How to use — 3 easy steps

1
Measure

1 oz per quart of motor oil. Severe duty or large crankcases (10+ qt): up to 1.5 oz per quart.

2
Pour

Add to warm oil at an oil change or between changes. Don't over-treat.

3
Drive

Protection starts at the very next startup. Also works at 1 oz/qt in hydraulic oil, power steering fluid, gear oil & limited-slip differentials.

The details

Description

Molecure Friction Modifier Engine Lubricant — 16 oz

Molecure Friction Modifier Engine Lubricant is an advanced oil additive engineered to reduce friction, heat, and wear where protection matters most—at startup and under heavy load. Using boundary-lubrication technology with anti-wear and anti-corrosion agents, it forms a protective film on metal surfaces to help quiet engine noise, smooth acceleration, and support better fuel economy. Compatible with all gasoline and diesel engines and safe with conventional or synthetic oils, Molecure also helps keep engines cleaner by reducing sludge and varnish formation, supporting longer oil life and extended drain intervals. In diesel applications, it assists with stiction reduction in HEUI injectors and enhances startup lubrication for more consistent performance in tough conditions.

Frequently asked questions

Can I use it in a diesel engine?
Yes — it's formulated for both gasoline and diesel engines. In diesels it also helps reduce stiction in HEUI injectors and improves startup lubrication.
Is it compatible with synthetic oil?
Yes — it works with conventional, synthetic, and blended motor oils.
How much do I add?
1 oz per quart of motor oil. For severe duty or large crankcases of about 10+ quarts, up to 1.5 oz per quart. One 16 oz bottle treats a typical 5-quart engine three times.
Can I use it in anything besides engine oil?
Yes — use 1 oz per quart in hydraulic oil, power steering fluid, gear oil, and limited-slip differentials.
When should I add it?
At every oil change for continuous protection, added to warm oil. Follow your vehicle and oil manufacturer's service intervals.
