For consumers · Engine oil
The same MaxDx1 liquid. A dedicated oil-treatment dose.
MaxDx1 is officially supported for engine-oil treatment at every oil change, using one fluid ounce per quart of engine oil.
Why it fits
Fuel treatment and oil treatment use different doses.
The same MaxDx1 liquid is used in engine oil, but the oil-treatment instruction is separate from fuel dosing.
- Use one fluid ounce per quart of engine oil
- Add at every oil change
- Compatible with supported mineral and synthetic motor-oil applications
What MaxDx1 supports
