 242k miles and doesn't burn or leak oil so I'm not going to change to synthetic. I do use Motorcraft or Purolater filters on my Fords.
YMMV

I've always put 15w40 in my truck in the summer and 10w40 in the winter.
I'm also aware what the smoke color indicates, but I think it was just burning up whatever crud that got kicked loose. Like I said, it only happened for a short time, then it went away. Hasn't used any noticeable amount of oil since I put that in, probably 2 years ago already.

 

I just used some BG products in my truck and it seems to be running smoother. Look up
BG Quick Clean
BG 109
BG MOA

I used the 109-moa set. You pour in bg 109 into the old oil, run truck for 15 min till it's hot, then run about 10 min. In those 10 min you throttle to 1500 rpm and let off. Do it a few times a minute. Drain oil, then replace filter and fill with new oil of choice. Add BG MOA to the new oil It is an additive that helps clean and enhance oil properties.
Often times additives seem unnoticeable, but this is awesome stuff. It breaks up deposits and is potent! It will stink your garage up when you drain the old stuff. It is a good heavy duty cleaner.
Here is the link, check it out. You can buy the BG-MOA-109 kit together.

marvels mystery oil is what my family has used for years.i am sold its awsome for oil additive.

 

nothing but good reviews on seafoam. have to remember when you put a additive you stand a chance of loosing up stuff and where to that stuff go.

 

I second this I've used BG 44k fuel system cleaner and it does a fine job.

 

ATF and Marvels will work. I would suggest a few oil changes with Rotella. It's high detergent and keeps it clean.

 

Add me to the Marvel Mystery Oil list. I've used it for as long as I can remember about once a year. Never had a problem.

A good long 200 mile drive also helps.

If using a gas additive; in my opinion I would wire brush and re-gap spark plugs after it burns through.
