Star Tron Enzyme Fuel Treatment
Gasoline Fuel Stabilizer and Ethanol Fuel Treatment for Vehicles, Boats and Small Engines
Star Tron Enzyme Fuel Treatment Classic Gas Formula is a multifunctional gasoline fuel additive designed to help stabilize fuel, control ethanol-related fuel problems, disperse moisture, and keep fuel-delivery systems clean.
Its enzyme-based formulation is intended for gasoline engines including cars, trucks, boats, motorcycles, powersports equipment, lawn equipment, generators, and other small engines. It is also suitable for gasoline engines using premixed 2-cycle fuel.
Star brite states that Star Tron can stabilize gasoline for up to two years when used as directed, while helping control gum, varnish, carbon deposits, and fuel degradation that can contribute to hard starting and poor engine performance.

- Can be used at every gasoline fill-up
Ethanol Fuel Treatment
Ethanol-blended gasoline can absorb moisture from the surrounding air.
If enough water accumulates, the gasoline and ethanol portion of the fuel can separate into layers, a condition commonly called phase separation.
Star Tron is formulated to help prevent this by dispersing water throughout the fuel as very small droplets that can pass through the engine during normal operation rather than collecting in the bottom of the fuel tank.
This makes Star Tron useful in gasoline equipment that may be exposed to humid conditions or remain unused for long periods.
Fuel Stabilization for Storage
Gasoline can degrade during storage and form gums and other deposits that interfere with:
- Carburetor passages
- Fuel injectors
- Fuel lines
- Fuel-system components
Star brite states that Star Tron can stabilize gasoline for up to two years when used as directed.
This makes it particularly useful for:
- Boats
- Motorcycles
- ATVs
- Lawn mowers
- Generators
- Snowblowers
- Seasonal vehicles
- Lawn and garden equipment
- Equipment placed into winter storage
Star Tron can be used during normal operation as well as before seasonal storage.
Gum, Carbon and Varnish Control
Star Tron is designed to help remove and prevent deposits including:
These deposits can interfere with fuel delivery and combustion, contributing to hard starting, rough operation, reduced throttle response, and fuel-system contamination.
Keeping the fuel system cleaner can help maintain normal engine performance.
Gasoline Engine Applications
The Classic Gas Formula is intended for gasoline-powered equipment including:
- Cars
- Pickup trucks
- Boats
- Outboard and inboard engines
- Motorcycles
- ATVs
- UTVs
- Personal watercraft
- Lawn mowers
- Chainsaws
- String trimmers
- Leaf blowers
- Generators
- Snowblowers
- Other gasoline-powered small engines
It can be used in both 2-cycle and 4-cycle gasoline engines.
2-Cycle and Premix Fuel Compatibility
Star brite identifies the Classic Gas Formula as suitable for engines using premixed gasoline and 2-cycle oil.
Star Tron does not replace 2-cycle oil.
Always maintain the fuel-to-oil ratio required by the engine manufacturer.
Star Tron Treatment Ratio
The PSC-linked Product Data Sheet for Product Group 143 gives the following treatment rates:
| Use |
Treatment Rate |
| Initial Treatment |
1 fl. oz. per 3 gallons |
| Regular Refill |
1 fl. oz. per 6 gallons |
Package coverage at the normal refill rate:
| Package Size |
Treats Up To |
| 8 oz. |
48 gallons |
| 16 oz. |
96 gallons |
| 32 oz. |
192 gallons |
Add Star Tron to the fuel tank just before filling with gasoline.
Star brite states that overdosing this formula is not harmful.
Star Tron Classic Gas vs. Concentrated Formula
Star brite offers several Star Tron formulations with different treatment ratios.
The Classic Gas Formula, Product Group 143, uses a regular treatment rate of 1 oz. per 6 gallons.
The separate Concentrated Gas Formula, Product Group 930, is more concentrated and uses a lower treatment rate.
Always follow the directions printed on the exact Star Tron product being purchased rather than applying the treatment ratio from another Star Tron formula.
Star Tron Gas Formula vs. Diesel Formula
Star brite also sells dedicated Star Tron products for diesel fuel.
This PSC page is associated with the Classic Gas Formula and should primarily be used for gasoline applications.
For diesel engines, use the applicable Star Tron diesel formulation and its corresponding treatment instructions.
Frequently Asked Questions
What is Star Tron Enzyme Fuel Treatment?
Star Tron is a gasoline fuel additive and stabilizer formulated to help control ethanol-related fuel problems, disperse moisture, stabilize stored fuel, and keep the fuel-delivery system cleaner.
Is Star Tron a fuel stabilizer?
Yes. Star brite states that Star Tron Classic Gas Formula can stabilize gasoline for up to two years when used as directed.
Does Star Tron work with ethanol gasoline?
Yes. Ethanol-blended gasoline is one of its primary intended applications.
Does Star Tron prevent phase separation?
Star Tron is formulated to help prevent phase separation by dispersing water throughout the gasoline as very small droplets that can be removed during engine operation.
Does Star Tron remove water from gasoline?
Star Tron does not physically separate water from the tank. It disperses small amounts of moisture into the fuel so the water can pass through the engine during normal operation.
Can Star Tron fix old gasoline?
Star brite states that Star Tron can help rejuvenate old or degraded fuel. Severely contaminated or badly degraded gasoline may still need to be removed rather than treated.
How long does Star Tron stabilize gasoline?
Star brite states that the gasoline formula can stabilize fuel for up to two years when used as directed.
How much Star Tron should I use?
For the Product Group 143 Classic Gas Formula, the PSC-linked PDS specifies 1 oz. per 3 gallons for the initial treatment and 1 oz. per 6 gallons for regular refill treatment.
Can I use too much Star Tron?
Star brite states that overdosing the Classic Gas Formula is not harmful. Using the recommended treatment rate remains the most economical approach.
Should I add Star Tron before or after filling the tank?
Star brite recommends adding Star Tron just before filling the fuel tank.
