Is HEET better than Seafoam for Water in Fuel? Let's find out!

  • Published on: 17 December 2018
  • Which product works best for removing water contaminated fuel: Seafoam, HEET, or Isopropyl Alcohol? In this video, we test each of these products in water and we also test how they do with preventing and melting ice that's formed in gasoline.

    I think your test of premixing then freezing is bogus as you mixed in somewhere between 40 and 100 times more additive to gas ratio than dumping a full can in a half tank of gas. Another thing to consider is that modern fuel injected auto engines self adjust the mix to compensate for the amount of alcohol in the fuel. Some will run with up to 85% alcohol aka E85 so they will auto richen. I used to work for the state and the guys in the fuel lab told me to add a bottle of Heet to the tank half full when the weather gets cold but above freezing to burn off the water in the tank. I live in a very humid climate and did this regularly and ran my gasoline powered truck 23 years with zero water in fuel problems. I also ran 2 or 3 cans of Berryman fuel injector cleaner a year always on a half tank of gas. Zero injector issues.

    The idea is to add the HEET before your fuel line can freeze, not to thaw a frozen line. 🤷‍♀️

    I used to use iso-heet in my old suburban with a leaky gas tank. Never had a problem with frozen fuel lines but I'm sure it contributed to corroding the tailpipe.

    Another video that fueled some questions … what if you used stable marine stabilizer with other additives like sea foam or heat to see if they run any better

    I had my fuel line on a diesel pickup truck freeze up while driving in Ottawa, Ontario Canada at -25C, and I was luckily already prepared for winter fuel issues, since I already was carrying Methyl Hydrate. 4L jug for about $10-$11.My diesel has an electric lift pump along the frame rail, and a mechanical injector pump at the engine. I got out to listen if my lift pump was working, and no noise coming from it. I grabbed the Methyl Hydrate from inside the truck, and splashed about 1.2 a cup down the fuel fill tube, and the moment it made it to the fuel, I started to hear my lift pump make an ever increasingly progressive noise from quiet to normal audible levels in about 8 seconds from pouring the Methyl Hydrate. You can find it in the paint section where you'd find paint thinner, mineral spirits, etc. There are 2 exciting features about it that fascinates me, it works almost instantly, and its dirt cheap for an amount to last you a year of problem solving.!!

    Isopropyl Heet at likely 99% concentration in the red container (the only 'dry gas' I will use), is far far superior to the methanol in the yellow bottle. A 5 inch column of the 91% isopropyl rubbing alcohol tested would already have close to a half an inch of water to start with, before additional the water added in the test. The heavily corrosive properties of alcohol in fuel is a real problem, especially on aluminum though.Thanks for your thorough, methodical tests. I really enjoyed the vid, you have a lot of patience and mechanical aptitude.

    I replaced a new fuel pump the previous owner had replaced in a dirty Tahoe tank, in the coldest part of winter in my driveway. Phase separation was evident in a clear 2 liter bottle. Water, slushwater/alcohol mix & cloudy fuel clearly in 3 layers. Particulate present too.

    If it's gasoline (petrol) then plain paint thinners work well

    That's probably why the bottom of my boat fuel tank is discolored. Sits all winter and everything separates.

    use methylated spirits , it mixes with water and fuel.

    lol the first one is literally just methanol. Is it fair to assume it has an insane price markup?

    You should see what a Water/Methanol mix burns in a jet engine. Our Alison 501D13 Turbo Props had Water/Meth injection. On a real hot day in an area like Phoenix, Water/Meth injected into a jet engine would increase the SHP (Shaft Horse Power).

    There is a difference between Condensation and Water. Heet removes Condensation. Condensation in a fuel system measures way less than a quarter of a teaspoon.

    Nice! I have been using seafoam for years and always buy non ethanol gas! Another tip is to put a gallon or two into your vehicle first before you fill up your cans at the gas station. This clears the hose and pump of any ethanol fuel!

    No cold pizza and beer in the fridge is an issue!! Great testing, ran into this issue today... not the freeze... but the water..

    Winter form of diesel/petrol required legally in central Europe. I expect it is the same in US.And in winter it is not a question if diesel stops starting, but when. With petrol there is no problem.If you have Praga V3S (still in use), you make a small fire under the engine to heat it a little bit up and put burning newspaper into the air intake when starting. Once it starts, all ice will melt soon.

    IN THE 70'S UP ON THE CANADA BORDER WE USED FPPF IN DIESELS OR POWER SERVICE,AND KEPT TANKS FULL AS POSS.. BUT THE BEST THING WITH THAT WAS THE DEVICE CALLED THERMAL BLENDER,WHICH FED HOT RETURN FUEL OFF THE HEADS BACK INTO THE FUEL FILTER THAT KEPT THE FUEL AT 45 F EVEN AT 35 BELOW ZERO.UPS HAD THESE ON ALL THEIR NORTH REGIONAL DIESEL RIGS.I ALSO HAD A "SOUTHWIND HEATER" THAT WOULD HEAT THE COOLANT WITH A GASOLINE FIRED BOILER,AND 12V. CIRC. PUMP.I COULD TURN MY TRUCK OFF IN SUB ZERO COND.FOR 8HRS, AND TURN ON THAT SW HEATER AND IN A HALF HOUR START LIKE IT WAS SUMMER.

    Thanks pal. As always very informative. Now I have to find something that works. Unfortunately it seems nothing beats a warm garage. I had always used HEET. A full gas tank in freezing temperatures was one of the ways I could be able to park outside and use the vehicle reliably in the very cold temps. HEET seemed to work in those circumstances. What now?

    Hair dryer on fule lines and crab.. to melt it. then isopropyl alcohol for the rest of the winter. My old ATV that sits for months at a time.

    What's the point of any of these if it'll just create a water mixture that the engine can't run off of. Wouldn't this be engine suicide

    1 part water to 16 parts gasoline would amount to a full gallon of water in many fuel tanks! A full gallon? That's huge! A few ounces of water is a more typical amount per vehicle, resulting from condensation in the gas tank, gas station reservoir or automotive fuel line. The tests should be run accordingly.

    Seafoam always worked the best as long as the shop was pushing it for commissioned sales. After that heet was by far the best. Seafoam is basically water anyways.I was a bad salesman. Didn't push product like corporate wanted me to with their special sales commission offers. Honest guys get repeat customers which is better in the long run.

    I was wondering if a 4th bottle was used heat in the red bottle. I wonder how well it would work against the yellow heat bottle? Thank you for your videos, Wyoming.

    WW2 corsairs and I think P-51 mustang's used a mix of coolant injected in gas to escape during a dogfight. Adding coolant in an emergency added 20 hp or maybe just longer range if returning to an aircraft carrier. Pretty good idea... til the coolant runs dry of course. So question is, does adding a small % water increase fuel economy or the good ol throttle response.
