Petroleum-Based Formula

Sea Foam SF-16 Extreme Marine Motor Treatment isn't necessarily as extreme as advertised but the product is pretty good, especially considering its modest price tag. The product is very popular among professional mechanics as well as the DIY crowd. It works wonders cleaning injectors, carb jets, and passageways.

At the same time, it is no less effective at cleaning and lubricating intake valves, pistons, and cylinders. As far as we can tell, the only disappointing factor here is the bottle. Its shape makes it a little inconvenient to pour the solution down the fuel tank.

Other than that, the product is as good as they come. It will not fail to dissolve and clean fuel residue in different fuel systems (gasoline and diesel engines, carbureted or fuel injected).

The solution is particularly effective at dissolving oil deposits in the crankcase. That being said, it is just as good at cleaning timing chain tensioners, VVT actuators, and quiet noisy lifters.

The petroleum-based formula is especially helpful towards spark plugs. It is able to remove accumulated carbon and prevent the usual late ignition issue.

Bottom line, Sea Foam SF-16 Extreme Marine Motor Treatment will be able to dissolve and clean fuel and oil residues and deposits, stabilize fuel, control moisture, and lubricate upper cylinders. The formula isn't necessarily efficient but about as potent as they come. As far as the price-performance part is concerned, the product is the best fuel injector cleaner in this selection.

Clean It All

Red Line 60103 isn't the cheapest product on the list but its formula is particularly effective and efficient. It will allow you to clean injectors, carburetors, valve, and combustion chamber deposits using a concentrated blend of the most potent high-temperature and low-temperature detergents available on the market today.

The solution will be able to clean just about all forms of fuel injectors, including GDI. It will not fail to improve fuel stability and reduces gum and varnish formation. But the best part is probably that this fuel injector cleaner will be able to reduce your engine's octane reliance by up to two points.

At the same time, the product is especially good at cleaning pollution control valves. The fact that the formula incorporates synthetic upper cylinder lubricants also adds the product bonus points because it improves the engine's overall performance and durability. Other than that, the product works very well with oxygenated fuel and is perfectly safe for continual use.

On the negative side, the solution has a strong chemical smell to it.

All things considered, Red Line 60103 Complete SI-1 will definitely let you pass the smog test. The product will be able to turn the most neglected vehicle into an efficiency machine. It doesn't hurt that the formula is very well-rounded too.

Make Your Engine Great Again

With STP 78577, the biggest selling point is the price and the product's overall price-performance ratio. Considering the price tag and how effective the formula is, 2 x 5.25 fl. oz. bottles for somewhere around 10 bucks is a bargain. As for that effective part, the product will not fail to unclog dirty fuel injectors to restore performance.

It will be able to remove harmful deposits that sooner or later always lead to hard starts, lost acceleration, and rough idling. The solution will help you save on gas in the long run and restore your engine's lost power and acceleration.

Generally speaking, with the concentrated detergents that the formula contains, you shouldn't have any issues dissolving and removing harmful carbon, gum, and varnish deposits on fuel injectors.

The high concentration is also what makes the formula so efficient too. The 5.25-ounce bottle will be enough fuel treatment per 21 gallons of fuel. You won't have to use the solution more often than every 4000 miles, making the product's formula the longest lasting formula on the list.

In our humble opinion, the product's only flaw is that the label on the neck of the bottle is an impractical idea, to say the least.

Apart from that, STP 78577 is an excellent option for people looking to make their engine work as good as new.

What Is a Fuel Injector Cleaner?

A fuel injection system is not necessarily the cornerstone of your average automobile but it is the part that no car can do without. You need to keep it clean. Otherwise, the harmful carbon, gum, and varnish deposits will always lead to hard starts, lost acceleration, and rough idling. The best fuel system cleaners will let you do just that.

Though relatively similar, different cleaners have different formulas and, as you would imagine, these formulas can differ too. The best solutions will be able to clean and lubricate carburetors and injectors, making the fuel burn more thoroughly. The right solution is able to clean the entire fuel injection system, including intake valves and combustion chambers.

Some cleaners can dissolve oil deposits in the crankcase. Certain products will be able to clean timing chain tensioners, VVT actuators, and quiet noisy lifters. Other than that, we would recommend the cleaners that can work with all forms of fuel injectors, including GDI.

Engine cleaners and tire shines do not necessarily work together with fuel injector cleaners, but they will let you improve your car's performance just as much, so consider looking into these products too.
