I thought about putting some through my 73 engine since it has never been apart. Online reviews seem very good. Anything to lose? Other than the cost of a can or two
I have used it for years. I always use it when I get another old car and can usually tell a difference in the smoothness and idle of the engine after running a tankfull through. I have a can if it in the Reatta I just picked up that has been sitting for years.
I use it every year when I put the car away for the winter. I also use it on the mower, and snowblower. You can find it every now and again at Advance auto buy one get one free. When I bought my Buick last year it had been sitting. It was running a tad bit rough. I added some seafoam to the tank and that did the trick.
I use it in everything! Cars, lawn mowers, chainsaws and generators. I have a 55 gallon drum of fuel on hand for the generators. I replace it every 2 years. The fuel runs great in everything. I used to run Stabil in everything but it never worked well.
There was a non-professional test of Seafoam done on a lawnmower engine and Ford 4 cylinder truck engine on Youtube. The guy used a borescope camera before and after, and you could DEFINITELY see the difference on the carboned up lawnmower piston! I've only used it once, but the engine was very clean inside these valve cover when I took it off to replace the leaker. So it may have been a VERY well cared for car by its previous owners.
It's does what it says. I have never used in the oil, though, just the fuel system - on old carb'd vehihcles as well as modern fuel injected.
I worked from 1969-1972 at Supertest Petroleum in London, ON (remember Miss Supertest racing boats). We sold a product called "Combustion Cleaner". This was before seafoam. With the engine at 2000 rpm, u pored this product down the carburetor and u watched black smoke pour out of the dual exhausts. The product was burning off the built-up carbon in the cylinders. I used it & it worked. U could feel it in the engine response.
the "Tune Up in a Can" used it since it was introduced to me in 1983 for all the reasons noted above.
I have used it in every engine I've owned for the past 5 years, this includes outboards, lawnmowers, and engines of all sizes. I love that stuff! I normally throw a can in the gas before filling up and then run some through the vacuum line from the brake booster. Also if it's a car I just got I will normally throw a can in the oil and drive for about 100 miles before I change the oil. It's good stuff, it's petroleum based and just has a good amount of PEA (detergent) in it.
I used Seafoam in the fuel when I first bought my car in 2010. I can't say if it helped or not but it didn't hurt. I can say that "Engine Restore" works well. In 2011 I tuned up my Wildcat and did a hot compression test and found the worst cylinder was #2 at 135 psi and the best was 165 psi on #5. The average was 148 psi. The car had 100K miles at the time. Last year (after running " Engine Restore" every year since 2011 and now at 107K miles) I did a follow up hot compression test and found that the low cylinder was #6 at 145 psi (unchanged from 2011) and the high was #5 at 165 psi (also unchanged). However, #2 is now 150 psi and the average is 154 psi. 6 of 8 cylinders had higher compression (as much as 15 psi increase). When I inherited my late grandfather's stock 1929 Model A in 2015, I found 2 cylinders were about 20 psi lower than the other 2 cylinders (65 psi vs 45 psi). After the first year of running Engine Restore the two lower cylinders are 55 and 52 psi in only a few hundred miles. I could feel the difference in power. I've never been one to use additives but a few I have found to work. Another is Marvel Mystery Oil which works well to unstick valves and lifters.
Was in AutoZone yesterday and they had seafoam for half price. So bought some for my friends Mustang that I was getting a battery for so it would start when they get back from Florida. Did seem to run a little better, so should go back and get some for mine!
IMHO, Seafoam is snake oil. This stuff is much like the old Gumout that cleans the gum and mucous from INSIDE the carb, especially from old/varnished gas (as in 2 stroke motors) and is just about 1/2 the price of the others. Do a little reading here... ws https://www.berrymanproducts.com/pr...-carburetor-fuel-system-and-injector-cleaner/
Yes berryman chemtool is good stuff and works well, however they are not he same product. Chemtool uses very aggressive chemicals that while work well, you should not leave them in your tank and lines for long, where as the seafoam and similar gumout products use petroleum base and a high a mount of PEA which is a much safer detergent to use widely and to leave in the car as well as it also performs some stability to the fuel.
Picked up and maintaining about 1 mpg across a fleet of E-450/V10 shuttle buses. Now, 1 mpg doesn't sound like much but we do about 1.5 million miles per year with 18 vehicles. Every 7k miles they get SeaFoam in the tank. I can see a difference in the plugs at tune-up time too.
