I think that you guys are missing the best part of the Seafoam! Bug Fogger, I like to use it in the spring time when the mosquitos are just coming out. Then drive around the block, keeps the bugs away for a while. ; )

 

For 3 tankfulls of fuel---Put a can of seafoam in the tank and drive it, refill tank and add a bottle of Chevron Techron to the tank and drive it, refill tank and lastly add 12oz Marvel Mystery Oil to tank and drive(lubricates fuel pump and injectors). Measure your mileage with each tankful.

Also during this time, use the water cleaning method. Warm the engine, hold revs to about 2000rpm, use a spray bottle and spray the mist into the air intake tube or throttle body. The engine might slow down, just slow your spraying. Do about a pint of water is a good start. Drive it and then repeat with 1/2 can seafoam and then drive it. Put the other 1/2 can seafoam in the oil and drive it. After a tank of fuel, change the oil and replace with your favorite and Bosch filter. I like Mobil 1.

New O2 sensors from RockAuto always helps.

 

Thanks

 

Ok, I was very curious this time and I broke down and gave in to my curiosity.

I read so much about the Sea Foam and steam cleaning the engine that I tried it on my two Cherokees.

Mine, which I just did a full tune up and oil change, I did the steam cleaning with the water in the intake. On my wife's, which I was about to do all that to, I did the Sea Foam first.

On mine, a little steam, but no real black crap on the ground as a show of carbon being cleaned from anywhere. I did it for 20 minutes and nothing.

On hers, I did the Sea Foam in the brake intake (1/3 can), put a third into the crank case through oil fill, and the rest into the gas tank. Then shut it down for a while. During the administration of the fluid while running, nothing. No big plume of smoke, no black crap on the driveway. Then I started it later, and still nothing.

I'm definitely not sold on either of these methods even though there's alot of literature supporting it. Maybe it works, but I didn't see any evidence.

Still haven't driven either of them as I'm doing extensive work to both, but I guess I'll see.

Probably from here on out will go with the BG44K or the B12.

Just thought I'd share my results.

Thanks

 

maybe your engines are really clean internally. I did the seafoam on my 95 and the smoke show lasted well over 15 min of driving and the jeep ran significantly smoother afterwards.

 

Your engines may simply not be very dirty inside. The folks who see the largest difference after cleaning have the most crap caked on. Using a good fuel and keeping things tuned up has a lot to do with that.

 

Yesyesyesyesyesyes this.

 

Well, you're all probably right. Even when I took off both throttle bodies to scrub them, the one was basically clean, and the other had just a tad of residue on it. Even inside the air intake looked pretty clean.

Just wish they were that "RUST" free!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Both throttle bodies? Nvm, forgot that you were workin on two different XJs here

 

44K all the way!!!

Water instead of Seafoam!!

 

Also on that 44k bandwagon.

 

Yep. If you have ever used it, you're a believer. Been using it since the mid 80s with excellent results.

 

Yep, use it once and you won't want to use anything else again

 

Yep. Unfortunately those who have used seafoam support it like those who voted for Obama. Don't know of anything better, and keep touting the attributes of what they believe in.

 

No sea foam here !! Go to dealer get a can of decarb was less than sea foam !
I love the mopar decarb its good stuff .

I bought oil filter adaptor O ring kit and a can of decarb was 12 bucks out the door.
