For as long as there has been gasoline, there has been a need for fuel stabilizers. During the refinement process, they’re used to preserve gasoline from degrading.
Only three to six months is the shelf life of gasoline purchased at the gas station. If you’re storing a lawnmower or boat engine for an extended period of time or a classic car for a lengthy period of time, you’ll need gasoline stabilizer.
This is when Sta bil and Seafoam come into play. Fuel stabilizers are the primary function of both chemicals, although they also serve as engine cleansers. The second feature restores the engine’s power, which is sometimes mistaken for an increase in output.
Seafoam and Stabil Storage and Stabil 360 Protection will be evaluated side by side to discover which one comes out on top in this evaluation.
Sta-bil vs Seafoam – Complete Comparison
If you want the most accurate comparison possible, I’m going to include more than just what’s written on the packaging.
It is also crucial to consider the application, duration, effectiveness cost of use as well as any extra features that may or may not help engine efficiency and cleanliness when comparing Sta bil vs. seafoam.
When comparing products, the first thing to look at is how long they can keep the fuel from going bad. When it comes to real-world settings, the stabilization of station fuel only lasts about three to six months.
Boat and lawnmower owners have had to deal with leaking carburetors and rust after leaving the fuel in the tank all winter.
- The Sta-bil Storage fuel stabilizer provides up to 24 months of protection, depending on the concentration.
- The Seafoam fuel stabilizer provides up to 24 months of protection, depending on the concentration.
- The Sta-bil 360 Protection fuel stabilizer provides up to 12 months of protection.
When keeping fuel for more than a year, you have two options: the Sta bil 360 Protection or the Seafoam Sta bil Storage.
The quantity and cost of the stabilizer will be directly affected by the amount of stabilizer utilized.
Using a 12-month storage duration, the following ratios can be calculated:
Here, the difference is plain to see. Seafoam’s effectiveness has been reduced by five times, while Sta bil 360 Protection is twice as effective. Even Seafoam suggests doubling Sta bil Storage’s or Seafoam’s recommended amount for a 24-month storage term, which is double the recommended amount.
Price Per Gallon of Fuel
We need to consider more than just the base price when estimating the true cost of utilizing any of the three fuel stabilizers. For comparison’s sake, we’ll use the 32-ounce containers of Sta bil Protection instead of the 2 x 16-ounce cans of Seafoam.
As of the date/time specified, prices and availability are subject to change. A customer who purchases this item will be subject to the price and availability information that is displayed at the time of purchase on [the relevant Amazon site(s), as applicable].
Even before we get to the price per gallon of fuel, it’s evident that Seafoam’s future is bleak. Sea Foam is currently more expensive than Sta bil 360 Protection by a few dollars, while Sta bil storage costs twice as much.
In terms of cost and cost per gallon, Sta bil is the better fuel stabilizer. My original plan was to utilize the price per gallon of fuel, but after doing the math, I found that utilizing Sta bil would be so cheap that I increased the capacity by ten times.
No matter how long you need to store your belongings, you can choose between Sta Bil 360 Protection and Sta Bil Storage. Sta bil 360 Protection is a newer product, thus I’m leaning toward it over Sta bil Storage because of the price difference.
Added Fuel Additive Benefits
Seafoam has become more than simply a gasoline stabilizer, but what about Sta bil?
The fuel system, fuel injectors, cylinder walls, piston heads, and valve heads are all officially cleaned by both brands.
You can verify this for yourself with a boroscope, which is readily available on the internet. Pull out a spark plug and put in the camera after adding either stabilizer to a full tank of gas and ensuring that the mixture is rich.
If you want to check how clean the engine gets before and after using gasoline stabilizers, use the boroscope to inspect the engine.
The information in the table comes from Seafoam and Sta bil’s official websites, and it focuses more on the company’s marketing strategy than its actual performance. Don’t get me wrong, all three products live up to their claims, but in actual use, the differences in effectiveness and specific components are negligible…
What is the shelf life of fuel?
In a closed container like a fuel tank or jerry can, fuel does not remain indefinitely; gasoline has a shelf life of three to six months whereas diesel has one year. A few of months is all it takes for the organic ethanol to become useless due to oxidation and evaporation.
How to identify bad fuel?
Discoloration and a darker brown color are caused by changes in the chemical characteristics of gasoline over time. It’s a sign of rust in the fuel tank or container if the color of the fuel turns red.
Most of the time, a visual inspection is sufficient to determine if the fuel has gone bad. Another way to tell if the gas you’re using is fresh or stale is by smelling it, as fresh gas has a strong odor, whereas stale gas smells like nothing at all.
Fuel-related problems in modern automobiles are also indicated by a warning light. When the fuel in an older car lacks the volatility needed to produce intense combustions, you’ll notice a significant loss of power, a hard start, and stalling.
Is Sea Foam better than Stabil?
Fuel can be preserved for up to 24 months using Sea Foam or Stabil Storage. Stabil Storage, on the other hand, is 2.5 times more potent and costs half as much as Seafoam. Take a look at how much it costs to run Sta bil and Seafoam by reading this review!
Can I use Sea Foam and Stabil together?
The two products are sometimes mixed together, but I’m not sure what the results would be if you did so. There is no harm in running them at the same time and switching between them, but I’m not entirely sure.
Is Sea Foam considered a fuel stabilizer?
Fuel stabilizer Seafoam is first and foremost, but it also helps to clean and maintain the engine. Seafoam can keep fuel fresh for up to two years in a petrol tank or a container.
Which fuel stabilizer is the best?
Sta bil 360 Protection is the finest fuel stabilizer on the market right now, according to the comparison’s factors.
Can you put too much Sta-bil in your gas tank?
Sta bil should not be used excessively, but it can be increased by up to three times the typical amount without harming the engine or the fuel itself.
Will Sea Foam harm your engine?
Our article on the truth about seafoam goes into great detail, but to summarize, this gasoline stabilizer and additive has no negative effects on the engine and can even improve it by removing residue buildup.
This comparison of Sta bil 360 Protection and Seafoam fuel stabilizers shows that Sta bil 360 Protection comes out on top.
For the best value, it provides up to a year of protection, as well as the benefits of keeping your car clean and running smoothly. Sta bil Storage offers similar benefits to the 360 Protection at a considerably more economical price than Seafoam if you need to keep the fuel stored for longer.
