Sea Foam users?

I've had multiple mechanics tell me it's "OK".

They all suggested what is, in their opinion, a better product, Cheveron's Techron concentrate.

My Audi mechanic suggested it exclusively. It worked fine, but probably not any better than getting the car out on the open road and blowing the carbon out of it - which, by the way, he also suggested. ;)
 
I'd be a little concerned about putting a slug of anything into the gas in my high mileage car after reading these posts. OTOH I drive it 30 miles on the freeway twice a day, so maybe it has no carbon scabs!

Ah yes, the "Italian Tuneup"... best results I've seen, tho, is using Gumout WITH REGANE (important) when you're on fumes, then add 5 or 6 gallons, and drive like hell for 20 minutes. Staggering difference.

The consensus is that if you drive more than 20 miles nonstop, carbon doesn't build up due to the engine getting hot enough to burn it off. Read that many times. ??
 
Eh.. it's OK for what it is.. meant to clean up a fuel system over time.. slowly..

I just had to pull the carbs on one of my motorcycles and clean them yesterday.. Yeah, I forgot to close the fuel valve and run the carbs dry before the winter..

I had been trying the seafoam in them and letting it sit, but it didn't make a dent..

Pulled the carbs and tried cleaning with the sea foam.. it was that green gunk that happens from brass parts in the carb.. the seafoam wouldn't touch the stuff... Carb cleaner did a little better, but it took a lot of rubbing and scraping to get them clean..

I still have some I'll pour in as I add more gas, but bang for the buck, I just don't see...
 
Gosh only one mention of Marvel Mystery Oil. Invented in 1923 it is much cheaper then Sea foam and does so much more I have used it for decades. My Father uses it, and it goes back to Crips Trucking that worked in the
Cody, Wyoming area during WW2 they used it. great stuff.

I just found a jug of Marvel at a garage sale and was looking around on it too, but this was a Sea Foam thread so I didn't get into it.
 
I thought it was a mixed drink. Oh-that was a Sea Breeze!

On a semi serious note it as a good product when used according to directions.
 
A Sea Breeze is pretty cool on hot beaches.

ONWARDJAMES mentioned "The Italian Tuneup". I'm not saying it will work all the time, but I've actually once had an amazing result with "Blowing the carbon out".

About 10 or so years ago, I had a classic Audi 100 with a straight 5 cyl. It had well over 200k on it so I was really starting to baby it. It started running a bit rough, and sluggish. I was on I-95 in South Carolina (2 lane Highway each direction in that state as opposed to many states of 3 lane) and was behind a minivan in the passing lane that was shadowing a Truck doing 55 in a 65 mph zone. 5 miles, 10 miles (I flash my lights), 15 miles. The lady just keeps driving 55 in the passing lane shadowing the truck and talking on her cell phone oblivious that she's holding up traffic. Now I'm livid. I'm trying to get to a meeting and I'm going to be late. FINALLY, the truck slows way down so I can get in front of him and pass her on the right - me and about 50 cars behind me. As I pass Miss Ignoramus on her cell phone, I Floor the old Audi for about 1/4 mile. You should have seen the smoke out of the rear! Worst I ever saw come out of a car. And it was the first time that car had been near redline and over 80 mph in a long time.

The rest of the trip, that old 5 cyl ran like a TOP! :)

Marvel Mystery oil was great with dino oil, not much needed with full synths and the newer stuff.

bobistheoilguy.com is a site dedicated to debunking myths and separating fact from fiction.

and billybatts, my buddy bought a 1974 Chevy Caprice from the quintessential old lady who only drove it to church. This was in 1994, I think, and the car only had 53k on it.

We get it out on the road, and it's putting along. I was driving, so I said, "Hey, hold on a sec....got an idea" and I FLOORED IT up to nearly 100. That engine coughed, sputtered, and then pinned us to the seats. That big motor came alive.

It had been so long, the carb flaps were gummed up and wouldn't fully open. We doused it in carb cleaner, and wound it out a few more times.

No more probs!
 
I have been using it for years and it is the real deal! If you put it in with a full tank of gas and your problems still persist you can feel assured that your carb or injectors are clean from gunk. Two different kinds for each application.
 
A friend of mine told me he's using Lucas gas treatment in his small engines. Apparently it keeps the gas good even through the winter, and they seem to run better. Comes in a tall thin bottle.
 
I've used Marvel Mystery Oil on everything from Oiling Air Tools to lubricating mechanical clock gears to Oiling Turntable Motors. It's good stuff. I've never put it in my tank, but when used according to directions, it can't hurt.

I would agree, but I'm fond of additives and going the extra mile.

I will, however, relay something that bobistheoilguy.com once said, and it has stuck with me.

The formula for oil is like baking a cake. You don't make a cake better if it calls for 3 eggs, by adding 12.

Just food for thought.

I think we live in an era with oils of such superior refinement that thermal/wear breakdown of a motor is pretty much a rare event. Much more likely is all the electronics geegaws going south, and pretty much just getting tired of driving said car. My Miata has 180k, my ranger has 137 (but the odometer works when it chooses, so who knows) and my old Honda had 300k when it was rear-ended.
 
When it comes to cars, what duct tape and wd40 won't fix, marvel mystery oil, seafoam, and berryman's b12 will. I've heard horror stories about lucas oil additive (though they say the transmission additives are worthwhile) so I stay away. I felt I've never really needed to add protection beyond what quality oils and lubricants can provide.
 
I tend to agree with you guys, in most cases if it ain't broke there's no need to fix it. Certain things, like preventing fuel degradation in storage, call for preventative additives. When something actually needs fixing, it's good to know about these products, and the Italian Carbon Blowout option.
 
Back in the day my old '71 Chevy developed noisy lifters. I was working at a gas station back when full service was still available and we had a mechanic on duty. Bill, the mechanic, told me to dump in a quart of AT fluid about 500 miles before my next oil change was due. I did as he suggested and by golly my noisy lifters went away when it came time to change my oil. I'm guessing whatever detergent/cleaning properties of the AT fluid must have cleaned up my lifters or something like that.
 
I just got home from a neighboring town about 30 mi away. A few days ago I purchased a bottle of the Seafoam like was pictured in loopstick's post. I probably had about 1/8 tank of gas before starting home so I pulled over and poured half the bottle in my gas tank and then popped the hood and poured the other half in the crank case then hammered down towards home.
My ol' '99 "Cry-seller" ran pretty damn good on the way home, tank just about empty when I pulled into my garage of course.
Doing an oil change tomorrow.....
 
I used to add Techron it works really good and is aproved by BMW. Now I just use Chevron gas which has Techron in it.
