Best Fuel Stabilizer and Conditioner for fuel-powered engines. PRI stabilizer restores and treats gasoline, diesel fuel, and kerosene.

Difference between gasoline and diesel

Briefly, gasoline is a solvent while diesel is more like oil. Diesel fuel has sufficient lubricity to lubricate the fuel pump and the injectors. Swapping in some gasoline takes away this lubrication, leading to damage. Excessive oil in gasoline gums up components creates blue smoke and messes up spark plugs. Given fuel viscosity is so different, Power Research Inc. devised a fuel conditioner for both categories.

PRI products come in two distinct blends. PRI-G is for Gasoline blends while PRI-D is available for Diesel and Kerosene.

Fuel Stabilizer Magical Ingredients

The best fuel stabilizers protect the fuel system, improve fuel economy, restore engine power, and increase engine durability. Most fuel treatments are sold cheaply with many benefits.

The magical ingredients in most marine fuel stabilizers are hydro-treated paraffinic distillate and solvent naphtha. These two elements prevent ethanol in gas from turning crud a condition that clogs fuel lines.

If you plan on storing a boat, car truck, heavy equipment, lawn mower, or small engine during the winter season, it is highly recommended you use PRI-G or PRI-D FUEL STABILIZERS.

Why the Best Fuel Stabilizer is so important?

Many equipment owners who store their motors for a season forget about leftover fuel. The Ethanol remaining in the gas can turn into a crud mixture, which will get into the fuel system and cause issues.

Stabilizing fuel is an essential procedure that should be done before storing your lawn mower, weed eater, boat, or any motorized equipment. Good fuel Stabilizers do more than stabilize fuel they stop resin buildup, lubricate the engine, remove water, and much more.

High-quality fuel treatment is recommended for treating aged fuels as protection against paraffin buildup and ethanol damage.

As discussed earlier, most fuel stabilizers use a blend of paraffinic distillate and solvent naphtha, which produces a mixture that resists evaporation. PRI fuel treatment also lubricates the fuel system and removes carbon deposits.

5 Best Fuel Stabilizers

STA-BIL 360 Marine Fuel Stabilizer

Sta-Bil 360 Marine stabilizer is a 5-1 formula that cleans the fuel system, maximizes fuel economy, prevents ethanol damage, improves engine power, and removes water from the tank.

Dissimilar to many other alternatives, this one is suited for boat engines and other related water-based engines. Mostly because of a vapor technology that removes water from tanks and helps prevent corrosion damage.

It stabilizes fuel and keeps it fresh when the boat is stored. Sta-Bil usage is recommended at every fill-up, 1 ounce treats up to 5 gallons of fuel.

In general, it is one of the better marine fuel stabilizers you can buy and it is ideal for boats, jet skis, and other water sports engines that are kept in storage during the winter.

PRI Boat Fuel Stabilizer

PRI-G fuel stabilizer can treat as much as 512 gallons of fuel with just 32 ounces of treatment. It is a super concentrated solution appropriate for all gasoline 2 and 4-stroke engines and works well to prevent damaging engine deposits and restore lost performance.

Even though PRI is comparable in price to Sentry an alternative, the impressive treatment of 512 gallons of fuel cannot be matched by any other fuel stabilizer. So in actuality, it calculates to be the cheapest and best fuel stabilizer per gallon of fuel.

PRI-G is one of a few treatments that contain no alcohol. This is important because solutions that contain alcohol tend to dissolve salt a corrosive substance that eventually passes through the fuel system. A common use for alcohol is more power. PRI products are designed for longevity and overall performance.

In a nutshell, PRI-G is the best alcohol-free fuel stabilizer you can buy and calculates out to be the cheaper fuel treatment per gallon.

Star Tron Enzyme Fuel Treatment

Star Tron is a concentrated Enzyme formula that may be used with all gasoline engines for seasonal storage. Star Tron claims its solution will stabilize fuel for up to 2 years and bring the old fuel back to life.

Further benefits of this marine fuel treatment are that it cleans the valves and injectors, increases fuel efficiency, and reduces emissions. It is another popular method of curing and preventing ethanol fuel problems that engines suffer from.

Star Tron Fuel Stabilizer recommends the first dosage is 1 ounce per 8 gallons of fuel. When refilling less treatment is needed, use 1 ounce per 16 gallons of fuel.

Star Tron formula is one of the best ethanol fuel treatments available and between this and the Sta-Bil, there is not much to divide or split them apart.

Sentry New Technology Fuel Treatment

Sentry is not a particularly big brand in the boating industry but they produce reputable fuel treatments for an array of marine equipment. This SD formula treats gasoline engines and will eliminate water and stabilize the fuel.

This product is suitable for all grades of small outboard motors that are 2 or 4-stroke and will increase lubrication and clean the fuel injectors. A 32-ounce bottle will treat up to 80 gallons of fuel perfect for the marine environment.

The Sentury ethanol fuel treatment is an excellent all-rounder, but slightly more expensive when compared to Sta-Bil and Star Tron alternatives.

Briggs & Stratton Fuel Treatment

Briggs and Stratton fuel treatment is often the cheapest product to buy however, it only treats 80 gallons of fuel per 16 ounces. Yet, this is more than adequate for boat owners storing boats with small engines.

This treatment targets ethanol problems head-on with triple anti-oxidant protection and corrosion inhibitors. In terms of stabilizing, it stabilizes fuel for up to 3 years.

This concentrated formula is highly recommended for gasoline engines for engine protection, easier starts, and long-term fuel stabilizing as stated by the manufacturers.
