Fuel efficiency
Helps improve fuel economy when evaluated in the actual operating environment.
For consumers · Road vehicles
Fuel and oil support for everyday vehicles.
For supported gasoline and diesel cars, pickups, and light trucks, MaxDx1 helps support fuel economy, lubricity, cleaner fuel systems, and engine performance.
Why it fits
Designed around real-world driving benefits.
Use MaxDx1 with the fuel grade required by the vehicle manufacturer. Its supported role is fuel enhancement, cleaning, and lubricity—not replacing required premium fuel.
- Supported for gasoline and diesel road vehicles
- Helps restore engine performance and fuel-system cleanliness
- Can also be used in engine oil at the approved oil-treatment dose
What MaxDx1 supports
Performance benefits, stated responsibly.
Results vary by engine, fuel, duty cycle, baseline condition, dose, and test method.
Lubricity
Helps reduce friction and wear across supported fuel and oil applications.
Cleaner operation
Helps keep injectors and fuel systems clean while reducing smoke and deposits.
Engine performance
Helps restore performance affected by friction or deposits.
Practical guidance
Use the correct dose. Measure the real result.
Measure MaxDx1 against the actual fuel or oil volume. Do not estimate from container size when the tank or crankcase is only partly filled.
Initial fuel treatment
Use two fluid ounces per 10 U.S. gallons of gasoline or diesel for the first tank only.
Normal fuel dose
After the first treatment, use one fluid ounce per 10 U.S. gallons at every fill.
Engine-oil treatment
Use one fluid ounce per quart of engine oil at every oil change.
Use only in supported non-aviation applications. Results vary by engine, fuel, condition, duty cycle, dose, and test method.
