Don't Do It

Would Not Recommend

Tried this in my crankcase oil of my 04 Dodge Diesel. 190K miles and never had a leak. Drove it for 200 miles then went to change oil and noticed rear main seal now leaking. Coincidence not sure but I have seen similar reports of this. I would not recommend this in your crankcase at this time.

Awesome stuff

Would Recommend

I use it in everything. If something isn't running right fuel wise I dump some of this in and let it run for 5 minutes it's usually clears up the fuel issue.

Works! Ford 3 liter duatec taurus

Recently had a tune up. Had a miss on two plugs before the change.plugs were carbon coated bad that came out.i refilled 18 gallon tank two times with a can of regular seafoam. Saw a difference on the first can. Used a can on a half a tank the next. On my third tank I changed to 93 octane premium with a half can. Wow! Immediate difference. Could just be me but the higher octane helped the process.thumbs up.anyone else have this effect? No stumble .fuel mileage through the roof.

My 2007 ATV would hardly run iat all, Even with using a fuel treatment during the winter and last season I ran it a lot, I drained the gas put one can of seafoam and one quart of gas and ran it for half an hour problem solved like new.

30 years and still going strong with Sea Foam.

Would Recommend

In 1994 we bought our 1st snowmobile, added 3 more to the family. That was 30 years ago! Plus we have 3 ATV type vehicles and 2 boats. We have religiously used Sea Foam in our gasoline engines for 30 years. If you care about clean fuel systems, we at Smith Farms believe Sea Foam has the best products and look forward to another 30 years of performance. Top notch products for everyday use, it sells itself.

Running smooth.

I was running a little rough after 13 years on my F-150. Got new plugs. No change. Dumped in a can of Seafoam in a quarter tank and filled up. Drove around normal errands and it got smoother. Drove to Florida 1,200 miles no problems. Got 113k on the ‘09 4.6 V8!

Works Well

Would Recommend

I got a riding mower from my MIL that never started right after sitting for 2 years. I added a tank of fuel with the SeaFoam and used the mower. The next time I got it out, I didn't need the starting fluid to get it running. It saved me from having to get a new carburetor for the mower.
