Antifriction treatment for industrial engines


PROLAB's TMI-369 is the most complete and best performing antifriction treatment for industrial engines on the market. Its advanced formula enhances the quality and performance of mineral and synthetic motor oils.

Characteristics and Benefits

The TMI-369 antifriction treatment for industrial engines is formulated with high quality components. When added to motor oil, it reduces friction, ensures smoother engine running and prevents start-up wear, most notably in cold weather. The TMI-369 clings to surfaces and consequently reduces metal on metal friction.  It contributes to the restoration of the original engine power, the improvement of engine performance as well as fuel economy for both diesel and gasoline.  TMI-369 is a safe product due in part to the fact that it does not contain any chlorine or Teflon: it prevents filter clogging and provides exceptional resistance to contaminants such as water, oil and antifreeze. Thus, TMI-369 maintains oil cleanliness and extends its useful life thereby requiring less frequent oil changes.

Types of Application

Use TMI-369 antifriction treatment in all diesel or gasoline 4-stroke engines, especially in extreme conditions like heavy equipments and large industrial engines.


The TMI-369 antifriction treatment for industrial engines is compatible with all mineral and synthetic oils.

Directions for Use

After the first 5000 km or 80 hours of usage, add TMI-369 to engine oil with each oil change. Add between 7% and 10% of oil pan capacity. For best results, add TMI-369 to new oil and change filter. For engines with between 40 000 km and 80 000 km or with between 750 hours and 1500 hours of usage, PROLAB's DM-30 engine decontaminant should be used beforehand (see DM-30 specification sheet).


The TMI-369 antifriction treatment for industrial engines replaces the following PROLAB products: TMN-33 (new engines), TMU-36 (used engines) and TMD-39 (diesel engines).


TMI-369 is not intended to repair mechanical defects.
